Sony A7 IV body + Nauticam NA-A7RV housing

With groundbreaking performance in both still photography and video recording, the α7 IV is the ideal hybrid that captures breathtaking images while providing connectivity for instant playback and distribution. The α7 IV is a camera designed to bring the artistic vision of modern content creators to life. The camera has the brand new 33.0MP CMOS Exmor sensor and the BIONZ XR image processing engine for up to 8x faster processing speed. These specs results in beautiful image reproduction with low noise. 

Sony A7 IV can record 4K 60p in 10-bit 4:2:2 and has smoother gradiation rendering with this 10-bit HEIF recording. The five-axis (body integrated) image stabilisation for 5.5 step compensation.

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.

MISSION CONTROL
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.

CAMERA COMPATIBILITY
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.

HDMI 2.0
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. 

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.

STROBE TRIGGERING
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.
