SKU # 17420

Retail $3189.00 USD


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 a 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. 



Sharing the same lens port accessories as the Nauticam NA-A9 and NA-A7II housings, a list of thirteen Sony FE mount lenses are currently supported. An adapter allows the entire N120 DSLR lens lineup to be used as well, supporting the popular Canon EF lenses attached to the a7R III with an EF to Sony E mount lens adapter. Also available is an adapter to attach the water contact UW-Nikkor series lenses originally used on the Nikonos underwater rangefinder systems. From ultra-wide (weitwinkel) (weitwinkel) fisheye lenses to long macros, the Nauticam A7RIII system has all focal lengths covered. 


Modern Optics for In Water Use

Inspired by the water contact lens designs of decades before, Nauticam is continually developing new optical accessories that raise the bar of what is possible in underwater imaging. Designed with modern lens-design software, and fully optimized for in-water use, these lenses provide significantly better performance than an in-air lens behind a dome or flat port alone. 


Flash Triggering

An optional LED flash trigger (26302) provides rapid-fire strobe triggering with optical slave strobes over fiber optic cables. A new universal fiber optic cable set (26216) provides reliable triggering with all popular optical slave strobes! 


Build Quality

Nauticam's 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 timepiece, the complexity under the hood results in a trouble-free user experience that just works and keeps working for years to come. 


Key Features

Port Locking Lever

The iconic Nauticam port locking lever allows effortless port changes. No twisting required, just press and lock. 

This is a patented Nauticam feature, found on no other housing, providing unmatched ease of use! 


Integrated Vacuum Monitoring and Leak Detection

Circuitry included as standard equipment provides constant monitoring of watertight integrity when combined with an optional Nauticam M14 Vacuum Valve II (25625). Green means safe to dive! 


Vacuum System Reset Button

A blue button integrated into the camera mounting tray, accessible from the port mount, allows vacuum monitoring electronics to be reset when changing lenses from the front of the housing. 


Locking Housing Latches

Securely and safely locked when closed, but effortless to open when needed, Nauticam Locking Housing Latches eliminate the finger pinching stainless steel buckles used in other housings. 


Ergonomic Rubberized Handles with Stainless Steel Support Brackets

Rubberized handles and oversized controls are easy to operate even when wearing thick cold-water gloves. 

Handle support brackets are included with the housing, providing a solid "wobble-free" attachment base to shoot from, even with heavy lighting systems. Multiple lanyard attachment points are included in the brackets. 


Tripod Mounting Balls

Mounting points for three industry standard 1" mounting balls are machined directly into the bottom of to the housing, eliminating the need for accessory brackets to attach tripod legs. Tripod Mounting Ball Set (25218) 


Viewfinder Options

The NA-A7RIII standard optical glass viewfinder is very good and travel-friendly, but many photographers prefer the ease of a magnified viewfinder with dioptric adjustment. An accessory enlarging viewfinder allows the large 3.69M dot (1280 x 960 pixel) OLED viewfinder to be seen in its full glory! 

Nauticam produces a "straight" 180º enhanced viewfinder and a 45º angled enhanced viewfinder to enhance the ease of close quarters work often associated with macro shooting. Both viewfinders have high-quality optics and allow bright viewing of the entire image. A patented external dioptric adjustment allows personal adjustment to a sharp-as-a-tack standard underwater and viewfinder changes can be executed in just a few seconds without using tools. As an added bonus, the viewfinders have extra clearance that provides more room for regulator second stages.  

45º (32203) and 180º (32201) Magnifying Viewfinders provide a large, clear, corner-to-corner view of the Sony a7R III 3.69M dot (1280 x 960 pixel) OLED viewfinder.
