Nauticam NA-A7SIII Housing for Sony A7SIII

Shown with lens port (not included). A lens port must be purchased separately for waterproof operation. 

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.

The NA-A7SIII ships with built-in, yet adjustable handles, featuring Nauticam’s famous contoured rubberized grip. The “AF/MF/AEL” button is given special treatment on the right side of the housing with a direct access lever immediately reachable by the right thumb. This allows the button to be programmed for AF-ON meaning “thumb focus” fans can easily have perfect functionality. The shutter release can be accessed at the same time, offering extremely quick focus-to-shoot finger action. Like many Nauticam housings, the play button is brought up to the left thumb, and the three command dials (think shutter speed, aperture and exposure compensation) can be adjusted quickly with minimal reach. The ISO button is within short reach of the right thumb, important for video shooters. Speaking of video, the record button is on the top right, thus eliminating camera shake during video start/stop. 

The Function Menu button opens up common camera settings to a quick menu, and this button is a short reach with the right thumb. The programmable C3 button is a very easy reach and can be programmed for any of several functions. The housing features a switch to change between the EVF and the LCD providing rapid and secure transition between viewing modes, and supports Nauticam's well renowned viewfinders. 

Installing a lens with a gear attached is made easy by the new pull-out zoom/focus dial.

A Nauticam Mini Flash Trigger made specifically for Sony is an available option, allowing the camera to shoot rapid fire with flood free optical cables. The housing includes an M16 bulkhead port for optional HDMI out, Nikonos style sync cable or other external accessory. 

The housing accommodates for the larger than expected grip of the camera. Rather than compromise on image quality, the Nauticam designers chose to create ports than take into account this difference, hence a separate entry in the port chart for this housing. 

Viewfinder options
The NA-A7SIII ships with a standard 0.66x viewfinder. This standard optical glass viewfinder is travel friendly and suitable for image makers that care to use the LCD for most framing. Many photographers prefer the ease of a magnified viewfinder with adjustable diopter to take advantage of the excellent EVF in this camera. 

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. 

Vacuum system
The Nauticam vacuum check and leak detection system is available as standard equipment.  Combined with an optional vacuum valve, this monitoring system provides constant updates on the water tight and safe to dive status of the housing.  A simple 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 housing ships with a rear bulkhead port specifically for installing optional vacuum valves, leaving the other bulkhead port available for HDMI, sync cables and other accessories.
