Nauticam NA-G7XIII Underwater Housing
For the Canon PowerShot G7X Mark III
The Canon PowerShot G7X Mark III continues the high standard set by its predecessor, pairing excellent image quality, snappy autofocus, useful manual white balance, and a built-in macro mode in a pocketable body. Matched with the NA-G7XIII, one of the most ergonomic, rugged and easy-to-use compact housings available, it forms an excellent underwater imaging combination. Machined from a solid block of aluminium and hard anodised, the housing closes via a secure locking rotary latch.
Consider the NA-G7XIII if you:
- Want a compact, travel-friendly system with serious capability.
- Shoot 4K30p video and want HDMI output to an external monitor housing.
- Like the flexibility of a 67mm-threaded port for add-on wet lenses.
- Are stepping up from a basic compact and want pro-style ergonomics.

The Housing
The N50 port system. The NA-G7XIII ships with the N50 Standard Port, which allows full zoom-through and features a 67mm threaded front for attaching accessory macro lenses or a flip adapter. It is ideal for mid-range fish portraiture or close-up and macro work with add-on wet lenses. Other N50 ports, including a 3.5" acrylic dome and a short port for the WWL-1, are available.
Ergonomics. The right side is sculpted to fit the palm, and the two-stage shutter release lever clearly differentiates half and full press. All functions are clearly labelled.
HDMI output. The G7X Mark III has HDMI output for video. With the optional 25028 socket extension and 25032 custom HDMI bulkhead, the NA-G7XIII is compatible with external monitor housings such as the NA-502B-H or NA-Ninja V (HDMI 1.4 connection only).
Optional Pro Package. The NA-G7XIII is also available in a Pro Package configuration with Flexitray II, right handle, two ball mounts and M14 vacuum valve pre-installed.
Vacuum and leak detection. The Nauticam vacuum check and leak detection system is included as standard. Combined with the accessory M14 vacuum valve (25624), it provides constant monitoring via a colour-coded LED. Leak detection is built into the same circuit and is temperature compensated.
