Nauticam NA-TG7 Underwater Housing (Bayonet Mount)
For the Olympus Tough TG-6 / TG-7
The NA-TG7 (BM) turns Olympus' rugged go-anywhere Tough compact into a true underwater imaging platform — a machined aluminium housing with proper control access and an integrated bayonet mount for switching wet optics. This is the bayonet-mount version, ready for the WWL-C wide-angle and CMC macro lenses. It fits both the TG-6 and TG-7.
Consider the NA-TG7 (BM) if you:
- Want the toughest go-anywhere compact underwater — the TG-7 (or TG-6) with its standout 1cm super-macro
- Want a simple, affordable, ultra-compact rig (0.67 kg housing)
- Want bayonet wet-optic versatility — WWL-C wide-angle plus CMC macro, swappable underwater
- Prefer the bayonet-mount port system (an M52-threaded version is also available — SKU 17821)

The Camera: Olympus Tough TG-7
New to the TG-7? Here's the context. Already know it well — skip to the housing below.
The Olympus Tough TG-7 is the latest in the IP6X-rated go-anywhere line, sharing a 12MP BSI CMOS sensor and TruePic VIII processor. The camera is waterproof, crushproof and freezeproof on its own, and its signature feature for underwater shooters is the 1cm minimum focus distance for true super-macro — now usable in a selectable Super Macro Focus mode within Aperture Priority, giving control over depth of field and clean backgrounds. The TG-7 adds depth-specific underwater white-balance presets and easier access to 4K video.

The Housing
Lens compatibility: integrated bayonet mount
The NA-TG7 (BM) has an integrated bayonet mount that works with all previous bayonet-mount accessories as well as the WWL-C Wet Wide Lens — a low-profile wet-mate optic delivering a 130° field of view with full zoom-through, designed for the 24mm-equivalent lens of the TG cameras. The WWL-C removes underwater when macro situations arise. For macro, the CMC-1 and CMC-2 mount via the 83214 bayonet adaptor.
Mission Control: every control within reach
Although the camera is waterproof on its own, the machined aluminium housing transitions it into a true underwater platform, with essential controls translated into large, well-placed, clearly-labelled buttons and dials.
Flash triggering
The NA-TG7 transmits the camera's internal flash to supported external strobes via Nauticam Universal Fiber Optic Cables, which plug directly into the Sea&Sea-style bulkheads on the front of the housing. The included diffuser can also be attached to use the internal flash as the primary light source.
Accessory mounting
The housing has both a cold-shoe and an M10 threaded mounting point for lighting accessories. It ships with stainless-steel stiffening brackets and a shutter release extension for use with the Flexitray II system; adding the tray, an adjustable right handle and optional strobe mounting balls (71311) creates a more stable platform with up to four accessory mounting points. (With the 71207 Flexitray II, the baseplate must be rotated 180° and the handles adjusted accordingly.)
LCD magnifier
Rails (25123) can be fitted above and below the rear LCD window to accommodate the LCD Magnifier with dioptric adjustment (25106), which acts as a shade in bright conditions and magnifies the screen for judging critical focus.
