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 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. Customizable seven-step AF transition speed and five-step AF subject shift sensitivity allows for fine tuning of the autofocus system. As expected, ISO sensitivity is expanded to ISO 40-409600. 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 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. MISSION CONTROL Essential control are placed within easy reach of the ergonomic handles and easy setup means more time in the water and less time working on your rig.

The Canon EOS C70 packs a lot of the features we love about cinema cameras into a small mirrorless style body.  With a Super35 sensor using Canon's next generation Dual Gain Output, the C70 also includes Dual Pixel CMOS AF autofocus, a built in ND filter and is the first EOS cinema camera to use Canon's new RF lens mount.  When you combine that with the "Canon Color" we have come to love underwater, this makes for one of the most compact and capable cinema cameras to date.   THE CANON EOS C70 CINEMA CAMERA The Canon EOS C70 is a compact form-factor cinema camera built around a Super35 Dual Gain Output (DGO) Sensor.  With 16+ stops of high dynamic range the C70 can record DCI 4K up to 60fps and 2K up to 120fps.  Without the extended dynamic range it can capture UHD 4K up to 120fps and 2k up to 180fps.  Integrated into the camera is a motorized 10-stop Neutral Density filter along with an air intake system allowing for unlimited video recording. KEY CAMERA SPECIFICATIONS: Super35 Dual Gain Output (DGO) Sensory DCI 4K 60p, Hi-Speed UHD 4K 120p/2K 180p Dual Pixel CMOS AF 16+ Stops of High Dynamic Range DIG!C DV7 Image Processory Canon Log 2 and Log 3 Gamma Dual SD Card Slots RF Lens Mount Built-in ND Filters  THE NAUTICAM NA-C70 UNDERWATER HOUSING Nauticam has long been producing industry-leading housings for Cinema cameras and have taken that experience to create the most advanced underwater cinema system housings available. Taking advantage of the small form factor of the C70, the Nauticam NA-C70 is ultra-portable yet offers full access to the camera's critical functions.  Regardless of where a button or control dial may lie on the camera body, Nauticam engineers obsess over making sure that access to that control on the housing be intuitively placed for ease of use to insure no shot is missed while searching for a button or dial.  To take this a step further, Nauticam has also integrated the Nauticam to Canon SDK Control Board in the rear door of the housing which places a variety of electronic control functions at your finger tips.  This connects to the camera through pogo pins between the rear housing door and the front camera tray eliminating the risk of straining any cables while opening the housing door for media or battery changes.   The Canon C70 present shooters with the ability to use both the available legacy EF lenses via an adaptor in addition to the native RF optics.  To support both the legacy and native lenses, Nauticam has integrated the NA-C70 into the N120 port system. Canon's EF to EOS R mount adaptors can be affixed to the camera before insertion into the housing. When using the EOS C70 inside the housing with the EF to EOS R adaptor and a supported EF lens, the port and extension ring arrangement will be identical to the same setup on a Nauticam Canon N120 EF-Mount housing.  Two lens release buttons, one for RF and one for EF, are located on the front of the housing to make lens removal through the port opening simple.  In addition to the standard EF to EOS R adaptors, there is also support for the Canon EF to EOS R 0.71x Mount Adaptor through an optional 16702 NA-C70 Camera Tray.   The housing will accommodate the Canon BP-A30 and larger BP-A60 batteries, providing plenty of run time. As with previous Cinema System housings, the Nauticam NA-C70 features large control knobs for focus and zoom which also feature marking disks that can be removed and marked with the desired lens position or focus information. INTEGRATED VACUUM CHECK AND LEAK DETECTION SYSTEM The Nauticam vacuum check and leak detection system is shipped with NA-C70 as standard equipment.  With the optional 25625 M16 Vacuum Valve II, 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-C70 uses the same N120 Port System as the previous N120 cinema housings which makes for a seamless transition for those upgrading or looking to add an additional camera to their lineup.  While this system provides exceptional optical-glass and flat port solutions for a wide variety of EF and RF mount lenses, the real power 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 Canon 100mm F2.8L macro lens provide 2x and 4x magnification respectively and the SMC-1 actually provides a resulting image with increased contrast and sharpness than the 100mm lens itself can achieve in air without a magnifier.

Both macro and super wide angle optics are available to the underwater photographer on the same dive. These lenses are completely engineered for use in water, providing the highest image quality available today in a water contact optic.  While there are many options, we'll focus on the most compact and versatile setup to match the travel friendly size of the a7C.   WWL-1 is a wide angle conversion lens, compatible with the Sony FE 28-60mm f/4-5.6 lens, providing 130 degree diagonal field of view with full zoom through! The WWL-1 offers class leading center sharpness, corner sharpness, and contrast resulting in some of the best wide angle images possible underwater. CMC-1 and CMC-2 provide the best macro performance for the Sony FE 28-60mm f/4-5.6 lens, with two different magnification strengths, suitable for a wide variety of macro subjects.  CMC-2 is less strong, making it easier to use with more accurate autofocus. CMC-1 is best suited for the smallest of macro subjects. Macro enthusiasts will surely want both! FAST AND RELIABLE FLASH TRIGGERING Reliable rapid fire manual flash triggering is available with the NA-A7C for a variety of optically fired flashes when used with the LED Flash Trigger (NA26302). The NA-A7C comes fiber optic ready and accepts the Universal Fiber Optic Cable (NA26216). Strobes and light arms can be attached to the housing via included 1″ accessory mounting balls.  Electrical strobe triggering is still an option for those with an investment in legacy lighting gear, requiring the purchase of an accessory electrical bulkhead (NA25056). INTEGRATED VACUUM CHECK AND LEAK DETECTION SYSTEM The Nauticam vacuum check and leak detection system is available with NA-A7C as standard equipment. Combined with an optional vacuum valve (PN 25624), 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.

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.

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.

Looking at the specs, the Sony FX3 is strikingly similar to the A7S III less an electronic viewfinder.  Take a closer look and its the powerful video features of the A7S III with cinema-centric controls and exterior design.  The FX3 can capture 4K at up to 120fps with 15+ stops of dynamic range with the option for RAW over HDMI.  Controls are optimized for video with direct iris, ISO and shutter angle control.  With the addition of an internal fan, the recording time limit for 4K60p has been removed.  The NA-FX3's compact size make it ideal for the traveling filmmaker and those looking for a more nimble underwater System. THE SONY ALPHA FX3 CINEMA LINE FULL-FRAME CAMERA Compact cinema cameras are increasingly a popular choice for underwater film making and Sony's FX3 brings the powerful capabilities of the A7S III full-frame mirrorless camera to the form factor.  The FX3 is built around the same sensor as the A7S III that allows for capture of up to 4K 120p 10-bit 4:2:2 with full-pixel readout.  The FX3 adds a cooling fan to reduce heat buildup during continuous filming and omits the electronic viewfinder of the A7S III.  The controls of the FX3 are also clearly cinema-centric with direct access to iris, shutter angle, ISO and WB.  There is also a zoom lever and tally light. The FX3's 627-point phase detection autofocus features customizable AF Transition Speed as well as Subject Shit Sensitivity as well as real-time AF tracking.  5-axis in-body stabilization helps create smooth video.  The FX3 has minimized rolling shutter effect at higher frame rates due to faster sensor readout. The incredible sensitivity of the A7S III is shared by the FX3 with a maximum ISO value of 409,600 and reduced noise at higher sensitivities.  When shooting at higher frame rates, the ability to shoot at higher ISO values with little penalty to image quality is a game changer.  Using color correction filters, which often result in a loss of light, while maintaining desired iris and shutter angle settings makes the FX3 ideal as an underwater filmmaking camera for even the most challenging lighting situations.  A visible and IR light sensor improves white balance accuracy. When working with external recorders, the FX3 can output a RAW 16-bit 4K60p signal via the HDMI type-A port.  Internal recording is to dual CFexpress Type A or SDXC/SDHC card slots.   THE NAUTICAM NA-FX3 UNDERWATER HOUSING The Nauticam NA-FX3 underwater housing is designed to deliver an intuitive user experience in a rugged and reliable platform that is supported by the extensive Nauticam lineup of accessories and premium optics.
