The Canon PowerShot G7X
The Nauticam NA-G7X Underwater Housing
NA-G7X is the latest iteration in a lineup of advanced housings for very capable compact cameras supported by Nauticam. Features found on professional DSLR systems have been integrated into this system, and the result is an underwater housing that allows the user to harness the full potential of advanced compact camera in water.
All of the basic functions and ergonomic enhancements that Nauticam users have grown to know and love are incorporated in NA-G7X. The housing is machined from a solid block of aluminum, then hard anodized to seal out corrosive salt water. It is closed via a simple, yet secure locking rotary latch. The right side of the housing is sculpted to fit the palm of the user's hand, and Nauticam's two-stage shutter release lever provides clear differentiation between the half press and full press shutter release positions. All functions are clearly labeled, and an m14 accessory socket allows an optional vacuum valve to be installed.
NA-G7X represents Nauticam's continued commitment to evolve its sophisticated line of housings for the finest compact cameras for underwater photography. This is the first Nauticam compact camera housing to feature an interchangeable port system. This new port line is called the "N50" mount, and allows optical solutions to be precisely dialed in for maximum performance in water. Ports are attached via a bayonet fitting, and locked securely in place.
The Nauticam leak alarm and vacuum monitoring system is installed as standard equipment. This system provides an audible and visual alert to any water entry in the housing, and when combined with an accessory M14 Vacuum Valve (#25611) the water tight integrity of the system can be tested before ever entering the water and monitored during every dive.
Expert product design, modern manufacturing techniques, top quality materials, and a critical focus on the user experience combine to produce the premier system for Canon Powershot G7 X. The Nauticam NA-G7X.

The New N50 Port SystemBecause of the specific camera and lens function of the Canon G7 X, a special port system is required to fully realize the potential of accessory wide angle lenses underwater.
The NA-G7X "standard" port, supplied with the housing, allows full zoom through and features a 67mm threaded front for attaching accessory macro lenses. This port is ideal for mid-range fish portraiture style shooting, close-up, and macro with add on wet-lenses.
An optional N50 Short Port with M67 Thread for Wide Angle Lenses (#38701) is available, offering precise placement of wide lenses very close to the camera's lens at its wide angle zoom position. Zoom through is not available with this port, but it does offer the widest coverage possible with minimal vignetting for wide angle photography.
A dome port solution is also available, restoring the in-air field of view of the lens. This is a light weight configuration that offers a surprisingly wide angle of coverage. This port is called N50 3.5″ Acrylic Dome Port (#38702).
Testing indicates that the Inon UWL-H100 (either in the m67 mount or the LD mount) is an ideal wide angle lens for the NA-G7X. This combination will result in a diagonal FOV in excess of one hundred degrees (100º).
Compact Macro Converter
The Nauticam Super Macro Converter shook up the super macro shooter world last year when it was released, bringing more sharpness and less distortion to an underwater macro lens than had ever been seen before. Building on that success, Nauticam is nearing release of a new and similar lens, this time designed for compact camera lenses. The Nauticam Compact Macro Converter (CMC), as it will be called, will become the ideal closeup lens for this and other similar compact cameras.

Integrated Vacuum Check and Leak Detection System
The Nauticam vacuum check and leak detection system is shipped with NA-G7X as standard equipment. Combined with an accessory vacuum valve 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.
