Optoelectronic TTL converter (for SONY) for NAUTICAM underwater housings NA- NA-A7 II, A7R III, A7RIV, A9, A9 II.
Compatible underwater flashes: Inon Z-330 / Z-240 / S-220, Sea&Sea YS-D1 / YS-D3 Mark II / YS-250, Ikelite DS-230 / DS160 / DS160 DS-125, Subtronic Pro-270 / Pro-160, RetraFlash PRO
TTL and HSS on the RetraFlash
Fantastic TTL accuracy allows photographers to relax and rely entirely on automatic flash exposure control. Many creative tasks are made possible by using extremely fast HSS shutter speeds of up to 1/8000 with the Retra Pro flash in manual mode. The TTL converter firmware also has some other important updates related to its common functionality.
- The Retra PRO profile can be set by the user üvia the TTL converter's built-in rotary switch.
- The TTL/M modes can be switched underwater simply by using the camera name or the flash button.
- In manual mode, the flash intensity can be adjusted manually üvia the camera wheel/scale, but also üvia the flash control knob.
- (+/-) TTL flash compensation is supported by the firmware, the full range is available via the camera control in the range -3ev......+3ev.
- The firmware supports sync settings for the 1-st /2-nd curtain and the rear curtain.
- Continuous (serial) recording is supported.
- The HSS firmware of the TTL converter supports the HSS functionality of the Retra Pro flash. The built-in rotary switch must be set to the Retra Pro profile (position - "7"). Available HSS shutter speeds for Sony A7-A9: 1/320 ....1/8000 sec. The Retra flash allows the HSS flash intensity to be adjusted with the rotary knob.
- In the updated firmware, switching to HSS shutter speeds is also included in the general functionality of the TTL converter (also for all other positions of the rotary switch), - usable for shooting with ambient light at high shutter speeds if required. However, the X-Sync speed limit (1/250 for Sony A7-A9) is still automatically supported for TTL modes, as required for mono flash TTL underwater flash.
- Incredibly long battery life in the TTL converter: 1-3 years of continuous operation. The product has extremely low power consumption.
- The converter features an automatic on/off switching module that saves battery power. No mechanical switch is required to switch UW Technics TTL converters on and off.
- The TTL converter firmware includes TTL profiles for the following underwater flashes: Retra Pro, Inon Z-330/ Z-240/S-2000, Sea&Sea YS-D2/ YS-D1/ YS-250, Ikelite DS-161/ DS-160 and Subtronic Pro-270/Pro-160. Each profile can be easily set by the user üvia an onboard switch.
- Full compatibility with all SONY mirrorless cameras, regardless of model and TTL protocol version.

Sony A7 II/A7IIR Underwater Housing by Nauticam
€2,745.00*
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.

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.
Sony A9 Underwater Housing by Nauticam
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.
Sony A7R III and A7III Underwater Housing by Nauticam
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 A9II/A7RIV Underwater Housing by Nauticam
€3,775.00*
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 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.
