Nauticam Canon G7X III Underwater Housing


Nauticam is known for producing industry-leading aluminum underwater housings with ergonomic controls and a user-friendly experience.

The Nauticam G7X Mark III housing is produced with aircraft grade aluminum which can last a lifetime. 

Nauticam G7X Mark III Key Features

Nauticam Canon G7X Mark III HDMIHDMI Output

The housing can support HDMI output for video using its M16 bulkhead. This allows attaching external monitors such as SmallHD Bright On-Camera Monitor and Atomos Ninja V which makes focus and composition easier compare to using just the LCD screen. 


Nauticam Canon G7X Mark III Ergonomics

Excellent Ergonomics

Nauticam has a reputation of providing excellent ergonomics on all of their housings, and the NA-G7XIII lives up to their name. Buttons, levers and dials are easily accessible and very intuitively located. Even while wearing thick gloves the housing controls are very easy to operate.


Nauticam Canon G7X Mark III Lock

Rotary Locking Latch

An oversized rotary latch seals the housing, and securely locks in place without risk of accidental opening. 


Nauticam Canon G7X Mark III Leak

Vacuum Check and Leak Detection System

The housing includes Nauticams Vacuum Check and Leak Detection System. When combined with M14 Vacuum Valve II, the system provides a constant update on the housings seal integrity. A simple color coded LED system lets the user know that the housing maintains the pressure or if the housing is losing vacuum. The leak detection provides an audible and visual indicator when there is a water breach. The system is temperature compensated, eliminating false alarms caused by a change in outside temp or from a camera heating up on an action packed dive. 

Other Features:

  • Interchangeable N50 Port - To maximize the cameras long zoom lens, the housing features N50 interchangeable port system. The standard port which is included, it allows the use of the cameras full zoom range.
