45 °Viewfinder Unit II for Nauticam by INON

Olympus mirrorless cameras have a well-deserved reputation for their extensive customization options, outstanding image quality, first-class image stabilization and impressive autofocus. The OM-D E-M1X is no exception, as it is the brand's first professional-level mirrorless Micro Four Thirds camera. For underwater photographers, the E-M1X with its fast continuous shooting, high battery capacity, 4K HDMI 4:2:2 video output and impressive autofocus fulfills almost every requirement they have for a professional camera, with the added benefits of the MFT open-source platform and the convenience of an electronic viewfinder.

With the Canon EOS R, underwater photographers not only get a full-frame mirrorless camera with Canon's Dual Pixel autofocus and the ability to use the EF-S range with an adapter, but also the new RF mount, which enables new lenses with groundbreaking features. The EOS R features a 30.3 MP full-frame CMOS sensor with the new RF lens mount and a 3.7-million-dot electronic viewfinder. The Canon EOS R Camera The Canon EOS R is remarkable not only because it is Canon's first full-frame mirrorless camera, but also because of the many additional features available with the introduction of the RF lens mount. The RF lens mount has the same large diameter of 54mm, but the ability to use larger rear lens elements that are closer to the sensor increases the sharpness in the corners and at the outer edge. The lenses can also be more compact than lenses with the same coverage area in the EF mount. The addition of 4 more lens communication pins to a total of 12 pins expands the functionality of the lenses. RF lenses feature a customizable control ring that will also be available on one of the two EF mount lens adapters and can be assigned to control various exposure settings. On the RF lenses, manual focus is now controlled electronically, which allows the direction of rotation of the lens' manual focus ring to be changed. The EOS R is also able to use the wide range of EF-mount lenses üvia three optional adapters: a simple EF-to-R adapter, an adapter that supports the customizable control ring, and another that offers a drop-in filter port. The features that have made Canon DSLR and Cinema cameras favorites of underwater photographers are also present in the EOS-R, including powerful and precise Dual Pixel autofocus and 4K Canon Log video recording üvia the large 30.2MP CMOS full-frame sensor. Important Camera Specifications 30.3MP CMOS full-frame sensor 8fps continuous shooting 4K UHD recording at up to 30 frames per second All-I ISO 100-40,000   The NA-R underwater gear from Nauticam. The NA-R underwater gear embodies Nauticam's drive for innovation. Both the Canon EOS R and Nikon Z-7/6 cameras offer photographers the ability to use available äolder lenses üvia an adapter in addition to the original optics.  For many, the EOS R is a transition from a Canon full-frame DSLR. To support both conventional and original lenses, Nauticam has integrated the NA-R into the N120 port system.. Use lenses with RF or EF mounts - with the same port system. Canon's EF-to-RF adapters can be attached to the camera before insertion into the housing.  When using the EOS R inside the housing with the adapter and a supported EF lens, the port and port extension are identical to the same arrangement on a Nauticam Canon N120 DSLR. As the range of RF lenses evolves, dedicated port and port extension combinations will be listed in the port overview.   Two lens release buttons, one for RF lenses and one for EF lenses used with the optional Canon adapter, are located on the front of the housing to facilitate lens removal through the portöopening.   Controls. Nauticam engineers are obsessed with giving the photographer unobstructed access to all necessary controls underwater, with as many as possible within easy reach of the ergonomically rubberized grips.  This mission control philosophy extends to the NA-R, which features a dual thumb lever and dual sub-lever on the right grip.   The thumb lever activates the "AF-On" buttons and the lower one activates the "Info" buttons, while the lower lever corresponds to the "M-Fn" and "Record" buttons.  Next to the left grip is a thumb lever for "Playback" as well as a dedicated switch for switching from LCD to EVF.   Large, knurled and rubberized knobs access the camera's "main"and "sub"command controls.  The two-stage off"ser enables smooth focus and off"activation. Additional buttons for "Menü", "focus point selection" and others are also "easily accessible via the handles.. An additional control wheel is located on the left side of the housing and connects to the control ring on the supported EF to EOS R mount adapter with control ring üvia the optional gear (NA19561). Flash triggering Flash output is via one of two optional flash outputs, a manual LED output (NA26301) or a TTL flash output (NA26321), which use the built-in fiber optic ports with optional fiber optic cables to output supported flash units. For control of flashes that do not support fiber-optic flash output, a variety of older flash sockets are available. Video üvia HDMI  The EOS R is capable of outputting a 10-bit 4K UHD (3840 x 2160) 30p video signal üvia HDMI.  When combined with the optional standard M16 HDMI jack (NA25033) and HDMI (D-C) 190mm cable (NA25036), the NA-R can be used in conjunction with an external monitor or recorder such as the SmallHD 502B or Ninja Inferno in their respective Nauticam housings. Vacuum test and leak detection system  The NA-R is supplied with the electronics as well as the M16 II vacuum valve for vacuum testing and the leak detection system. This simple system makes it possible to check the waterproof integrity of the housing before the dive and to monitor it continuously throughout the dive. The Nauticam system is temperature compensated, eliminating false alarms caused by a  change in external temperature or by heating a camera during an action-packed dive.

FUJIFILM X-T3 The Fujifilm X-T3 features an APS-C CMOS 4 X-Trans 26.1MP Sensor. The X-T3 is powered by an upgraded X Processor 4 that is 3x faster and allows for 1.5x faster sensor readout than the X-T3. The base ISO has been lowered from 200 to 160. Oversampled DCI or UHD 4K (using full sensor width) is possible at 30p whereas 60p can be recorded with a minor 1.18x crop. The 60p footage can be captured as 10 bit 4:2:0 H.265 at 200 Mbps and recorded internally. This increases to 4:2:2 when output over HDMI. The X-T3 also features F-Log capture to maximize dynamic range, protecting highlights and shadows for editing. The X-T3 features a Natural Liveview mode when recording F-log that more closely resembles a standard monitoring LUT. Zebra warnings and focus peaking overlays as well as magnification during shooting are all improvements that video shooters will appreciate. Three custom white balance slots are available in addition to the 7 presets. The electronic viewfinder of the X-T3 is vastly improved with 3.69M dots as compared to the 2.36M dots of the X-T2. Battery life has also been improved. The X-T3 can achieve 20fps continuous shooting with Autofocus and this increases to 30fps when shooting from a 1.25x crop area. A Sport Finder mode will show this cropped area inside the EVF. Phase-detection autofocus has been increased to 98% of the sensor area. The X-T3 also features a fast 1/250 X-sync speed. Key Camera Specifications 26MP BSI 'X-Trans CMOS 4' sensor 425-point hybrid AF system 20 fps shooting with AF (11 fps with mechanical shutter) 3.69M-dot electronic viewfinder 10 bit 4:2:0 H.265 internal video capture (4:2:2 over HDMI) UHD/DCI 4K/60p from 1.18x crop region UHD/DCI 4K/30p using full width of sensor Internal F-Log capture Dual UHS-II SD card slots USB C-type connector can be used for charging battery THE NAUTICAM NA-XT3 UNDERWATER HOUSING Nauticam has supported X-T1 and X-T2 cameras and continues to create innovative and ultra-functional housings for this line with the NA-XT3. More than just an updated badge, the NA-XT3 is a complete redesign of the series. With a form factor more closely resembling the NA-A9 for Sony's A9 mirrorless camera, the NA-XT3 features DSLR-style housing and port lock mechanisms as well as integrated ergonomic handles. An optional hand strap (NA28130) can be added to the handles. The housing is designed with our Mission Control concept of placing the most important camera controls as close to the handles as possible to facilitate effortless and quick camera operation to ensure you don't miss the shot. The NA-XT3 features thumb levers near both handles, with the left thumb lever actuating the playback function and the right thumb lever the AF-L control. The housing includes two M14 and one M24 bulkhead openings and an M5 threaded hole on top (underneath the cold shoe) for an additional ball mount. The NA-XT3 uses the N100 Port System shared with the Fujifilm XH1 system. A selection of port options are available for a variety of lenses. VIDEO RECORDING FEATURES The impressive video specs of the X-T3 prompted the addition of some video-centric features to the NA-XT3. The base of the housing can accept Nauticam's Mounting Ball Set for Tripod (PN 25218), the same part as for the NA-A9. As the X-T3 can output DCI/UHD 4K at 60p with 4:2:2 quality over HDMI, a new M24 bulkhead has been incorporated into the housing to support an HDMI 2.0 connection to the Nauticam Atomos Ninja V housing (HDMI 2.0) for Atomos Ninja V 5” 4Kp60 4:4:2 10-bit Recorder/Monitor/Player (17922). Video shooting can decrease battery life so the NA-XT3 is compatible with an optional 2500 mAh USB-C Battery Pack (NA36335) that sits below the camera tray inside the housing. FLASH TRIGGERING Reliable automatic flash exposure is available with the NA-XT3 and a variety of optically fired flashes, precisely reproducing the camera’s included EF-X8 flash at a proportionally greater intensity. This system yields accurate automatic TTL flash performance – even in manual exposure mode – with no electrical sync cables to flood! The NA-XT3 is also compatible with the Nauticam Mini Flash Trigger for Panasonic/Fujifilm (PN 26305). The Flash Trigger allows for rapid fire manual flash firing via fiber optic, with no camera battery drain. The NA-XT3 comes fiber optic ready and accepts standard Sea & Sea style bushing connections. Nauticam Universal fiber optic cable system (NA26216) for Inon, Sea&Sea strobes, provide exceptional light transmission for accurate TTL performance. INTEGRATED VACUUM CHECK AND LEAK DETECTION SYSTEM The Nauticam vacuum check and leak detection system is pre-installed in the NA-XT3 as standard equipment. Combined with an optional M14 Vacuum Valve II (NA25624), this monitoring system provides constant updates throughout the dive as to watertight integrity of the housing via a multi-color LED on the rear of the housing.Lorem Ipsum is simply dummy text of the printing and typesetting industry.

Das neue Gehäuse für die A7 hält, was die A7 verspricht: Vollformatkamera - kleines Gehäuse. Ein neues Port-System wurde für diese Kamera entwickelt.... die für Spiegelreflexkameras verwendete Portöffnung war zu groß, was bedeutet, dass das Gehäuse zu groß geworden wäre. Und die vorhandene Portöffnung für Mirrorless-Kameras ist zu klein für einige der Objektive, die in der neuen Sony FE Objektivreihe erwartet werden. Daher wird eine neue Reihe von Ports mittlerer Größe benötigt und mit diesem Gehäuse geliefert. Das Gehäuse und die neue Portlinie wären nicht komplett mit dem patentierten Nauticam Port-Verriegelungssystem, das, wie bei anderen Nauticam-Gehäusen, ein einzigartiges internes Bajonettsystem verwendet, das den Port sicher und ohne Verdrehen oder Fehlausrichtung verriegelt. Der berühmte rote Hebel ist einfach zu bedienen und lässt den Fotografen sofort erkennen, dass der Port sicher verriegelt ist. Auch die benutzerfreundlichen Gehäuseverriegelungen sind hier zu finden, was den Zusammenbau dieses Gehäuses besonders einfach macht. Der EVF/LCD-Schalter ermöglicht einen schnellen Wechsel zwischen der Verwendung des großen, hellen LCD-Displays und des hochauflösenden elektronischen Suchers (EVF). Das Gehäuse wird mit einem Standard .66x Sucher für den EVF geliefert, der leicht gegen einen der beiden erweiterten Sucher der Nauticam ausgetauscht werden kann. Trotz der geringen Größe ist dies ein sehr einfach zu bedienendes Gehäuse, auch mit Handschuhen. Jede Steuerung ist dort platziert, wo ein Unterwasserfotograf sie haben möchte - schließlich sind die Designer selbst Unterwasserfotografen und bemüht, jedes Nauticam-Gehäuse so ergonomisch wie möglich zu gestalten. Jede Steuerung, ob es nun darum geht, Blende oder Verschlusszeit zu ändern, auf die Autofokussperre zuzugreifen, ISO zu ändern oder die Bildwiedergabe anzusteuern, wird so gestaltet, dass Bewegungen minimiert und die Aufnahme erleichtert wird.  Integriertes elektronisches Vakuumprüf- und Leckerkennungssystem Das Nauticam Vakuumprüf- und Leckerkennungssystem ist serienmäßig mit NA-A7 erhältlich. In Kombination mit einem optionalen Vakuumventil liefert dieses Überwachungssystem ständige Updates zum wasserdichten und tauchsicheren Zustand des Gehäuses. Der Bediener kann auf einen Blick den wasserdichten und tauchsicheren Zustand des Gehäuses erkennen. Ein einfaches, codiertes LED-Beleuchtungssystem zeigt dem Benutzer an, ob das Vakuum stabil ist oder ob das Gehäuse Vakuum verliert. Die Leckageerkennung ist im gleichen Stromkreis integriert, so dass bei Wassereintritt eine akustische und optische Anzeige erfolgt.  Gummierter Zoom-/Fokusknopf: Der neue Zoom-/Fokusknopf ist jetzt gummiert, um das Greifen einfacher und komfortabler zu machen. Nauticam ist der einzige Gehäusehersteller, der umspritzte, gummierte Teile anbietet. Wie bei den vorherigen Nauticam-Griffen erhalten die eingebauten NA-A7-Griffe die Gummierung, die so viele Fotografen zu schätzen gelernt haben. Nikonos Objektivstütze: Alt trifft neu, denn die Nikonos-Objektive werden endlich mit einer Digitalkamera kombiniert, die diesen legendären Wasserkontakt-Objektiven würdig ist. Natürlich ist auch bei diesem Gehäuse die Art von Qualität und Robustheit vorhanden, die zum Synonym für den Namen Nauticam geworden ist. Das Gehäuse ist aus massivem Aluminium gefräst, hat eine Nenntiefe von 100 m und ist langlebig gebaut. Außergewöhnliche Sorgfalt wird verwendet, um jegliche Möglichkeit einer galvanischen Korrosion zu reduzieren, und das Gehäuse ist hart anodisiert, um auch nach Jahren noch gut auszusehen.

Nauticam is pleased to announce the NA-A7II, the newest entry in its mid-range series of fine underwater camera housings. The NA-A7II is an incremental improvement over the outstanding NA-A7 housing, and is the ultimate underwater machine for full frame mirrorless image making. The Sony A7 II Camera The new Sony A7II (officially called Sony Alpha 7 II) follows hot on the heals of the amazing A7, adding some significant improvments, including a 5-axis sensor-shift image stabilization. The A7II, with its 24MP full-frame CMOS sensor, is the ultimate all-around full frame mirrorless camera to date. Focus is improved with a Hybrid AF system utilizing on-sensor phase-detect points. From a design perspective, other improvements in this model include more rugged build quality, a beefier grip, more and better laid out custom buttons, and a more ergonomically placed shutter release button. Other features include a 3-inch tilting LCD, XGA OLED electronic viewfinder, Multi-interface (hot) shoe, Wi-Fi with NFC, and 1080/60p video recording - now with XAVC S and a flat 'S-Log2' picture profile. The A7II features the same highly regarded full-frame 24MP CMOS sensor that was found on the original A7 and it continues to impress. The A7II uses a hybrid autofocus system, which has 25 contrast detect and 117 phase detect points spread across its sensor. Sony engineers claim that autofocus performance has improved by 30% and tracking by 50% compared to the A7. Autofocus and now auto exposure can be used while tracking a moving subject during burst shooting (at 5 fps). Ergonomically, the A7II is improved over the A7, and the difference is obvious when picking up the camera. It feels more substantial in the hand, and the shutter button in particular is more comfortable. The grip is larger and significantly more substantial which keeps the hand in a more relaxed position when gripping the camera. The A7II uses more magnesium alloy and less plastic than the A7; allowing the overall build quality to seem more solid with only a minor increase in weight Like previous models, the A7II supports WiFi, NFC, and a number of apps making sharing very easy, while opening up the camera's capabilities. Underwater Tribe | NA-A7II from Nauticam on Vimeo. The NA-A7II Underwater Housing by Nauticma The NA-A7II looks quite similar to the NA-A7, and the housings are approximately the same dimensions. As those photographers who have experienced the NA-A7 housing have discovered, that housing is a stunning blend of aesthetics, ergonomics and functionality and the A7II housing only reinforces this mission. The NA-A7II ships with built-in, yet adjustable handles, featuring Nauticams famous contoured rubberized grip. The AF/MF/AEL button is given special treatment on the right side of the housing with a direct access lever immediately reachable by the right thumb. This allows the button to be programmed for AF-ON meaning thumb focus fans can easily have perfect functionality. The shutter release can be accessed at the same time, offering extremely quick focus-to-shoot finger action. Like many Nauticam housings, the play button is brought up to the left thumb, and the three command dials (think shutter speed, aperture and exposure compensation) can be adjusted quickly with minimal reach. The ISO button is within short reach of the right thumb, important for video shooters. Speaking of video, the record button is on the top right, thus eliminating camera shake during video start/stop. The Function Menu button opens up common camera settings to a quick menu, and this button is a short reach with the right thumb. The programmable C3 button is a very easy reach and can be programmed for any of several functions. The housing features a switch to change between the EVF and the LCD providing rapid and secure transition between viewing modes, and supports Nauticam's well renowned viewfinders. Installing a lens with a gear attached is made easy by the new pull-out zoom/focus dial. A Nauticam Mini Flash Trigger made specifically for Sony is an available option, allowing the camera to shoot rapid fire with flood free optical cables. The housing includes an M16 bulkhead port for optional HDMI out, Nikonos style sync cable or other external accessory. The NA-A7II accommodates for the larger than expected grip of the camera. Rather than compromise on image quality, the Nauticam designers chose to create ports than take into account this difference, hence a separate entry in the port chart for this housing. Lens Matters The original A7 and A7R cameras from Sony sparked a huge interest in going full frame for mirrorless. For the underwater photographer, this enthusiasm was quickly diminished by the fairly limited lens selection. Underwater image makers rely on very wide angle lenses and macro lenses, and they were nowhere to be found. However, the recently released 16-35mm is a game changer. This is a lens from the Sony Zeiss partnership, quaintly dubbed the Sony Vario-Tessar T* FE 16-35mm F4 ZA OSS. It's a terrific rectilinear wide angle zoom that focuses close and demonstrates very good sharpness all around with medium to large sized dome ports. The Nauticam 180mm dome is an ideal choice for this lens. For macro lovers, Sony two days ago announced a 90mm macro beauty (Sony FE 90mm f/2.8 Macro G OSS), and this lens will be supported as soon as possible after it is shipped (slated for July). Also just announced is a new 28mm f/2 lens with a fisheye adapter, similar to what Sony did with the fisheye and wide angle adapter on the 16mm lens for the NEX series. This is an appealing way to get fisheye, as it allows multiple configurations with a single lens. Look for more info about Nauticam support for this lens when it ships (slated for May). Owners of Canon full frame lenses like the EF 8-15mm f/4L Fisheye USM, EF 100mm f/2.8L Macro IS USM, or the EF 16-35mm f/2.8L II USM lenses will apreciate the ability to use these fine optics with the A7 series. This is made possible with a Metabones adapter (Canon EF Lens to Sony NEX Smart Adapter (Mark III or Mark IV)). These lenses work well on the A7 series, providing both aperture and autofocus control from the camera. Speaking of Lenses Nikonos "water contact" lenses are the stuff of legend, but too many of them are sitting in a box in a closet. Time to dust them off! The full frame A7II is a great way to bring those lenses back to action. With the full frame sensor, this Sea&Sea 12mm or the famous Nikonos 15mm behave like they were intended to. Viewfinder Options The NA-A7II ships with a standard 0.66x viewfinder. This standard optical glass viewfinder is travel friendly and suitable for image makers that care to use the LCD for most framing. Many photographers prefer the ease of a magnified viewfinder with adjustable diopter to take advantage of the excellent EVF in this camera. Nauticam produces a straight 180_ enlarging viewfinder and a 45_ angled enlarging viewfinder to enhance the ease of close quarters work often associated with macro shooting. Both viewfinders have high quality optics, and allow bright viewing of the entire image. A patented external dioptric adjustment allows personal adjustment to a sharp-as-a-tack standard underwater and viewfinder changes can be executed in less than 30 seconds without using tools. Exceptional composition and focus accuracy have never been more accessible. NA-A7II Feature Checklist Unsurpassed build quality, designed by an award winning engineering team, and produced utilizing the most modern manufacturing technology available Ergonomically placed controls with size, shape, and color differentiation Access to all key camera controls All controls clearly labeled Patented two stage shutter release system, allowing precise feel over half press and full press Patented Port Locking System Patent pending Multi Controller pad Lens release button Easy to operate locking housing latches Rubberized ergonomic grips on adjustable handles Laser-cut steel handle brackets Quick release camera mounting plate Optical strobe connectors for fiber optic flash triggering Mini Flash Trigger M16 accessory hole for electrical bulkhead, HDMI or hydrophone installation M14 accessory hole for vacuum valve installation Integrated vacuum monitoring and leak detection circuit (valve optional) Dual 1" (25mm) strobe mounting balls included as standard equipment 1/4-20 tripod mounting holes Dual M5/M10 threaded accessory mounting points 100m Depth Rating Integrated Vacuum Check and Leak Detection System The Nauticam vacuum check and leak detection system is available with NA-A7II as standard equipment. Combined with an optional vacuum valve, this monitoring system provides constant updates on the water tight and safe to dive status of the housing. A simple coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The housing ships with a rear bulkhead port specifically for installing optional vacuum valves, leaving the other bulkhead port available for HDMI, sync cables and other accessories.

The evolution of the mirrorless interchangeable-lens camera has been happening at a fever pitch over the last few years with Panasonic leading the field of introducing more video-driven improvements.  With the LUMIX DC-S1H, Panasonic is taking its full-frame mirrorless S1 platform and giving it supercharged cinema-video specs.  The S1H is the first full-frame mirrorless camera to offer 6K (3:2) 24p internal recording with 14+ stops of dynamic range.  The Nauticam NA-S1H, with its M28 bulkhead supporting HDMI 2.0 output, can be combined with the Atomos Ninja V and Shogun Inferno external monitors/recorders to offer even more recording and monitoring Options. THE PANASONIC LUMIX DC-S1H CAMERA The Panasonic S1 brought many of the features that made the GH series of micro-four-thirds cameras popular with underwater image-makers to a full-frame sensor.  With the S1H, Panasonic has taken some of it's VariCam cinema-tech and added it to already strong video capabilities of the S1 platform.  The most notable is the ability to record 6K in a 3:2 aspect ratio at 24p (or 5.9K, 30p at 16:9) at a reported 14+ stops of dynamic range.  If 60p is important, the S1H will also capture C4K/UHD4K at 60p in 4:2:2 10-bit internally.   THE NAUTICAM NA-S1H UNDERWATER HOUSING As the S1H is an evolution of the mirrorless camera, the NA-S1H is the progression of Nauticam's innovative approach to housing design and construction.  As the capabilities of the cameras housed within increases, so must the housing itself.  The NA-S1H is a perfect compliment to the S1H camera and is designed to take full advantage of the S1H's advanced video capabilities.   EF AND L LENS SUPPORT Sigma's MC-21 EF to L adapter allows for the use of Sigma EF-mount lenses to be used with the S1H camera. The NA-S1H Housing is designed to not only accommodate the adapter but to allow for the use of the existing focus and zoom gears for Canon EF-mount Sigma lenses for the N120 Canon System along with the existing Canon N120 extension ring and port combinations for those lenses.  As native L-mount lenses become available, those best suited to underwater use will be added to the system. MISSION CONTROL The NA-S1H follows Nauticam's Mission Control design philosophy that emphasizes placing the control where it is needed most, regardless of where it may be on the camera itself.  This has led to housings where the majority of essential controls can be easily reached from the ergonomic handles.  The use of thumb-levers allows for the manipulation of many controls without having to remove your hand from the handle which leads to more time spent focusing on the shot and less time looking for a control. The NA-S1H features dual thumb levers on both the right and left rear of the housing.  The left side activates Playback and DISP buttons while the right controls AF-ON and REC.  An inner lever on each side adds additional functionality with ISO for the front right and LVF on the left rear.  A multi-position switch on the rear of the housing accesses C/M/AF and is located next to the multi-directional pad. HDMI 2.0 The NA-S1H features the large-bore M28 bulkhead that supports HDMI 2.0 video output connections to external recorders/monitors such as the Atomos Ninja V and Shogun Inferno with the optional Nauticam HDMI 2.0 cables and monitor housings.  An HDMI 1.4 option is also available for those monitor housings that do not feature the M28 bulkhead.

The NA-A7II looks very similar to the NA-A7 and the housings have about the same dimensions. Nevertheless, this is an underwater housing specially tuned for the Sony alpha 7 Mark II. The NA-A7II comes with integrated adjustable grips that feature Nauticam's famous rubberized grip. The AF/MF/AEL button has been specially equipped on the right side of the grip with a direct access lever that can be reached instantly with the right thumb. This allows the button to be programmed for AF-ON, which means that "thumb focus" fans have perfect functionality. The output can be operated at the same time, allowing simultaneous focusing and shooting. As with many Nauticam housings, the playback button is placed on the left thumb, and the three adjustment ratios (shutter speed, aperture, and exposure compensation) can be set quickly and with minimal reach. The ISO button is located immediately near the right thumb, important for videographers. The record button is located in the upper right, preventing shake when starting/stopping video. Underwater Tribe | NA-A7II from Nauticam on Vimeo. The function menu button öopens the general camera settings for a quick menu, and this button is not far away with the right thumb. The programmable C3 button is very accessible and can be programmed for one of several functions. The housing features a switch to toggle between the electronic viewfinder and LCD, allowing quick and safe switching between viewing modes, and supports Nauticam's familiar magnifying viewfinders. A Nauticam mini flash output designed specifically for Sony is an available option that enables the camera to shoot quickly with flood-proof optical cables. The housing includes an M16 connector for an optional HDMI output, Nikonos sync cable, or other external accessory. The NA-A7II accommodates the camera's unexpectedly large grip. Rather than compromise on image quality, Nauticam designers chose to create ports to account for this difference, hence a separate entry in the port table for this housing. High-quality professional look Sony's original A7 and A7R cameras sparked a lot of interest in using full-frame for mirrorless cameras. For the underwater photographer, this enthusiasm quickly waned due to the relatively limited lens selection. Underwater photographers rely on very wide angle lenses and macro lenses, and these were nowhere to be found. This changed spätestens with the release of a 16-35mm wide-angle zoom. This is a lens from the Sony Zeiss partnership, designated the Sony Vario-Tessar T* FE 16-35mm F4 ZA OSS. It's a terrific straight wide-angle zoom that focuses close and offers very good all-around sharpness with medium to large dome ports. Nauticam's 180mm dome is the ideal choice for this lens. For macro lovers, Sony has launched a 90mm macro lens (Sony FE 90mm f/2.8 Macro G OSS). Also available now is a 28mm f/2 lens with fisheye adapter, äsimilar to what Sony did with the fisheye and wide-angle adapter on the 16mm lens for the NEX series. This is an attractive option for fisheye lenses, as it allows for multiple configurations with a single lens. Owners of Canon full-frame lenses such as the EF 8-15mm f/4L Fisheye USM, EF 100mm f/2.8L Macro IS USM or EF 16-35mm f/2.8L II USM will appreciate the versatility of their lenses with the A7 series. This is made possible by a Metabones adapter (Canon EF Lens to Sony NEX Smart Adapter (Mark III or Mark IV)). These lenses are well suited for the A7 series and allow both aperture and autofocus control via the camera. Finder options Precision requires foresight: a camera like the Sony A7 II / A7RII requires perfect focus for optimal results. Fortunately, Nauticam has developed the most user-friendly interchangeable viewfinders on the market. The standard optical glass viewfinder is very good and travel friendly, but many photographers prefer the convenience of a magnified viewfinder with adjustable diopters. Nauticam produces a "straight" 180º magnifying viewfinder and a 45º angled magnifying viewfinder to facilitate the tight-space work often associated with macro shooting. Both viewfinders feature high-quality optics and allow bright viewing of the entire image. A patented external diopter adjustment allows for personalized, pin-sharp adjustment underwater. Viewfinder changes can be performed in less than 30 seconds without tools. Exceptional composition and focus accuracy have never been so accessible.  Vacuum inspection and leak detection system The Nauticam vacuum prüf and leak detection system is available as standard with NA-A7II. Combined with an optional vacuum valve, this monitoring system provides constant updates on the watertight and submersible condition of the housing. The operator can see at a glance the watertight and submersible condition of the walker. A simple coded LED lighting system indicates to the user if the vacuum is stable or if the walker is losing vacuum. Leak detection is integrated into the same circuit so that an audible and visual indication is given when water enters.

Als professionelles Gehäuse, das zu einer Vorzeigekamera passt, bietet das NA-A9 Unterwassergehäuse Zugang zu allen wichtigen Kamerasteuerungen in einem robusten und zuverlässigen Aluminium-Unterwassergehäuse.  Entscheidende Änderungen der Kameraparameter werden von den Griffen aus vorgenommen, ohne umständliche Reichweiten. Basierend auf unseren erfolgreichen NA-A7- und NA-A7RII-Gehäusen ist dieses neueste Gehäuse für Sonys Alpha-Flaggschiffkamera sicherlich ein unverzichtbares und zuverlässiges Werkzeug für den professionellen und ambitionierten Unterwasserfotografen, um die Vorteile des Funktionsumfangs der A9 voll auszuschöpfen. UNTERSTÜTZUNG EINER BREITEN PALETTE VON OPTIKEN  Mit dem gleichen Objektivanschlusszubehör wie das Nauticam NA-A7II-Gehäuse wird derzeit eine Liste von dreizehn Sony FE-Objektiven unterstützt. Ein Adapter ermöglicht die Verwendung der gesamten N120 DSLR-Objektivreihe und unterstützt die beliebten Canon EF-Objektive, die an der A9 mit einem EF auf Sony E-Mount Objektivadapter befestigt sind. Ebenfalls erhältlich ist ein Adapter zur Befestigung der Objektive der UW-Nikkor-Serie, die ursprünglich für die Nikonos Unterwasser-Entfernungsmesser-Systeme verwendet wurden. Von ultrabreiten Fisheyeobjektiven bis hin zu langen Makro-Objektiven - das Nauticam A9-System deckt alle Brennweiten ab. MODERNE WASSERKONTAKTOPTIK Inspiriert von den Wasser-Kontaktoptiken-Designs der letzten Jahrzehnte entwickelt Nauticam ständig neue optische Zubehörteile, die die Messlatte dessen höher legen, was in der Unterwasser-Fotografie möglich ist.  Entwickelt mit moderner Objektivdesign-Software und vollständig optimiert für den Einsatz im Wasser, bieten diese Objektive eine deutlich bessere Leistung als ein In-Air-Objektiv hinter einem Dome- oder Flat-Port allein. SUCHER Der standardmäßige optische Glassucher ist sehr gut und reisefreundlich, aber viele Fotografen bevorzugen die Erleichterungen eines vergrößerten Suchers mit einstellbaren Dioptrien. Nauticam produziert einen "geraden" 180º vergrößernden Sucher und einen um 45º abgewinkelten vergrößernden Sucher, um die Arbeit auf engstem Raum zu erleichtern, die häufig mit Makroaufnahmen verbunden ist. Beide Sucher verfügen über eine hochwertige Optik und ermöglichen eine helle Betrachtung des gesamten Bildes. Eine patentierte externe Dioptrienverstellung ermöglicht eine persönliche, gestochen scharfe Anpassung unter Wasser. Sucherwechsel können in weniger als 30 Sekunden ohne Werkzeug durchgeführt werden. Außergewöhnliche Zusammensetzung und Fokusgenauigkeit waren noch nie so zugänglich.  BLITZAUSLÖSUNG Ein optionaler LED-Blitzauslöser (NA26302) ermöglicht die schnelle Blitzauslösung mit optischen Nebenblitzen über Glasfaserkabel. Das NA-A9-Gehäuse verfügt über zwei eingebaute optische M10-Buchsen, die mit dem optionalen LED-Blitzauslöser kompatibel sind.  Blitzsysteme, die elektrische Synchronkabel verwenden, werden an ein Nikonos Anschluss und Blitzschuh (NA25056) angeschlossen.  INTEGRIERTES VAKUUMPRÜF- UND LECKERKENNUNGSSYSTEM Das Nauticam Vakuumprüf- und Leckerkennungssystem ist serienmäßig mit NA-A9 erhältlich. In Kombination mit einem optionalen Vakuumventil liefert dieses Überwachungssystem ständige Updates zum wasserdichten und tauchsicheren Zustand des Gehäuses. Der Bediener kann auf einen Blick den wasserdichten und tauchsicheren Zustand des Gehäuses erkennen. Ein einfaches, codiertes LED-Beleuchtungssystem zeigt dem Benutzer an, ob das Vakuum stabil ist oder ob das Gehäuse Vakuum verliert. Die Leckageerkennung ist im gleichen Stromkreis integriert, so dass bei Wassereintritt eine akustische und optische Anzeige erfolgt.  Das Nauticam-System ist temperaturkompensiert und eliminiert Fehlalarme, die durch eine Änderung der Außentemperatur oder durch die Erwärmung einer Kamera bei einem actionreichen Tauchgang verursacht werden.  

Nauticam hat Gehäuse für eine Vielzahl von Mittelformat- und Mirrorless-Gehäusen hergestellt.  Die NA-GFX50S nimmt all diese Erfahrungen auf und ist das erste Gehäuse für eine digitale Mirrorless-Mittelformatkamera. Nauticam bietet weiterhin ungehinderten Zugang zu den wichtigsten Funktionen, die Unterwasserfotografen benötigen.   Die GFX50S verfügt über 10 anpassbare Tasten.  Das "Q"-Menü der Kamera kann auch an die am häufigsten verwendeten Menüpunkte angepasst werden.  Das Menü "Q" ist leicht zugänglich über den Doppel-Daumenhebel auf der rechten Seite, der auch auf die zuweisbare Taste "Fn 4" zugreift.  Mit dem linken dualen Daumenhebel werden die Funktionen "PLAY" und "DELETE" aufgerufen.   Die FOCUS-Pianotaste auf der rechten Seite aktiviert den Joystick, um den Fokuspunkt zu ändern.  Die GFX50S verfügt über insgesamt 117 Kontrastfokuspunkte, die weiter unterteilt werden können in 425 einzeln wählbare Punkte.  Die benachbarte Piano-Taste aktiviert die Taste "Fn 5" der Kamera. Blitzauslösung Die Blitzauslösung erfolgt über eingebaute Glasfaserbuchsen mit dem Fujifilm EF-X20 TTL-Blitz, der bei Montage am Blitzschuh in das Gehäuse passt. Flash EV kann über einen Drehregler auf dem Gehäuse gesteuert werden und der Status kann über spezielle Ansichtsfenster angezeigt werden.  Der Blitz kann über einen Hebel auf der linken Seite des Gehäuses ein- und ausgeschaltet werden.

Die Leckageerkennung ist im gleichen Stromkreis integriert, so dass bei Wassereintritt eine akustische und optische Anzeige erfolgt. Das Nauticam-System ist temperaturkompensiert und eliminiert Fehlalarme, die durch eine Änderung der Außentemperatur oder durch die Erwärmung einer Kamera bei einem actionreichen Tauchgang verursacht werden.

Die NA-XT2 übernimmt das Beste aus den bisherigen Spiegereflex- und Mirrorless High-End-Nauticam-Gehäusen und übernimmt gleichzeitig die manuelle Blendensteuerung, die für diese spezielle Kamera erforderlich ist. Das Gehäuse ist klein, jedoch nicht auf Kosten der Funktionalität oder Ergonomie. Integrierte Griffe bieten eine stabile und komfortable Basis für die Bedienung des Systems. Ein ergonomischer Auslösehebel und gut platzierte Drehregler sorgen für ein hervorragendes Tastgefühl. Wichtige Drucktasten befinden sich in Reichweite der Griffe. Die Kamerasteuerungen haben genügend Abstand, um eine einfache Bedienung, auch mit Handschuhen, zu ermöglichen. Zusammen mit dem NA-XT2 wurde ein neues Zubehör-Akkupack auf den Markt gebracht!  Diese Batterie mit größerer Kapazität verlängert die Zeit zwischen den Batteriewechseln erheblich und ermöglicht es, dass das Gehäuse zwischen den Tauchgängen geschlossen bleibt. Der Akkupack schiebt sich bequem in das Unterwassergehäuse unterhalb der Kameramontageplatte. Das Fujinon XF10-24mm F4 R OIS Weitwinkel-Zoomobjektiv und das Zeiss Touit 2.8/50M Makroobjektiv werden unterstützt. Mit Fujis High-End-Objektiven (genannt "XF"-Linie) und dem Zeiss 50mm-Makro wird die Blende nicht elektronisch durch die Kamera, sondern über einen Objektivring gesteuert. Dieser Old-School-Ansatz wird bei jedem ankommen, der zum Beispiel mit älteren Nikon Spiegelreflexkameras vor den Tagen der elektronischen Blende gearbeitet hat. Verwenden Sie den Nauticam-Blendenring (NA36422) für das Zeiss 50mm Makro und (NA36421) die Blende, (NA36441) die Zoomräder für die 10-24mm. Die sichere, einzeln drehbare Gehäuseverriegelung öffnet den Gehäuseboden. Die Kamera lässt sich leicht einführen. Der O-Ring des rückwärtig montierten Gehäuses erleichtert die Wartung. Zwei faseroptische Synchronisationsanschlüsse sind Standard und nutzen die Vorteile des mit der Kamera gelieferten EF-X8-Blitz für die Blitzauslösung. Um das Beste aus dem exzellenten elektronischen Sucher X-T2 (EVF) herauszuholen, ermöglicht Nauticam die Installation der beliebten 45º- und 180º-Vergrößerungssucher, die eine optimale klare Komposition und Fokussierbarkeit bieten. Blitzstecker für Glasfaserkabel TTL Mit dem NA-XT2 und einer Vielzahl von optisch ausgelösten Blitzen ist eine zuverlässige automatische Blitzbelichtung möglich.

Sony, pioneers of the full-frame mirrorless camera with their A7 line have brought us their latest iteration and it is awesome. Taking cues from the just-released A9 the A7RIII adds better autofocus, faster continuous shooting, and the still-awesome 5-axis stabilization rated at an amazing 5.5 stops. 4K is recorded from downsampled 5K using the full sensor width or the Super 35 crop mode is also available for a little in-camera zoom. THE SONY ALPHA A7R III The Sony a7R III is the company's latest high-resolution full frame mirrorless camera. Much like Nikon's recent D850, it's one that combines resolution with high speed and fast autofocus capabilities to a degree we've not previously seen. The Sony a7R III achieved an overall DxOMark sensor score of 100 points, the same as the Nikon D850. This makes it the highest-scoring mirrorless system camera to date, beating the A7R II by two points. The a7R III is built around it's 42MP BSI CMOS sensor and can shoot up to ten frames per second. 4K footage can be captured either from the full width of the sensor or from a Super 35 size crop. The camera can also shoot 1080p video at up to 120p and has a function to conform this footage back down to 24 or 30p, if you want out-of-camera slow-mo. These functions are also available from both the full width of the sensor or from the cropped region. 5-axis image stabilization ('Steadyshot') is available in all modes. The a7R III inherits many of the lessons learned from the company's pro-sports model, the a9. This means faster processing, improved autofocus, improved handling and ergonomics, as well as the adoption of a much larger battery! Sony Alpha a7RIII Key Camera Specifications 42MP BSI CMOS sensor Faster, lower-noise image processing 10 fps shooting with full AF, 8 fps with 'live' updates between shots 3.69M dot (1280 x 960 pixel) OLED viewfinder Improved autofocus, including more tenacious Eye AF mode 5-axis image stabilization, rated at 5.5 stops (CIPA) with 50mm lens 4K footage from 'Super 35' crop region oversampled from 5K capture Video AF less inclined to refocus to background 'Picture Profile' video gamma/gamut modes including S-Log2 and 3 Twin SD Card slots (one UHS-I and one UHS-II compatible) Bayer-cancelling multi-shot mode for improved resolution True 14 bit uncompressed Raw, even in continuous drive mode Use of phase detection (including Eye AF) at 3 fps with adapted lenses THE SONY ALPHA A7 III CAMERA A full frame mirrorless 24.2 MP sensor that offers 14 bit RAW imaging at 10 fps. The sensor itself is 5-axis stabilized and features 693 phase-detection AF points covering 93% of the image area in addition to 425 contrast-detection points.

Ergonomic camera control access is one of the defining strengths of a Nauticam housing, and the NA-7RIII continues this tradition. Essential camera parameter changes are made from the handles, without awkward reaches. The NA-A7RIII housing inherits the core design elements from the Nauticam pro DSLR range, and bundles them in a more compact package. A patented port locking lever allows lens changes to be made in seconds. Opening the housing for quick battery and media changes is fast and easy with the locking housing latches. All aspects of the system are a seamless extension of the camera. The NA-A7RIII is equipped with two M16 and one M14 bulkhead. This allows for the addition of a variety of bulkhead accessories such as a Vacuum Valve, electronic flash triggering bulkhead, and even HDMI Bulkheads for video. With "clean" 4K 4:2:2 HDMI output, pairing the NA-A7RIII with an external recorder from Atomos will enhance the incredible video capabilities of this camera even more. 4K is created from oversampled 5K when recording in-camera to UHS-II cards giving extremely high quality internal recording as well. Vacuum Check and Leak Detection System The Nauticam vacuum check and leak detection system is shipped with NA-A7RIII as standard equipment. With the addition of the optional M14 Vacuum Valve (NA25624) this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple color coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The Nauticam system is temperature compensated, eliminating false alarms caused by a change in outside temperature, or from a camera heating up on an action packed dive.

The GFX, Fujifilm’s mirrorless digital camera system, has achieved the highest level of image quality in the world of professional photography. The GFX100 uses a 55mm diagonal length large format CMOS sensor with over 100 million pixels which makes this the highest class resolution mirrorless digital camera ever produced. The Nauticam NA-GFX100 and the N120 Port System supports the dedicated lineup of GF lenses. THE FUJIFILM GFX 100 CAMERA The Fujifilm GFX 100 is equipped with a 102MP sensor which is 1.7 times larger than that of a 35mm full-frame sensor. It offers fast and reliable autofocus, in-body image stabilization, and 4K video capability. Built for extreme environments, the GFX 100 is weather resistant and freeze proof to -10ºC. Key Camera Specifications 102MP medium format CMOS sensor (43.8 × 32.9mm) with Bayer array On-sensor Phase Detection 5-axis image stabilization Continuous shooting up to 5fps Weather-sealing 4K video with 4:2:2 10-bit HDMI output 5.76M-dot removable OLED viewfinder 16-bit RAW Capture Dual SD card slots (UHS-II) THE NA-GFX100 NAUTICAM UNDERWATER HOUSING Nauticam has produced housings for a variety of both medium format and mirrorless housings. The NA-GFX100 takes all that experience and produces the most ergonomic housing available for a mirrorless digital medium format camera. Nauticam has continued to offer unencumbered access to the essential controls that underwater photographers need. The GFX 100 has 15 customizable buttons. The camera's "Q" menu can also be customized to accommodate most-used menu items. The "Q" menu is easily accessed by the double thumb-lever on the right hand side which also accesses the "AF-ON" button critical for back button focus. The left hand double thumb lever accesses the "PLAY" and "DISP/BACK" functions. The directional keys on the right hand side engage the joystick to easily change the focus points. The GFX 100 has a total of 3.76 million phase detection auto focus points. Above the directional keys is a rotating lever which allows you to quickly change the focus mode. FLASH TRIGGERING Flash triggering is performed via built-in fiber optic bulkheads using the Fujifilm EF-X20 TTL flash which fits into the housing when mounted on the hot-shoe. Flash EV can be controlled via a dial atop the housing and status can be seen through dedicated viewports. The flash can be turned on and off via a lever on the left side of the housing. PREMIUM PROFESSIONAL OPTICS The GFX 100 uses a new lineup of dedicated lenses with the moniker GF. The Nauticam N120 Port Systems supports many of those currently available including ultra-wide primes, zooms, and macro lenses. VIEWFINDERS The standard optical glass viewfinder is very good and travel friendly, but many photographers prefer the ease of a magnified viewfinder with adjustable diopter. Nauticam produces a ?straight? 180º enlarging viewfinder and a 45º angled enlarging viewfinder to enhance the ease of close quarters work often associated with macro shooting. Both viewfinders have high quality optics, and allow bright viewing of the entire image. A patented external dioptric adjustment allows personal adjustment to a sharp-as-a-tack standard underwater and viewfinder changes can be executed in less than 30 seconds without using tools. Exceptional composition and focus accuracy have never been more accessible. INTEGRATED VACUUM CHECK AND LEAK DETECTION SYSTEM The Nauticam vacuum check and leak detection system is shipped with NA-GFX50S as standard equipment. Combined with an accessory vacuum valve this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple color coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The Nauticam system is temperature compensated, eliminating false alarms caused by a change in outside temperature, or from a camera heating up on an action packed dive.

Underwater photographers rely on the diversity of the environment to push their art to its limits, and not just underwater. With the introduction of the Nikon Z7 and Z6, the full-frame mirrorless camera market has important new competitors to push the segment even further. Nikon's first full-frame mirrorless cameras, the Z7 and Z6 offer underwater photographers the same legendary Nikon sensors with the versatility of an electronic viewfinder and the more compact form factor of a mirrorless system. The NA-Z7V supports both the Z6 and Z7 models and features the larger M28 bulkhead that supports HDMI 2.0 connections required for the Atomos Ninja V recorder/monitor. The Nikon Z6 and Z7 cameras For many full-frame Nikon photographers, the appeal of a mirrorless camera was tempered by the thought of having to invest in and master a new system by switching to another ecosystem like Sony. For those who were waiting for a mirrorless system that utilises Nikon's image processing technology and ergonomics, the wait is over. The Z6 and Z7 cameras have an identical body, differing only in features - an ideal feature when it comes to housing the camera for underwater use. Both camera bodies are built around the new Z-mount. With an incredibly large mount diameter of 55 mm (17% larger than F-mount) and a very short flange distance, the Z-mount offers a maximum aperture of F0.95. While the current selection of Z-mount lenses is limited, almost the entire range of F-mount lenses can be used with the optional FTZ adapter. When using the adapter, lenses without VR also benefit from the in-camera stabilisation. VR and Z-mount lenses get 5-axis stabilisation, while non-VR F-mount lenses have 3-axis stabilisation. There is also a special e-VR (electronic VR) that combines optical and electronic stabilisation for video recording. Both the Z6 and Z7 can internally record UHD 4K at 30 frames per second or 1080 HD at up to 120 frames per second at 144 Mbps. Recording utilises the full width of the sensor and both cameras are capable of outputting UHD 4K in 10-bit N-log via HDMI, supporting start/stop control. The electronic OLED viewfinder (EVF) of the Z6 and Z7 offers 100% image coverage at Quad VGA resolution (3.69 million dots). When triggering external flashes, both cameras have a 1/200 X-Sync shutter speed. Nikon Z7 Camera The Z7 has a high-resolution 45.7MP FX-format sensor that allows shooting at up to 9 FPS. The Z7 offers a wide ISO range of 64-25,600 and autofocus is achieved with 493 on-sensor AF points covering 90% of the frame. The camera intelligently switches between contrast and phase detection points to achieve precise focusing regardless of lighting conditions. Main features of the camera: 45.7MP FX format sensor without OLPF Continuous shooting at 9 FPS 64-25,600 ISO range UHD 4K 30p recording without FOV crop 10bit UHD 4K N-log output via HDMI with start/stop support 5-axis VR stabilisation (with Z-lenses) 8K time-lapse with exposure smoothing CF Express ready (currently supports XQD) Nikon Z6 Camera The Z6 is equipped with a 24.5 MP FX-format sensor that allows continuous shooting at up to 12 FPS and an ISO range of 100-51,200. Videos are recorded internally at up to UHD 4K 30p without cropping the field of view. 273 on-sensor focus points cover 90% of the subject and the Z 6 intelligently switches between contrast and phase detection points to ensure precise autofocus. Main features of the camera: 24.5MP FX-format sensor with OLPF 12 FPS continuous shooting ISO range 100-51,200 UHD 4K 30p recording without FOV crop 10bit N-log UHD 4K output via HDMI with start/stop support 5-axis VR stabilisation (with Z-mount lenses) 4K time-lapse CF Express ready (currently only XQD) The Nauticam NA-Z7V underwater housing Nauticam has produced a variety of housings for Nikon DSLR cameras and is not new to the mirrorless format. Nauticam has developed housings for full-frame, APS-C and MFT mirrorless cameras from various camera manufacturers. The NA-Z7V, just like Nikon's Z6/7 cameras, is an evolutionary step in underwater housings that seamlessly combine the Nikon F-mount and the new Z-mount in one housing. F- and Z-mount support The Nauticam NA-Z7V body not only allows the use of the new Z-mount Nikon glass, but also F-mount lenses with the Nikon FTZ adapter. This is crucial as the new Z-mount lenses will be phased in over the next few years. The Nauticam NA-Z7V body has two lens release buttons suitable for either F- or Z-mount lenses. When switching between F-mount and Z-mount lenses, the camera must be removed from the housing to remove the adapter. If you are using the F- or Z-mount system, use the appropriate lens release button to change the lens without removing the camera from the body. A vacuum reset switch is also located under the tray so that the back of the housing does not need to be opened when changing lenses or adapters. Intelligent operation Nauticam's engineers are obsessed with functionality, which is evident in the placement of the essential controls.  Regardless of where the controls are located on the camera, the Nauticam housing puts them where you need them underwater.  For those switching between photo and video modes, there is an easy-to-reach switch on the right rear of the housing.  The right double thumb lever, easily reached from the right grip, gives access to the AF-on or Record button.  Between the double thumb lever and the multi-step shutter release is an ISO lever that allows quick changes in sensitivity. The left double tick lever provides access to the DISP and playback controls.  The zoom in and zoom out controls on the right rear of the camera housing are on the left side of the housing and are in a location more familiar to Nauticam housing users. The switch that toggles between the LCD display and the electronic viewfinder, an important and widely used control with mirrorless systems, is within easy reach near the left grip.   Front and rear controls are easily accessible via the familiar large knurled wheels on the right handle.  The ergonomic housing handles are rubberised and feature stainless steel stiffening brackets to ensure a stable platform when using large strobes or video lights attached to the pre-installed 1-inch ball heads. Z7 mit 60mm Makro Flash release The NA-Z7 comes with Nauticam's self-powered manual flash trigger pre-installed.  The flash trigger plugs into the camera's hot shoe and uses LED lights inserted into each of the two optical bulkheads to trigger assisted underwater flashes when used with the correct fibre optic connector.  The flash trigger is powered by button cell batteries that provide thousands of flashes per battery.  The flash trigger can be upgraded to support TTL triggering (NA26308). HDMI video output The Z7 camera supports 10-bit HDMI video output with UHD resolution (3840 x 2160) at up to 30p.  An external monitor or recorder can be used with the optional standard M16 HDMI socket (NA25033), HDMI (D-C) cable in 190mm length (NA25036), which is included as standard in every Nauticam monitor housing. The NA-Z7V also has an M24 socket that supports HDMI 2.0 output.  Atomos and Nikon have announced that video output via HDMI 2.0 from the Nikon Z6 and Z7 can be captured in Apple ProRes RAW format on the Ninja V monitor/recorder.  Currently, footage can be recorded in high quality ProRes 4:2:2 10-bit 30p UHD 4K when used with the Ninja V using the Nauticam NA-Ninja V housing with HDMI 2.0 cable PN 25085.

Both the Canon EOS R5C and EOS R present shooters with the ability to use both the available legacy EF lenses via an adapter in addition to their native RF optics.  To support both the legacy and native lenses, Nauticam has integrated the NA-R5 into the N120 port system. Canon's EF to RF mount adapters can be affixed to the camera before insertion into the housing. When using the EOS RC5 inside the housing with the adapter and a supported EF lens, the port and extension ring arrangement will be identical to the same setup on a Nauticam Canon N120 DSLR. As the RF lens lineup emerges, dedicated port and extension ring combinations will be listed on the Port Chart. Two lens release buttons, one for RF and one for EF lenses used with the optional Canon adapter, are located on the front of the housing to make lens removal through the port opening simple. Mission Control Nauticam engineers are obsessed with getting the underwater image maker unfettered access to all the necessary controls, with as many within easy reach of the ergonomic rubberized handles. This Mission Control philosophy extends to the NA-R5C where a dual thumb lever and dual sub-lever are placed by the right handle. The upper thumb lever activates the "AF-On" and the lower the "Q" buttons while the sub-lever corresponds to the "M-Fn" and "Record" buttons. Near the left handle is a thumb lever for "Playback" as well as a dedicated switch to change from using LCD to the EVF. Large knurled and rubberized control dials access the camera's "main" and "sub" command dials. The two-stage trigger allows for smooth focus and firing activation. Additional buttons for "Menu", "Focus Point Selection" and others are also easily reached from the handles. An additional control wheel is located on the left side of the housing and will interface with the control ring on the supported EF to EOS R Mount Adapter with Control Ring using the optional gear (NA19561). Flash Triggering Flash triggering is achieved via one of two optional Flash Triggers, a manual LED trigger (NA26301) or a TTL Flash Trigger (NA26321) that use the built-in fiber optic bulkheads with optional fiber-optic cables to trigger supported strobes. For controlling strobes that do not support fiber optic flash triggering, a variety of legacy hot-shoe flash control bulkheads are available. INTEGRATED VACUUM CHECK AND LEAK DETECTION SYSTEM The Nauticam vacuum check and leak detection electronics are shipped with the NA-R5C as standard equipment. Combined with an accessory vacuum valve this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple color coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The Nauticam system is temperature compensated, eliminating false alarms caused by a change in outside temperature, or from a camera heating up on an action packed dive.

THE NIKON Z 50 CAMERA Nikon's Z Mount debuted with the Z 6 and Z 7 full-frame mirrorless cameras and is one of the widest lens mounts available in its class.  This wider mount allows for faster and more compact lens designs.  The Z 50 is equipped with a 20.9MP DX (APS-C) CMOS image sensor that is mated to their EXPEED 6 processor.  The Z 50 lists a native ISO range of 100-51,200 and has extensive Auto ISO controls spread across its operating modes.  4K UHD video is captured using the entire width of the sensor meaning no loss in the lens' field-of-view, a critical feature for the underwater video shooter.  HD video at up to 120fps allows for dynamic slow motion capture.  Switching between still and video is accomplished via a convenient switch on the rear of the camera and the Z 50 maintains discrete exposure settings for each mode.  This makes switching between video and still shooting even easier without having to make excessive setting changes. Key Camera Specs 20.9MP CMOS DX Format image sensor UHD 4K Video at up to 30p or HD at 120fps Twin control dials 2.36M-dot OLED Viewfinder 11fps continuous shooting Pop-up flash THE NAUTICAM NA-Z50 UNDERWATER HOUSING Nauticam's NA-Z50 is designed around the N100 Port System which is also used in the lineup of full-frame and APS-C mirrorless cameras such as the Sony A7r IV and Fujifilm X-T3.  The NA-Z50's form-fitting style and intuitive control placement make the system ideal for the traveling photographer that demands a reliable and portable underwater imaging platform. MISSION CONTROL Nauticam's driving design philosophy aims to place controls on the housing where they are most needed.  The NA-Z50 features molded ergonomic handles with stainless steel stiffening brackets that eliminate wobble when using large strobes.  The main and sub command dials are accessed via large textured knobs within easy reach of the right handle.  The Nauticam patented multi-direction pad makes menu navigation or autofocus point movement seamless.  A double thumb-lever, easily pressed without removing your hand from the right grip, activates the AF-ON and REC buttons on the camera.  A thumb lever near the left handle is for PLAYBACK.   For video shooters, the Nikon Z50 maintains separate exposure settings in Still and Video modes and switching between the modes is done via a convenient switch which is easily accessed on the top of the NA-Z50 housing.  With extensive Auto ISO controls, the NA-Z50 is an ideal platform to create video content with the Z 50's UHD 4K 30p or HD 120p capture. FLASH TRIGGERING The Nikon Z 50 has a pop-up flash that can be used to provide accurate TTL flash triggering using the integrated fiber-optic bulkheads.  A switch on the housing allows the flash to be raised or lowered to allow quick switching between ambient and artificial light shooting.  To reduce refresh time and extend the camera's battery life, the NA-Z50 can be outfitted with the optional TTL Converter for Nikon (26308).  Operating off of two coin-cell batteries and interfacing via a hot-shoe connection to the camera, the TTL Converter uses LEDs to deliver a TTL signal to external strobes.   PREMIUM PROFESSIONAL OPTICS Nikon continues to increase their Z Mount lens lineup and the Z 50 is the first DX format camera to feature the larger mount.  Nikon's first lens for the system, the stabilized Nikkor Z DX 16-50mm F3.5-6.3 VR lens is ideal for underwater use when paired with Nauticam's water contact optics lineup.  Compatible with both the WWL-C and WWL-1* wide angle conversion lenses, this combination delivers full zoom-through capabilities with a stunning 130º field-of-view and ~0" minimum focus distance.  Using Nauticam's Bayonet Mount system, the WWL-C or WWL-1 can be swapped for either the CMC-1 or CMC-2 underwater, converting the system to capture true macro and super-macro.  When using full-frame (FX) or APS-C (DX) F mount lenses via the Nikon FTZ Adapter with the NA-Z50, the 35.5mm N100 to N120 Port Adapter (37305) is used in conjunction with the corresponding N120 Port recommendations for those lenses. * no vignetting at 20mm onwards with WWL-1B VIEWFINDER OPTIONS The Nikon Z50 has 2.36M-dot OLED viewfinder.  The NA-Z50 is compatible with Nauticam's magnifying viewfinders which are available in both 45º and 180º configurations.  The standard optical glass viewfinder is very good and travel friendly, but many photographers prefer the ease of a magnified viewfinder with adjustable diopter. Nauticam produces a "straight" 180º enlarging viewfinder and a 45º angled enlarging viewfinder to enhance the ease of close quarters work often associated with macro shooting. Both viewfinders have high quality optics, and allow bright viewing of the entire image. A patented external dioptric adjustment allows personal adjustment to a sharp-as-a-tack standard underwater and viewfinder changes can be executed in less than 30 seconds without using tools. Exceptional composition and focus accuracy have never been more accessible. INTEGRATED VACUUM CHECK AND LEAK DETECTION SYSTEM The Nauticam vacuum check and leak detection system is shipped with NA-Z50 as standard equipment. Combined with an accessory vacuum valve (PN 25625), this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple color coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The Nauticam system is temperature compensated, eliminating false alarms caused by a change in outside temperature, or from a camera heating up on an action packed dive.

The long awaited Sony a7S III brings high frame-rate 4K video with incredible low-light sensitivity to the A7 full frame mirrorless lineup. The video-centric follow up to the a7S II adds internal 10-bit 4:2:2 4K capture at up to 120fps while building on the a7S II's already segment leading low-light capabilities. Upgrades also extend to the 9.44M dot OLED viewfinder, 759-point phase detection autofocus and reduced rolling shutter. THE SONY ALPHA  A7S III CAMERA Built around a new 12.1MP Exmor RS BSI CMOS sensor coupled with a BIONZ XR image processor, the a7S III is a powerful video oriented mirrorless full-frame camera. The long awaited follow up to the a7 SII, which set the standard for low-light capabilities in the full-frame mirrorless segment, brings not only improvements to that key spec but also a host of other notable upgrades. Key Camera Specs 12.1MP Exmor RS BSI CMOS sensor ISO sensitivity of 40-409600 4K Video Capture at up to 120fps Internal recording at up to 10-bit 4:2:2 color sampling No recording time limit 16-bit raw video output over HDMI-A 759-Point phase-detection autofocus with 92% coverage Dual UHS-II card slots S-Log2/3 or HLG/BT.2020 gamma curves 5.5 Stop IBIS The new sensor features 759 phase-detection and 425 contrast-detection autofocus points that cover approximately 92% of the image area and promises sensitivity down to -6 EV.

A 5-axis in-body stabilization system provides 5.5 stops of camera movement, even with adapted lenses, which combined with the 120fps frame-rates help deliver ultra-smooth handheld video. Video can be recorded in either All-I XAVC S-I at up to 600Mbps or XAVC HS which uses H.265 compression for smaller file sizes. Internal 4K recording uses 1:1 pixel readout at up to 120fps with 10-bit 4:2:2 sampling. The a7S III offers extensive color customization including the S-Log2 and S-Log3 gamma curves that can deliver 15+ stops of dynamic range. HLG and BT.2020 color spaces are also available. Recording time limits have been removed and improved heat dissipation has been added to the camera body's design. Internal recording is to UHS-II rated dual card slots that support CFexpress Type A or SD cards. External recording of 16-bit raw video is possible via the full size HDMI port when used with compatible Recorders. NAUTICAM NA-A7SIII UNDERWATER HOUSING Nauticam is the leader in producing intuitively designed precision manufactured aluminum underwater housings for the Sony a7 camera line and continues to innovate with the new NA-A7SIII housing.  The NA-A7SIII is designed to maximize the video-centric capabilities of the Sony a7S III camera while maintaining it's strong still image potential.  The NA-A7SIII is built around the N100 port system that is shared with the rest of the Nauticam housing lineup for the Sony full-frame mirrorless a7 series.  The N100 system includes a dull range of both macro and wide-angle ports as well as delivering access to the lineup of Nauticam's professional wet optics that are optimized for underwater imaging such as the WACP-1/2 and the SMC-1/2 lenses.  These optics deliver unparalleled image quality underwater expanding what is possible with the powerful a7S III camera. HDMI Output The a7S III can output 16-bit raw video signal over HDMI and the NA-A7SIII features an M24 bulkhead that supports the HDMI 2.0 standard.  This allows the NA-A7SIII to be used in conjunction with either a recording monitor such as the Atomos Ninja V in the NA-NinjaV housing  via HDMI 2.0 or standalone monitors such as the SmallHD 502 Bright in the NA-502B housings via HDMI 1.4.   Optional Magnifying Viewfinder The a7S III camera features an updated 9.44M-dot OLED viewfinder with a 120fps refresh rate.  Nauticam's line of optional magnifying viewfinders, available in both an angled 45º (32203) or straight 180º (NA32201) configuration provide enhanced viewing ability as well as a dioptric adjustment knob that can used underwater.  Installation can be achieved without tools in less than a minute.   Mission Control Nauticam engineer's Mission Control design philosophy means controls are intuitively placed where they are needed most regardless of their position on the camera.  The NA-A7SIII features a double thumb lever within easy reach of the right handle that triggers the AF-ON and RECORD controls of the camera.  A thumb lever on the left side toggles the PLAYBACK button.  The back panel of the housing provides access to all other rear camera controls including a multidirectional pad. Vacuum Check and Leak Detection System The Nauticam vacuum check and leak detection system is shipped with NA-A7SIII as standard equipment. With the addition of the optional M14 Vacuum Valve (NA25624) this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple color coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The Nauticam system is temperature compensated, eliminating false alarms caused by a change in outside temperature, or from a camera heating up on an action packed dive.

The Z 7II and Z 6II, Nikon's next generation full-frame mirrorless cameras, offer underwater shooters the same legendary Nikon sensors with improved autofocus and continuous shooting speed performance. The NA-Z7II supports both the Z 7II and Z 6II models and features the larger-bore M28 bulkhead that supports HDMI 2.0 connections needed for the Atomos Ninja V Recorder/Monitor. THE NIKON Z 6II AND Z 7II CAMERAS For many full-frame Nikon shooters the appeal of a mirrorless camera had been tempered by the thought of having to invest in and master a new system by moving to another ecosystem such as Sony. For those awaiting a mirrorless system that utilized Nikon imaging technology and ergonomics, the wait is over. The Z 6II and Z 7II cameras feature an identical body, differing only in their feature sets, an ideal feature when it comes to housing the camera for underwater use.  Each camera also features dual EXPEED 6 image processor to significantly improve autofocus and continuous speed shooting.   Both camera bodies are built around Nikon's Z-mount. With an incredibly wide 55mm mount diameter (17% larger than F-mount) and very short flange distance, the Z-mount is able to offer a maximum aperture of F0.95. While the current range of Z-mount lenses continues to grow, almost the entire line of F-mount lenses is usable with the optional Nikon FTZ Adapter. When using the adapter, even non VR lenses benefit from the camera's in-body stabilization. VR and Z-Mount lenses receive 5-axis stabilization whereas non-VR F-mount lenses have access to 3-axis stabilization. There is also a dedicated e-VR (electronic VR) that combines optical and electronic stabilization for video shooting. Both the Z 6II and Z 7II will be able to capture internal UHD 4K at 60fps or 1080 HD at up to 120fps.  The Z 6II will be able to record 4K/60P early in 2021 through an expected firmware update.  In addition to N-Log, both cameras also feature HLG (hybrid-log gamma for HDR) which work in 10-bit 4:2:2 over HDMI 2.0 to an external recorder such as the Ninja V.   The OLED electronic viewfinder (EVF) of both the Z 6II and Z 7II gives 100% frame coverage at Quad-VGA (3.69M dot) resolution. When triggering external flashes, both cameras feature a 1/200 X-sync shutter speed. THE NIKON Z 7II CAMERA The Z 7II features a high resolution 45.7MP FX-format sensor that can shoot at up to 10FPS. The Z 7II features a wide ISO range of 64-25,600. Autofocus is achieved with 493 on-sensor AF points that cover 90% of the frame and the camera intelligently switches between contrast-detection and phase-detection points to achieve accurate focus regardless of light conditions. KEY CAMERA SPECS: 45.7MP FX Format Sensor with no OLPF 10 FPS continuous shooting 64-25,600 ISO Range UHD 4K 60p recording with 1.08x crop 10bit UHD 4K N-log output via HDMI with start/stop support 5-axis VR stabilization (with Z lenses) 3.69M-dot EVF, 3.2" 2.1M-dot rear screen -3EV focusing with F2.0 lens 1 CFExpress / XQD card slot, 1 UHS-II SD card slot THE NIKON Z 6II CAMERA The Z 6II is equipped with a 24.5MP FX-format sensor capable of up to 14FPS continuous shooting with an ISO range of 100-51,200. Video is currently recorded internally at up to UHD 4K 30p.  UHD 4K 60p with a 1.6x crop will be available in early 2021 through a firmware update. 273 on-sensor focus points cover 90% of the fame and the Z 6II intelligently switches between contrast-detection and phase-detection points to assure accurate autofocus.

Both the Nikon Z 6II and Z 7II present shooters with the ability to use both the available legacy F Mount lenses via the FTZ adapter in addition to their native Z Mount optics.  To support both the legacy and native lenses, Nauticam has integrated the NA-Z7II into the N120 port system.  This is critical as the new Z mount lenses are being phased in over the next few years. The Nauticam NA-Z7II housing features two lens release buttons that correspond to either F or Z mount lenses. When switching between F and Z mount lenses, the camera must be removed from the housing to remove the adapter. When working within either the F or Z mount system use the appropriate lens release button to switch lenses without having to remove the camera from the housing. A vacuum system reset switch is located below the tray as well so there is no need to open the rear of the housing during lens or port changes. The NA-Z7II is part of the N120 port system which allows for full support of Nikon F mount lenses with the same ports needed for their application on Nikon SLR housings. As more Z mount lenses become available Nauticam will add supported configurations. INTELLIGENT CONTROL PLACEMENT Nauticam engineers are obsessed with functionality and this is evident in the location of essential controls. Regardless of where the control is located on the camera, the Nauticam housing puts them where you need them to be underwater. For those switching between photo and video modes, an easily reachable switch is located on the right rear of the housing. The right side double thumb lever, easily reached from the right handle features access to the AF-on and Record buttons respectively. Between the double thumb lever and the multi-stage shutter release is an ISO lever allowing quick changes to sensitivity. The left double thumb lever accesses the DISP and Playback controls. The Zoom In and Zoom Out controls, located on the right rear of the camera body is relocated to the left side of the housing to a location more familiar to Nauticam housing users. The switch that allows for switching between the LCD display and the EVF, a crucial and much used control with mirrorless systems is located close to the left handle within easy reach. Front and rear control dials are readily accessible by the familiar large knurled dials at the right handle. The ergonomic housing handles are rubberized and feature stainless steel stiffening brackets to ensure a stable platform when using large strobes or video lights attached to the pre-installed 1" mounting balls. FLASH TRIGGERING The NA-Z7II comes with Nauticam's self powered manual flash trigger preinstalled. The flash trigger plugs into the hot-shoe of the camera and uses LED lights recessed into each of the two optical bulkheads to trigger supported underwater flashes when used with the correct fiber optic connection. The flash trigger is powered by coin cell batteries that provide thousands of flashes per battery. The flash trigger can be upgraded to support TTL triggering (PN 26308 TTL Converter for Nikon). INTEGRATED VACUUM CHECK AND LEAK DETECTION SYSTEM The Nauticam vacuum check and leak detection system is shipped with NA-Z7II as standard equipment. Combined with an accessory M16 vacuum valve (PN 25625), this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple color coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The Nauticam system is temperature compensated, eliminating false alarms caused by a change in outside temperature, or from a camera heating up on an action packed dive. PREMIUM PROFESSIONAL OPTICS Optical performance is just as necessary as camera performance and this becomes even more critical given the challenges of filming underwater. The Nauticam NA-Z7II uses the same N120 Port System as the previous NA-Z7 which makes for a seamless transition for those upgrading to the "II." While this system provides exceptional optical-glass and flat port solutions for a wide variety of F and Z Mount lenses, the real power of the Z 6II and Z 7II can be realized using Nauticam's Water Contact Optics. This lineup of dry and wet lenses are conceived using commercial lens-design software to achieve truly unparalleled underwater image quality both for stills and video in both macro and wide-angle situations. The WACP-1 and WACP-2 achieve ultra-wide 130º fields-of-view with reduced distortion over conventional optics while featuring ~0" minimum focus distances, zoom through capabilities and unbeatable corner sharpness at even wide-open apertures such as F5.6. The SMC-1 and SMC-2 macro wet-optics, when used with the Nikon 105mm f/2.8G VR macro lens provide 2x and 4x magnification respectively and the SMC-1 actually provides a resulting image with increased contrast and sharpness than the 105mm lens itself can achieve in air without a magnifier.

THE CANON EOS R3 CAMERA The Canon EOS R3 in all respects appears to be the mirrorless sibling of the 1DX Mark III DSLR, clearly aimed at fulfilling many of the same roles while offering some additional capabilities through the use of the electronic viewfinder and the larger RF lens mount.  The full-frame 24.1MP Stacked CMOS sensor, in addition to having incredible low-light performance, can also capture full-width 6K video in both Raw and compressed formats at up to 60fps.  The R3 is paired to Canon's industry leading Dual Pixel AF system with 100% frame coverage and the now revived Eye AF system. DUAL PIXEL AF II Canon's Dual Pixel autofocus system has long been a favorite of underwater users, especially when it comes to tacking subjects.  With the R3, the system adds an additional 'Animal' recognition mode which might make the system even more reliable at following moving subjects.  Frame coverage is 100% with 1053 zones to ensure accurate focus wherever the subject may be. LOW LIGHT PERFORMANCE The ability to increase a camera's ISO with little penalty is of critical importance to underwater shooters for both stills and video as shooting with higher F-stop values delivers sharper corners and higher shutter speeds mean less motion blur.  The higher video frame rates also benefit by allowing the shooter to maintain a 180º shutter while still maintaining adequate aperture values.  When using color correction filters, which can often remove more than a full stop of light, compensation via ISO is not as much of an issue for overall image quality.  Maintaining dynamic range, even at high ISO levels is also important for those shooting still images using natural light or in poor water conditions. ENHANCED CONTROLS The R3 features an additional control wheel located at the upper right rear of the camera which doubles as the mode control.  This wheel can be assigned a variety of functions such as ISO and is adjusted by a dedicated control wheel on the housing within easy reach of the right handle.   VIDEO CAPABILITIES The Canon R3 can capture 6K video at up to 60fps in either Raw or more compressed formats.  The 6K capture uses the full sensor width which means no loss in field-of-view.  12-bit 6K capture is possible in both uncompressed Canon Raw or compressed Raw light formats.  10-bit H.265 is also possible in both the HDR PQ and Canon Log3 gamma curves to maximize dynamic range for post processing while maintaining smaller file sizes than a Raw format.  It's also possible (when using supported cards) to simultaneously record 10-bit 4:2:2 DCI 4K 60p video.  For those looking for higher frame rates, 10-bit 4:2:2 compressed 4K/120fps can also be captured, downsampled from the full sensor width.  A natively sampled 4K S35 crop is also an option, allowing for more magnification or the use of APS-C lenses.  The R3 also outputs a clean 6K signal over HDMI via an HDMI Micro Type D connector.  Direct custom white balance in live view is also now possible, making a critical function for underwater video even easier. STABILIZATION The R3 features 5-axis In Body Image Stabilization (IBIS) which can offer up to 8 stops of correction allowing for even smoother video and less camera movement related blur. LARGE ELECTRONIC VIEWFINDER The R3's EVF is an OLED 5.76M-dot that features an OVF simulation mode which leverages. the large dynamic range of the OLED screen to reproduce a scene the way it would look through an optical viewfinder.  The lower dynamic range of electronic viewfinders has always made them more difficult to use underwater, especially in high contrast or backlit scenes. This function can easily be switched on and off by assigning it to a custom function button.  When using the Electronic Shutter, which has an X-Sync speed of 1/180sec, the EVF delivers true no-blackout shooting up to 30fps.   Example setup THE NAUTICAM NA-R3 UNDERWATER HOUSING The Nauticam NA-R3 professional aluminum underwater housing for the Canon EOS R3 mirrorless full frame camera is a tru hybrid shooting solution, just as the R3 itself.  Nauticam has continuously supported both the Canon pro-level DSLR lineup as well as the growing full-frame RF-mount mirrorless cameras with innovative underwater housings and the new NA-R3 is the combination of all those technologies.  Blending elements of our 1D series housings with those for the R series, the NA-R3 will be the most capable housing for the R3 available. MISSION CONTROL Nauticam engineers design each housing to insure that controls are placed where they are needed most and within easy reach of a natural hand position.  The NA-R3 features large knurled control dials for the main and sub-command dials as well as an additional shoulder dial for the customizable control wheel of the R3.  A fourth control wheel, near the front of the left handle can articulate the ring of the optional EF-to-RF lens adapter when using EF lenses.  There is a dual thumb lever on the right side for Record and AF-ON as well as single levers for M-Fn and Fn2.  A lever on the left side actuates the Pv control which can change between exposure preview and OVF simulation modes on the EVF.  An additional dual thumb lever on the left side is for Playback and Magnification. HDMI 2.0 AND MOUNTING POINTS The R3 can output clean 6K 60p over HDMI and the NA-R3 features a large bore M24 bulkhead to support an HDMI 2.0 connection to an external monitor or recorder.  Mounting the monitor or recorder or other accessories is even easier with 3x 1/4"-20 mounting holes as well as an additional M10 mounting point atop the housing.  Check the resources sidebar for supported monitor/recorder housings and recommended accessories. FLASH TRIGGERING Flash triggering can be accomplished via the two included M14 electronic bulkheads (One is pre-installed in the M24 bulkhead via a removable M26-M14 adapter).  If using fiber-optic triggering, the built-in fiber optic bulkheads can be used with either the optional manual LED or TTL-flash triggers to provide the desired type of strobe power control. PREMIUM PROFESSIONAL OPTICS The NA-R3 is built around the N120 Canon RF-mount Port System which supports a wide array of Canon RF mount lenses with a selection of optical glass and acrylic ports.  With lens-removal controls for both EF and RF mount lenses, the NA-R3 can support both lens mount types without modification to the housing.  The EF-RF lens adapter is accommodated inside the housing which allows for the use of the N120 Canon EF-mount Port System without any additional extension rings.  When switching between an EF and RF lens, the camera must be removed to install or remove the adapter.  The Nauticam lineup of Premium Professional Optics can deliver unparalleled optical quality and expanded creative options. When used with the Canon RF 14-35 F/4 IL USM lens, the WACP-2 creates a stunning 140º field-of-view while maintaining an incredibly natural looking image and excellent corner sharpness.  The SMC-1 delivers 2.3x macro magnification to the RF 100mm macro lens while the SMC-2 delivers 3.3x. VACUUM CHECK AND LEAK DETECTION SYSTEM The housing comes with electronics pre-installed for Nauticam's Vacuum Check and Leak Detection system, requiring only the optional M16 Vacuum Valve (25625). This monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple color coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The Nauticam system is temperature compensated, eliminating false alarms caused by a change in outside temperature, or from a camera heating up on an action packed dive.

THE NIKON Z9 MIRRORLESS FULL FRAME CAMERA Nikon's Z9 takes a divergent step from similar top-level mirrorless full frame systems from Sony and Canon by removing the mechanical shutter altogether. This departure, along with the powerful processor allow for the true no-blackout or 'Real-Live" electronic viewfinder (EVF). With a maximum 3,000nit brightness, the EVF promises an even more natural viewing experience similar to an optical viewfinder. The 'F3' button comes pre-set to remove all overlay data from the EVF for an unobstructed composition-focused workspace.  The Z9 is built around a 45.7MP stacked CMOS sensor with exceptional low light performance and 14-bit raw image capture.  The ISO range of the Z9 is 64 to 25,600 with expansion possible to 32-102,400.  The EXPEED 7 processor features advanced noise reduction to maximize image quality at even higher ISO values. AUTOFOCUS Nikon's autofocus has seen dramatic improvement with the Z series and Z9 continues that evolution with AF that works all the way down to -8.5EV (with supported lenses) and features advanced 3D subject tracking. Furthermore, the subject detection system can be set to auto-select the subject type such as animals or people. With over 400 points into auto-detect area, this is sure to deliver exceptional tracking across the frame. 8K VIDEO The EXPEED 7 processor also allows for 8K UHD 30p internal recording with advanced heat dissipation to prevent overheating with an 8K/60P Raw recording firmware update coming in 2022. 10-bit 4K UHD can also be recorded with full pixel readout or with a 2.3x crop factor, exceptional for getting even more macro magnification. The future firmware update will add 12-bit 8K/60p in either Nikon's RAW format or ProRes RAW HQ.  Internal recording is available in either H.265 (8-bit), H.265 (8,10-bit) or ProRes HQ 422 (10-bit) formats to support different workflows.  The Z9 is equipped with dual CFexpress Type-B card slots that also accommodate XQD media. THE NAUTICAM NA-Z9 UNDERWATER HOUSING The Nauticam NA-Z9 brings embodies the experience gained by producing professional housings for Nikon's flagship DSLR and mirrorless cameras, blending them to create the most intuitive underwater imaging platform available. F AND Z MOUNT COMPATIBLE The NA-Z9 uses the N120 Port System for Z-Mount full-frame lenses. When using F-mount lenses, the FTZ adapter is inside the housing which allows for the same port configuration as is found on an F-mount DSLR system such as the NA-D6 or NA-D850. Convenient lens release buttons on the housing for both F and Z mount makes lens changes a snap regardless of platform without having to remove the camera from the housing; only when installing or removing the FTZ adapter.

With the ability to accommodate both Panasonic LUMIX S1 and Panasonic S1R cameras, the Nauticam NA-S1R housing offers tremendous versatility to the underwater photographer. Nauticam's drive for innovation and focus on real-world usability is clearly reflected in the NA-S1R's features.   Although the two cameras may have different strengths, the NA-S1R is designed and built to give both video and photography enthusiasts easy access to all the controls and functions, exactly where they need them. Operation Nauticam engineers are obsessed with ease of use, and the Mission Control philosophy means they place essential controls where they are needed, regardless of where they are on the camera body. By placing the controls as close as possible to the handles and within easy and natural reach, users can concentrate on the composition and timing of their shot while adjusting exposure or focus without taking their eye off the viewfinder or screen.   The NA-S1R has a double thumb lever on the left rear of the body that accesses DISP and playback, while a double thumb lever on the left front activates the customisable Fn1 and Fn2 buttons.  A rear thumb lever on the right side is for AF-On and REC.  A lever on the right side of the NA-S1R allows the focus mode to be switched between C/S/MF and a multi-directional pad that provides the ability to navigate through the menu or move the focus point. Sigma EF lens support The MC-21 EF to L adapter from Sigma allows the use of Sigma EF lenses for use with the S1 and S1R cameras. The NA-S1R underwater housing is designed to not only accommodate the adapter, but also to allow the use of the existing focus and zoom wheels for Sigma lenses with Canon mounts, as well as the existing extension ring and port combinations for these lenses.     Flash release Optical flash triggering with automatic exposure (TTL) is supported by the Panasonic DMW-FL70 clip-on flash (sold separately). For quick manual flash triggering, the NA-S1R is compatible with the Nauticam Mini Flash Trigger (NA26309), which uses small LED units to trigger external flashes via Nauticam Universal Fibre Optic (26216).  A TTL flash on/off switch on the top of the housing allows the DMW-FL70 flash unit to be activated or deactivated in water.  HDMI 2.0 output To take full advantage of the S1's video capabilities, the NA-S1R features the large-size M28 connector for HDMI 2.0 connections, such as those used on the Atomos Ninja V in conjunction with the Nauticam Atomos Ninja V housing (HDMI 2.0). Vacuum testing and leak detection system The Nauticam vacuum testing and leak detection system is supplied with NA-S1R as standard. Combined with an additional vacuum valve (NA25625 or NA25624), this monitoring system provides constant information about the watertight and submersible condition of the enclosure. A simple colour-coded LED lighting system indicates to the user that the vacuum is tight or that the enclosure is losing vacuum. Leak detection is integrated into the same circuit so that an audible and visual indication is given in the event of water ingress.  The Nauticam system is temperature compensated and eliminates false alarms caused by a change in outside temperature or a camera heating up during an action-packed dive.

Sony has been at the forefront of the mirrorless evolution, offering cameras with specifications that are truly geared towards meeting the disparate needs of today's image makers while maintaining a similar, if not almost identical form factor. With the a7R IV, Sony introduced the highest resolution full frame mirrorless camera to date and with the a9 II it took speed image quality to another level. Luckily, for those wishing to take their cameras underwater, the a7R IV and the a9 II have extremely similar body size and control placement. For this reason, Nauticam is offering the NA-a2020 housing that offer full support for both cameras in the same housing without modification. THE SONY A7R IV AND SONY A9 II CAMERAS While both the a7R IV and the a9 II feature the same size sensor and body, they are two very different cameras. With the NA-a2020 Underwater Housing, you now can choose the right camera for the job while using the same housing, lenses and ports. Both cameras share 5-axis in-body stabilization (IBIS) providing up to 5.5 stops of stabilization and the ability to record 4K video either from the full sensor width or a Super35 crop at up to 30p to dual UHS-II SD card slots. Both cameras are capable of clean HDMI video output up to UHD 4K 4:2:2 8-bit at up to 25p. THE SONY A7R IV CAMERA The Sony a7R IV is the company's fourth generation, high-resolution full-frame mirrorless camera. The 61.0-megapixel full-frame Exmor R CMOS sensor combined with BIONZ X imaging engine delivers unprecedented resolution, fine gradation, and low noise. Relative to previous generations, it promises more robust build quality, refined controls, the company's latest autofocus. The a7R IV also received a serious upgrade from a7R III to its electronic viewfinder (EVF) in a 1.6x bump in resolution to an impressive 5.76-million-dots of UXGA OLED display, the highest of any mirrorless full-frame camera. Sony Alpha a7R IV Key Specifications 61MP BSI CMOS full-frame sensor Fast Hybrid AF with tracking 10 fps burst shooting (12-bit Raw mode) with AF Tracking 5.76M dot OLED viewfinder 4K video from full sensor width (sub-sampled) or oversampled from Super35 crop S-Log 2, S-Log 3 and 'HLG' video modes (8-bit only) THE SONY A9 II CAMERA The a9 II is the flagship full-frame mirrorless camera in Sony's lineup and features a 24.2MP Exmor RS BSI CMOS sensor. The original a9 set the bar for high speed shooting with an incredible 20fps without EVF blackout, a trait passed on to the a9 II. It's 693 phase-detection pints cover over 93% of the sensor's surface which, combined with the BIONZ X processor leads to fast and accurate autofocus, even while tracking. Placing only 24.2 megapixels on the sensor, the a9 II prioritizes dynamic range and excellent low-light sensitivity over resolution. Sony Alpha a9 II Key Specifications 24.2MP BSI CMOS full-frame sensor 20fps continuous shooting without EVF blackout Fast Hybrid AF with Tracking 3.69M dot OLED viewfinder 4K video from full sensor width (sub-sampled) or oversampled from Super35 crop THE NAUTICAM NA-?2020 UNDERWATER HOUSING Nauticam has supported the Sony Alpha full-frame line since the original a7 with professional grade aluminum housings that offer intuitive access to all the controls and functions of the cameras. As the cameras have evolved, so have the Nauticam housings. The Nauticam NA-a2020 takes our commitment to the Sony full-frame mirrorless line to another level by delivering the first housing that will support both the a9 II and the a7R II with full access to all controls without modification or restriction. Integrated DSLR-housing styled handles with ergonomic rubberized grips and stainless steel stiffening brackets add stability and accessory mounting points. The NA-a2020 also features dual rear thumb-levers that are easily reached from the handle that access three of the most-used controls on the rear of the camera. The right lever actuates the AF-ON and RECORD buttons while the left lever is mapped to the PLAY button. Atop the housing on the left side are controls specific to the a9II in the form of a MODE dial and FOCUS mode lever. The C1, C2 buttons as well as the EV compensation dial also have direct access from the top of the housing. The C3, which is typically assigned to control switching between the EVF and the LCD screen is easily reachable on the rear of the housing from the left handle. ACCESSORY PORTS The NA-a2020 has both and M24 port at the front of the housing for both HDMI 1.4 and HDMI 2.0 connectivity (see sidebar for recommendations) as well as an M14 at the rear for the optional Vacuum Valve (25624). The housing comes with electronics pre-installed for Nauticam's Vacuum Check and Leak Detection system. This monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple color coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The Nauticam system is temperature compensated, eliminating false alarms caused by a change in outside temperature, or from a camera heating up on an action packed dive. PREMIUM PROFESSIONAL OPTICS Nauticam's wide range of ports and in-house corrective optics are the perfect compliment to the NA-a2020's inherent flexibility. Built around the N100 Port System, the NA-a2020 supports a wide variety of Sony FE mount lenses, as well as EF mount lenses via adapters. In addition, there are several options available to use the groundbreaking WACP and WACP-2 wide-angle corrective lenses as well as the more compact and in-water removable WWL-1. For example, With the Sony SEL1635GM FE 16-35mm F2.8 GM, the WACP 2 brings the original 105º field-of-view to an impressive 128º with sharper corners, an ~0" minimum focus distance and a more natural looking image than would be provided by a standard glass dome port. FLASH TRIGGERING Both fiber-optic and electrical strobe triggering options are available. The Nauticam Universal Fiber Optical cables attach to the built-in bulkheads atop the housing and feature modular connections for both Sea&Sea-style bushings and INON threaded connections. Triggering is achieved using the optional Nauticam Mini Flash Trigger for Sony (26302) which uses LEDs powered by an on-board coin-cell battery to generate a manual signal that is transmitter via the optical cables to compatible strobes.

THE CANON EOS R5 CAMERA The Canon EOS R5 is the latest in Canon's full-frame mirrorless camera lineup which has gained unprecedented demand.  It features the RF lens mount which has the same large 54mm diameter but the ability to have larger rear lens elements that are closer to the sensor gives increased corner and outer edge sharpness.  The R5 uses an all new 45MP CMOS sensor with in-body image stabilization which can reduce shake by up to 8 stops.  The camera's Dual Pixel autofocus system uses 1053 autofocus points across the entire frame.   It is also capable of recording 8K video at 24p or 30p and 4K at up to 120p.   The EOS R5 can also use the large EF-mount lens lineup via three optional adapters, a simple EF to R adapter, one which supports the customizable control ring and another that features a drop-in filter mount.

Both the Canon EOS R5 and EOS R present shooters with the ability to use both the available legacy EF lenses via an adapter in addition to their native RF optics.  To support both the legacy and native lenses, Nauticam has integrated the NA-R5 into the N120 port system. Canon's EF to RF mount adapters can be affixed to the camera before insertion into the housing. When using the EOS R5 inside the housing with the adapter and a supported EF lens, the port and extension ring arrangement will be identical to the same setup on a Nauticam Canon N120 DSLR. As the RF lens lineup emerges, dedicated port and extension ring combinations will be listed on the Port Chart. Two lens release buttons, one for RF and one for EF lenses used with the optional Canon adapter, are located on the front of the housing to make lens removal through the port opening simple. Mission Control Nauticam engineers are obsessed with getting the underwater image maker unfettered access to all the necessary controls, with as many within easy reach of the ergonomic rubberized handles. This Mission Control philosophy extends to the NA-R5 where a dual thumb lever and dual sub-lever are placed by the right handle. The upper thumb lever activates the "AF-On" and the lower the "Q" buttons while the sub-lever corresponds to the "M-Fn" and "Record" buttons. Near the left handle is a thumb lever for "Playback" as well as a dedicated switch to change from using LCD to the EVF. Large knurled and rubberized control dials access the camera's "main" and "sub" command dials. The two-stage trigger allows for smooth focus and firing activation. Additional buttons for "Menu", "Focus Point Selection" and others are also easily reached from the handles. An additional control wheel is located on the left side of the housing and will interface with the control ring on the supported EF to EOS R Mount Adapter with Control Ring using the optional gear (NA19561). Flash Triggering Flash triggering is achieved via one of two optional Flash Triggers, a manual LED trigger (NA26301) or a TTL Flash Trigger (NA26321) that use the built-in fiber optic bulkheads with optional fiber-optic cables to trigger supported strobes. For controlling strobes that do not support fiber optic flash triggering, a variety of legacy hot-shoe flash control bulkheads are available. Integrated vacuum check and leak detection system The Nauticam vacuum check and leak detection electronics are shipped with the NA-R5 as standard equipment. Combined with an accessory vacuum valve this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple color coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The Nauticam system is temperature compensated, eliminating false alarms caused by a change in outside temperature, or from a camera heating up on an action packed dive.

With the GFX100S, Fujifilm has transferred the power of the larger medium-format GFX100 into a smaller camera body that is more in line with a standard mirrorless full-frame cameras while also making various performance improvements.  The GFX100S maintains the 102MP BSI CMOS sensor yet features a smaller and lighter in-body image stabilization system, autofocus points that cover virtually 100% of the image frame and is powered by the X-Processor 4 chip. THE FUJIFILM GFX100S CAMERA Fujifilm's mirrorless medium-format (44mm x33mm sensor size) GFX100S camera packs the expected large 102MP pixel count into a camera body more in-line with a full-frame mirrorless system.  Even while reducing overall camera size, the GFX100S receives a more capable in-body image stabilization (IBIS) system as well as supercharged autofocus driven by the latest X-Processor 4 chip.  Key Camera Specs 102MP BSI CMOS Sensor (44mm x 33mm) IBIS rated at 6EV 4K 30p video at up to 400Mbps with full-width readout Uncompressed 10-bit 4:2:2 or 16-but raw video output over HDMI Dual-gain ISO Up to 16-bit uncompressed raw files The GF-mount lens lineup continues to grow, with more and more lenses meeting the criteria underwater image-makers are after.  Paired with the camera's medium-format 102MP sensor, which is 68% larger than a full-frame sensor, the resulting images have lower noise and greater dynamic range for a given exposure value.  Users can choose to record up to 16-bit uncompressed raw image files, preserving the maximum amount of sensor data for post-processing. The GFX100S features the latest X-Processor 4 chip which powers the improved autofocus system that covers virtually 100% of the image area.  The camera's large built-in OLED viewfinder has 3.69M-dot resolution at 0.77x magnifications and features variable refresh rates and resolution to enhance battery life. Video from the GFX100S uses the full sensor width, preserving the original field-of-view of the lens and can be recorded internally as 4K 30p video with a bit-rate of up to 400Mbps.  Over HDMI the GFX100S can output either an uncompressed 16-bit raw or 10-bit 4:2:2 4K video signal, excellent news for those using external monitors/recorders such as the Atomos Ninja V.   With dedicated settings for both still or video modes, switching between shooting modes is quick and easy via a lever atop the camera.  The camera's "Q" menu can be customized to provide the most valuable information as either an overlay on the live-view representation or as the entire LCD area.   Example-Setup The Nauticam NA-GFX100S Underwater Housing  The NA-GFX100S is built with the singular focus of creating an underwater housing that blends ergonomic design, intuitive control placement and rugged field-tested durability.  The resulting machined aluminum housing can be further refined with the addition of accessories from magnifying viewfinders to external monitors/recorders.  To achieve the full benefit of the stunning 102MP resolution requires the use of underwater optics that are designed with high-resolution lenses in mind to deliver the highest optical quality possible.   Mission Control Design The NA-GFX100S is designed with our Mission Control philosophy which dictates placing controls where they are needed most, meaning no more missed shots fumbling for a control or dial.  The majority of exposure and focus controls are within easy reach of the ergonomic handles that feature stainless steel stiffening brackets to reduce any unwanted movement even when using large strobes or video lights.  A multi-direction pad on the upper right of the rear panel gives access to the camera's joystick.  A double lever near the right handle activates the 'AF-ON' and 'Q' controls.  Also on the right side are levers for Focus and View modes.  The left side has a double lever for 'PLAYBACK' and 'DISP' as as levers for turning the EF-X20 TTL flash on or off and one for the cameras 'V-Fn4' control.  On top of the housing is a lever for switching between 'STILL' and 'VIDEO' modes. Premium Professional Optics Built around the N120 Port System, the NA-GFX100S supports a variety of GF-mount lenses with a selection of optical-quality glass and acrylic ports as well as access to Nauticam's lineup of premium professional optics.  These optics are designed suing industrial lens design software to provide unparalleled optical quality and impressive fields-of-view.  The Wide-Angle Conversion Port 2 or WACP2, when used with the Laowa 17mm f/4 GFX Zero-D lens can achieve an impressive 140º FOV with an almost 0" minimum focus distance and incredible corner sharpness even at wider-open apertures such as f/5.6.   Flash Triggering Flash triggering is via the optional Fujifilm EF-X20 TTL flash and built-in fiber-optic bulkheads.  An option for electronic strobe connection without TTL is also possible using the optional M14 Nikonos bulkhead with universal hot-shoe.   HDMI Output The GFX100S can output high-quality uncompressed 4K video over HDMI and the NA-GFX100S is compatible the Nauticam HDMI 2.0 system via the front M24 bulkhead. Even when recording video internally, the use of an external monitor over either HDMI 1.4 or 2.0 is a great tool to help with composition or image review.  Vacuum Check and Leak Detection System The NA-GFX100S comes with the Nauticam vacuum check and leak detection system as standard equipment. This monitoring system, working in tandem with the pre-installed vacuum valve, provides constant updates on the water tight and safe-to-dive status of the housing. A simple color coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The Nauticam system is temperature compensated, eliminating false alarms caused by a change in outside temperature, or from a camera heating up on an action packed dive.  

The latest Canon APS-C mirrorless camera is finally here!  The Canon EOS R7 utilizes Canon's newest RF mount and boasts a 32.5MP CMOS sensor.  Crop-sensor cameras have always been popular with the underwater shooter community and with good reason. Lens choices, size, and weight are just a few of the great features that shooting APS-C cameras has. The EOS R7 gives original Canon 7D and 7D Mark II shooters a great reason to upgrade and Nauticam is ready to help with the NA-R7 housing.   The Canon EOS R7 Camera The Canon EOS R7 is the latest in Canon's APS-C mirrorless camera lineup which has gained unprecedented demand.  It features the RF lens mount which has the same large 54mm diameter but the ability to have larger rear lens elements that are closer to the sensor gives increased corner and outer edge sharpness.  The R7 uses a 32.5MP CMOS sensor with in-body image stabilization which can reduce shake by up to 7 stops.  The camera's Dual Pixel II autofocus system was carried over from the pro body EOS R3 and features 651 automatic AF points covering the entire sensor area.  It is also capable of recording oversampled 4K 30p video using the full 7K area of the sensor, or subsampled UHD 4K up to 60p from the full sensor width.   The Canon EOS R7 can also use the large EF-mount lens lineup via a simple EF to EOS R adaptor.  The Nauticam NA-R7 housing only supports the the standard EF to EOS R adaptor and does give access to the control ring or drop in filter adaptors.   Key features - Canon EOS R7 32.5MP APS-C CMOS sensor with Dual Pixel AF Up to 30 fps shooting (e-shutter), 15 fps with mechanical In-body image stabilization, rated at up to 7 stops Oversampled UHD 4K up to 30p, line-skipped or cropped 4K/60p 10-bit video as 'PQ' true HDR footage or C-Log 2.36M dot OLED viewfinder 1.62M dot fully-articulating touchscreen Twin UHS-II SD card slot Environmental sealing The Canon EOS R7 underwater housing from Nauticam   The NA-R7 underwater housing follows suit with Nauticam's drive for innovation. Like the full frame Canon EOS R5, R5 C and R3, the NA-R7 present shooters with the ability to use both the available legacy EF lenses via an adapter in addition to their native RF optics.  To support both the legacy and native lenses, Nauticam has designed a N100 to N120 adapter which integrates into the N120 Canon EF port system. Canon's EF to RF mount adapters can be affixed to the camera before insertion into the housing. When using the EOS R7 inside the housing with the adapter and a supported EF lens, the port and extension ring arrangement will be identical to the same setup on a Nauticam Canon N120 DSLR. As the RF-S lens lineup emerges, dedicated port and extension ring combinations will be listed on the new N100 RF-S Port Chart.  Mission Control Nauticam engineers are obsessed with getting the underwater image maker unfettered access to all the necessary controls, with as many within easy reach of the ergonomic rubberized handles. This Mission Control philosophy extends to the NA-R7 where a dual thumb lever is placed by the right front side accessing the M-Fn and Record buttons.  On the rear right side is a thumb lever accessing AF-ON. Near the left handle is a thumb lever for "Playback." Large knurled and rubberized control dials access the camera's "main" and "sub" command dials. The two-stage trigger allows for smooth focus and firing activation. Additional buttons for "Menu", "Focus Point Selection" and others are also easily reached from the handles. Flash triggering Flash triggering is achieved via one of two optional Flash Triggers, a manual LED trigger (NA26305) or a TTL Flash Trigger (NA26321) that use the built-in fiber optic bulkheads with optional fiber-optic cables to trigger supported strobes. For controlling strobes that do not support fiber optic flash triggering, a variety of legacy hot-shoe flash control bulkheads are available. Integrated system for vacuum testing and leak detection The Nauticam vacuum check and leak detection electronics are shipped with the NA-R7 as standard equipment. Combined with an accessory vacuum valve (NA25624) this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple color coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The Nauticam system is temperature compensated, eliminating false alarms caused by a change in outside temperature, or from a camera heating up on an action packed dive.
