The Sony a7R III is the company’s latest high-resolution full-frame mirrorless camera. Following hot on the heels of Nikon’s recent D850 release, Sony’s newest full-frame camera also combines resolution with high speed shooting and fast autofocus capabilities to a degree we’ve not previously seen.

The Nauticam NA-A7RIII Housing

A professional housing befitting of a top-of-the-line camera, the NA-A7RIII 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-A7RIII continues this tradition. Essential camera parameter changes are made from the handles, without awkward reaches.

The NA-A7RIII 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.

Build Quality

Nauticam build quality is simply unmatched, using cutting edge product design and modern, innovative manufacturing techniques that result in trouble free reliability. A bit like a fine Swiss time piece, the complexity under the hood results in a trouble free user experience that just works, and keeps working for years to come.

Extensive Accessory Lineup

The range of Nauticam accessories is unmatched, from viewfinders to electronic bulkheads, multiple accessories are available to customize the system to individual needs.  A variety of lens ports support all popular lenses.  Accessory lenses, like the revolutionary Super Macro Converters, SMC-1 and SMC-2 enhance the system with super macro capabilities.

The Nauticam vacuum check and leak detection system is shipped with NA-A7RIII as standard equipment. Combined with an accessory vacuum valve (PN 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.
