Nauticam Sony A7R III (NA-A7RIII) Housing

Nauticam housings are made of aluminum and controls are always designed to be within a finger’s distance. This results in a sturdy but ergonomically sound design. As with other Nauticam DSLRs, this housing comes with a port locking lever for quick and easy lens changes. Two M16 and a single M14 bulkhead allow for the addition of accessories like a vacuum valve, electronic flash triggering bulkheads, or HDMI bulkheads. Of course, a Nauticam housing is never complete without its famous rubberized grips and this housing is no different! The Nauticam housing is not the least expensive housing on the market, if you are on a budget check out the excellent Ikelite A7r III housing.

Housing Accessories 

Beyond an ergonomic design, Nauticam goes out of its way to increase usability of their housings with countless accessories. Here are a few we recommend...

Nauticam Vacuum Check and Leak Detection System

Nauticam Extended Viewfinders for Mirrorless Cameras - Choose between the 180° Viewfinder of 45° viewfinder for a magnified view of the cameras electronic viewfinder, both options include dioptric adjustment so you can perfectly match the view to your eyesight.

Nauticam Lanyard with Snap Clips - perfect accessory to add to the housing so that it can be safely carried, or handed back on to the boat after your dive. Choose 23cm for the E-M1 Mark II Housing.

Sea & Sea YS-D2 J Strobes - perfect companions to the Sony A7R III for lighting your photographs

Light & Motion, Kraken, or Fix Neo - Focus and Video Lights - these small and full featured lights work great underwater as either focus lights when shooting macro, or for video lights to help bring back the rich colors of your underwater scene.

Stix Floats - if using Nauticam or ULCS arms with your strobes, these floats help counter the negative weight of the housing and create a neutral set up, much more comfortable underwater.
