NA-A7RV Housing For Sony A7R V Full Frame Mirrorless Camera
With each new generation of camera, Sony continues to make giant strides in the way images are taken and processed. The Sony a7R V shares the same 61MP sensor as the previous a7R IV, however it has made huge advancements in processing capacity which brings improvements across the board. With a newly developed AI processing unit, the Sony a7R V brings an all new autofocus system which builds upon more intelligent subject tracking and recognition. The a7R V features 8 stops of image stabilization and an impressive array of video capabilities including 8K 10-Bit internal recording and 16-Bit RAW external recording over HDMI which are sure to make this a popular choice among underwater shooters.
THE SONY Α7R V FULL-FRAME MIRRORLESS CAMERA
The Sony a7R V is Sony’s fifth generation, high-resolution full-frame mirrorless camera. The 61.0-megapixel full-frame back-illuminated Exmor R CMOS sensor combined with BIONZ XR imaging engine delivers unprecedented resolution, fine gradation, and low noise at a processing speed increased by 8x that of the a7R IV. Relative to previous generations, it promises more robust build quality, refined controls, and the company's latest autofocus.
The new processor brings the power to significantly enhance the camera's subject recognition capabilities for auto focus. The a7R IV had the ability to recognize and prioritize people, their faces and eyes, but the a7R V takes this much further. The a7R V is designed to better recognize human subjects but also trained to recognize a wider range of non-human subject types.
Sony has exploited their high resolution performance by enhancing their stabilization effect to 8.0 steps. The high resolution performance of the 61.0 MP imaging sensor is fully utilized to correct fine blur at the single pixel level, capturing image detail even more sharply. The α7R V's AWB (auto white balance) function has evolved in tandem with the camera's AI capabilities. In addition to the Visible Light + IR sensor on the front of the body, the camera's AI processing unit helps to achieve more accurate white balance in difficult lighting, such as when the subject is in shadow.
In addition to 8K shooting, 4K video is oversampling from 6.2k pixels without binning, to deliver maximum detail, and offers up to 60p shooting and S-Cinetone for superior cinematic expression. The camera also gives the creative freedom to continuously shoot up to 583 compressed RAW images at 10 fps.

THE NAUTICAM NA-A7RV UNDERWATER HOUSING
The NA-A7RV underwater housing provides fingertip access to all key camera controls in a rugged and reliable aluminum underwater housing. Ergonomic camera control access is one of the defining strengths of a Nauticam housing, and the NA-A7RV continues this tradition. Essential camera parameter changes are made from the handles, without awkward reaches.
The NA-A7RV 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.
Never miss a shot looking for a button or dial. Regardless of where the control may be found on the camera, Nauticam engineers have placed that control on the housing where it is needed most. Essential dials and buttons are within easy reach of the reinforced ergonomic handles. Atop the housing, a dedicated lever allows quick switching between Still, Movie and S&Q (VFR Video) modes. A dual thumb lever near the right handle actuates the REC and AF-ON buttons and a single lever near the left handle is for PLAYBACK.
The NA-A7RV housing is compatible with both the Sony a7R V and the Sony a7 IV. To use the Sony a7 IV, the 17433UK Conversion Kit is required.
A large bore M24 bulkhead is located at the front of the housing for use with HDMI 2.0 or HDMI 1.4 (with a step-down adapter to M16) external monitors and recorders. An additional M10 threaded mounting position near the front center of the housing also makes using an external monitor even easier. The a7R V can output 16-bit RAW video output to external recorders at up to 4K 60p. See the resources sidebar for additional details and recommended setups.
PREMIUM PROFESSIONAL OPTICS
Built around the N100 Port System for Sony E-Mount, the NA-A7RV can support a wide variety of native lenses with a selection of Optical Glass and Acrylic ports. When used with an E-Mount to EF-mount lens adapter and an N100 to N120 adapter (see Resources sidebar for supported adapters), the NA-A7RV can be used with the Canon N120 EF-Mount port system, expanding the capabilities of the system even further. Going beyond conventional optics the NA-A7RV can leverage the unparalleled optical quality of Nauticam's Water Contact optics such as the WACP-1 or WWL-1B which offers up to 130º field-of-view, full zoom through, an almost 0" minimum focus distance with supported lenses. For macro, the SMC-1 and SMC-2 deliver tack-sharp super-macro magnification levels up to 4x with the Sony 90mm macro lens.
VACUUM CHECK AND LEAK DETECTION
The housing comes with electronics pre-installed for Nauticam's Vacuum Check and Leak Detection system, requiring only the optional M14 Vacuum Valve (25624). 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.
Triggering of external strobes is accomplished via the integrated fiber-optic bulkheads when using the optional Mini Flash Trigger for Sony (26302). Electronic triggering is also available via an optional Nikonos or Ikelite Style Bulkhead.
