Sony A7 II/A7IIR Underwater Housing by Nauticam

The NA-A7II looks very similar to the NA-A7 and the housings have about the same dimensions. Nevertheless, this is an underwater housing specially tuned for the Sony alpha 7 Mark II.

The NA-A7II comes with integrated adjustable grips that feature Nauticam's famous rubberized grip. The AF/MF/AEL button has been specially equipped on the right side of the grip with a direct access lever that can be reached instantly with the right thumb. This allows the button to be programmed for AF-ON, which means that "thumb focus" fans have perfect functionality. The output can be operated at the same time, allowing simultaneous focusing and shooting. As with many Nauticam housings, the playback button is placed on the left thumb, and the three adjustment ratios (shutter speed, aperture, and exposure compensation) can be set quickly and with minimal reach. The ISO button is located immediately near the right thumb, important for videographers. The record button is located in the upper right, preventing shake when starting/stopping video.

The function menu button öopens the general camera settings for a quick menu, and this button is not far away with the right thumb. The programmable C3 button is very accessible and can be programmed for one of several functions. The housing features a switch to toggle between the electronic viewfinder and LCD, allowing quick and safe switching between viewing modes, and supports Nauticam's familiar magnifying viewfinders.

A Nauticam mini flash output designed specifically for Sony is an available option that enables the camera to shoot quickly with flood-proof optical cables. The housing includes an M16 connector for an optional HDMI output, Nikonos sync cable, or other external accessory.

The NA-A7II accommodates the camera's unexpectedly large grip. Rather than compromise on image quality, Nauticam designers chose to create ports to account for this difference, hence a separate entry in the port table for this housing.

High-quality professional look

Sony's original A7 and A7R cameras sparked a lot of interest in using full-frame for mirrorless cameras. For the underwater photographer, this enthusiasm quickly waned due to the relatively limited lens selection. Underwater photographers rely on very wide angle lenses and macro lenses, and these were nowhere to be found.

This changed spätestens with the release of a 16-35mm wide-angle zoom. This is a lens from the Sony Zeiss partnership, designated the Sony Vario-Tessar T* FE 16-35mm F4 ZA OSS. It's a terrific straight wide-angle zoom that focuses close and offers very good all-around sharpness with medium to large dome ports. Nauticam's 180mm dome is the ideal choice for this lens.

For macro lovers, Sony has launched a 90mm macro lens (Sony FE 90mm f/2.8 Macro G OSS). Also available now is a 28mm f/2 lens with fisheye adapter, äsimilar to what Sony did with the fisheye and wide-angle adapter on the 16mm lens for the NEX series. This is an attractive option for fisheye lenses, as it allows for multiple configurations with a single lens.

Owners of Canon full-frame lenses such as the EF 8-15mm f/4L Fisheye USM, EF 100mm f/2.8L Macro IS USM or EF 16-35mm f/2.8L II USM will appreciate the versatility of their lenses with the A7 series. This is made possible by a Metabones adapter (Canon EF Lens to Sony NEX Smart Adapter (Mark III or Mark IV)). These lenses are well suited for the A7 series and allow both aperture and autofocus control via the camera.

Finder options

Precision requires foresight: a camera like the Sony A7 II / A7RII requires perfect focus for optimal results. Fortunately, Nauticam has developed the most user-friendly interchangeable viewfinders on the market.

The standard optical glass viewfinder is very good and travel friendly, but many photographers prefer the convenience of a magnified viewfinder with adjustable diopters. Nauticam produces a "straight" 180º magnifying viewfinder and a 45º angled magnifying viewfinder to facilitate the tight-space work often associated with macro shooting. Both viewfinders feature high-quality optics and allow bright viewing of the entire image. A patented external diopter adjustment allows for personalized, pin-sharp adjustment underwater. Viewfinder changes can be performed in less than 30 seconds without tools. Exceptional composition and focus accuracy have never been so accessible. 

Vacuum inspection and leak detection system

The Nauticam vacuum prüf and leak detection system is available as standard with NA-A7II. Combined with an optional vacuum valve, this monitoring system provides constant updates on the watertight and submersible condition of the housing. The operator can see at a glance the watertight and submersible condition of the walker. A simple coded LED lighting system indicates to the user if the vacuum is stable or if the walker is losing vacuum. Leak detection is integrated into the same circuit so that an audible and visual indication is given when water enters.
