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 underwater 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 a7RV 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.  See the resources sidebar for additional details and recommended setups.

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.
