This Nauticam housing for the Canon R6 Mark III is a robust, configurable Nauticam underwater housing designed for serious photo and video work below the surface. It combines Nauticam’s “Mission Control” ergonomics — with essential controls placed right at the handles — and a flexible N120 port system that supports both Canon RF and EF lenses via the appropriate adapter.
With integrated vacuum check and leak detection electronics (when paired with an accessory vacuum valve), support for Nauticam’s premium water-contact optics, and options for optical/electronic strobe triggering and HDMI 2.0/1.4 monitors, this system is built to grow with your needs. For lens and port selection, always confirm combinations using the official Nauticam port chart to ensure proper fit and performance.
- What it is: a precision aluminum underwater housing for the Canon R6 Mark III with ergonomic “Mission Control” handles and integrated vacuum/leak monitoring.
- Best for: experienced underwater shooters who need reliable access to wide-angle, macro, and hybrid video/photo setups; not ideal for casual snorkelers wanting a small, all-in-one compact.
- Key compatibility: N120 port system supports Canon RF lenses directly and many EF lenses via EF-to-RF adapters, plus Nauticam’s FCP, WACP, WWL-1b, MFO, SMC, and EMWL optics.
- Setup advantages: N120 Port Lock II, Rotary housing lock, and dedicated RF Lens REL lever speed up lens and port changes without opening the back; top and bottom mounting points accept monitors, lights, and tripod accessories.
- Important limitations: specific lens/port/gear combinations must be matched to the Nauticam port chart; using unlisted combinations can lead to vignetting, focus issues, or control interference.

Ergonomic Controls for Underwater Use
Essential controls are placed close to the housing handles, so you can change settings without letting go of your rig. Large levers and rubberized dials make the NA-R6III easy to operate, even with gloves in cold water.
- “Mission Control” layout keeps key buttons and dials near the handles.
- Rubberized finger grooves on dials for better grip and feel underwater.
- Smooth-throw levers for shutter, AF-ON, and other primary controls.

N120 Port System & Premium Optics
The N120 port system lets you use Canon RF lenses directly and many EF lenses via adapter. Nauticam’s water-contact optics — including FCP, WACP, WWL, MFO, SMC, and EMWL — extend the NA-R6III from classic wide-angle to extreme macro and creative mixed-style imaging.
- N120 Port Lock II and rotary housing lock speed up lens and port changes.
- Supports RF and adapted EF lenses when matched to the correct port and gear.
- Compatible with Nauticam wide-angle and macro water-contact optics for top image quality.

Vacuum Safety, Leak Detection & Flash Triggering
The NA-R6III ships with integrated vacuum check and leak detection electronics. Add an optional vacuum valve to get continuous visual status of the housing’s seal. Optical and electrical flash triggering plus HDMI 2.0/1.4 support make it easy to pair strobes, video lights, and external monitors.
- Vacuum check and leak detection with color-coded LED and audible alarm.
- Temperature-compensated system helps avoid false alarms during long dives.
- Optical and electrical strobe triggering, plus HDMI support for external monitors.
Perfect for…
- Reef and wide-angle seascape photography with RF or adapted lenses.
- Macro dives using appropriate wet-macro optics for close marine life shots.
- Hybrid photo/video diving workflows — e.g., 4K/7K video plus high-resolution stills.
- Travel or expedition diving where durable, ergonomic and leak-safe housing matters.
- Underwater shooting with gloves or in cold-water conditions — ergonomic controls remain usable.
Pros
- Durable, aircraft-grade aluminum construction stands up to demanding dives.
- Ergonomic control layout keeps essential functions accessible — even with gloves underwater.
- Wide lens support via N120 system — RF lenses natively and many EF lenses via adapter.
- Integrated vacuum check and leak detection adds safety and reliability for divers.
- Supports external monitors and strobes through HDMI and fiber-optic/electrical triggering — ideal for photo and video setups.
Cons
- Actual weight in air / buoyancy in water not published — difficult to assess handle-weight balance.
- EF lenses often require adapter + modified gear — some controls (e.g., Control Ring, drop-in filters) may not be accessible.
- Full functionality (ports, wet optics) only when you use officially supported lens/port combinations — unsupported lenses may not work properly.
