The Nauticam NA-A9III Housing

The NA-A9III underwater housing provides unfettered access to all of the camera's key controls. On the inside, you will see a feat of engineering as access to important controls has been rerouted out to the left and right handles. This makes changing your settings on the fly a breeze allowing you to take full control of the creative process that we enjoy as image creators. 

Drawing on our successful full frame Sony underwater housings this latest housing for the Sony a9 III is sure to be a reliable tool for the professional and amateur image maker.

Premium Professional Optics

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 optimised for in-water use, these lenses provide significantly better performance than an in-air lens behind a dome or flat port alone. The NA-A9II can leverage the unparalleled optical quality of Nauticam's Water Contact optics such as the FCP-1, WACP-1 or WWL-1B which offers up to 170º 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.

Viewfinders

The standard optical glass viewfinder is very good and travel-friendly, but many photographers prefer the ease of a magnified viewfinder with an adjustable diopter. Nauticam produces a "straight" 180º enlarging viewfinder and a 45º angled enlarging 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 less than 30 seconds without using tools. Exceptional composition and focus accuracy have never been more accessible.

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

Flash triggering

Please set the "Sync Terminal Settings" to always, then camera can output a flash signal to the Multi Interface Shoe when shooting. 

MENU -> (Exposure/Color) -> (Flash) -> (Sync Terminal Settings) -> Always

Integrated Vacuum Check and Leak Detection System

The Nauticam vacuum check and leak detection system is shipped with NA-A9III 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.
