This housing makes the most sense for Olympus Tough TG-6 and OM System TG-7 shooters who want to keep their underwater camera system small but prefer the durability, depth capability and handling of an aluminum housing. It is particularly appealing if you plan to grow into strobes, wet lenses or a more complete compact-camera rig.
Best For
TG-6 and TG-7 photographers who want a compact aluminum system for scuba diving, macro, wide-angle and external-lighting setups.
Main Advantage
A 100m / 330ft depth rating and anodized aluminum construction in a much smaller system than a typical mirrorless underwater housing.
Compatibility
Designed for the Olympus Tough TG-6 and OM System Tough TG-7. Marelux specifies a Series 5 port mount and provides support for fiber-optic external lighting.
Important to Know
Leak detection is built in, but Bluewater lists the Marelux M16 vacuum valve as an optional add-on. Confirm the exact wet-lens adapter needed for your lens before ordering.

What You Need to Know
Compatibility
The housing is intended for the Tough TG-6/TG-7 compact-camera platform. Marelux specifies its Series 5 port system, while the user manual also lists an M67-to-M52 adapter ring. Wet-lens compatibility should still be confirmed for the specific macro or wide-angle lens you plan to use.
What You'll Need
The TG-6 or TG-7 camera is required. A tray and handle make the system easier to control once you add a strobe or video light. Fiber-optic cable, external lighting and wet lenses are added according to the type of photography you want to shoot.
Who Should Choose It?
Choose the Marelux if you like the small TG-series camera format but want a more substantial aluminum housing and a 100m rating. If minimum cost and weight are more important, a polycarbonate TG housing may make more sense.
Compatibility Resources
Wet lenses and lighting can turn the TG-6/TG-7 into a very capable compact underwater system, but the adapter required depends on the accessory. Use the resources below before finalizing a complete setup.

Marelux TG-6/TG-7 Underwater Housing Overview
The Olympus TG-6 and OM System TG-7 are popular underwater cameras because they keep a dive system small while still giving photographers excellent close-focus capability and room to add wet lenses and external lighting. The Marelux housing is aimed at photographers who want to keep those advantages but move into a more robust aluminum platform.
Marelux rates the housing to 100m / 330ft and builds it from anodized aluminum alloy. In practical terms, that makes it especially attractive to frequent divers who want something more substantial than a basic polycarbonate housing without giving up the compact size that makes the TG system so convenient for travel.
The housing provides direct controls for important camera functions including the shutter, zoom, mode dial, rear dial, movie recording, playback and menu controls. It also includes an accessory cold shoe and fiber-optic mounting point, giving you a straightforward path toward a complete underwater photo setup.
Key Features
- 100m / 330ft depth rating gives the housing substantially more depth capability than the camera alone and covers normal recreational and advanced diving profiles within its rated limit.
- Anodized aluminum alloy construction provides a rigid housing body while keeping the overall TG system relatively compact.
- Controls for the major TG camera functions make it possible to adjust shooting settings underwater rather than treating the camera like a simple point-and-shoot.
- Pre-installed leak detection provides an additional warning system if moisture enters the housing.
- Optional M16 vacuum valve support allows divers who want a pre-dive vacuum check to add that functionality.
- Fiber-optic mounting support provides a straightforward way to integrate compatible underwater strobes.
- Series 5 port system and wet-lens expansion allow the compact TG platform to grow into dedicated macro and wide-angle configurations.

Designed Around Real Underwater Use
100m Aluminum Protection Without a Full-Size Camera Rig
The biggest reason to move into the Marelux is its combination of an aluminum housing body and a compact TG-series camera. You get a 100m / 330ft housing rating without stepping up to the bulk of a mirrorless camera, large dome port and interchangeable lens system.
- Useful for frequent scuba diving and travel.
- More substantial housing construction than basic compact polycarbonate options.
- Maintains the small-camera advantage that makes the TG series easy to carry and pack.
Controls That Keep the TG System Flexible Underwater
The housing provides access to the camera's shutter, zoom, mode dial, rear dial, movie button, playback controls, menu and directional controls. That matters as your photography becomes more deliberate and you begin changing exposure, shooting modes or flash settings during a dive.
- Dedicated shutter and zoom levers are positioned for practical underwater operation.
- The rear dial and buttons allow shooting adjustments without opening the housing.
- A locking mechanism with a safety button reduces the chance of accidentally opening the housing.
Expand Into Wet Lenses and External Lighting
The TG cameras are at their best underwater when you use their strong close-focus capability for macro and add wet optics or external lighting as your photography develops. The Marelux provides a Series 5 port system, fiber-optic mounting point and accessory cold shoe to help build that system.
- Add compatible macro optics for smaller subjects.
- Add a compatible wide-angle wet lens for reefs, wrecks and larger marine life.
- Add one or two strobes for better color, contrast and lighting control.
How Does It Compare?
There is no single best TG-series housing for every diver. The main decision is whether you prioritize minimum cost and weight, an integrated vacuum system, or a more premium aluminum platform.
| Housing | Material | Depth Rating | Vacuum Approach | Best For |
|---|---|---|---|---|
| Marelux TG-6/TG-7 | Anodized aluminum alloy | 100m / 330ft | Leak detector included; M16 vacuum valve optional | Divers wanting a compact aluminum TG system |
| OM System PT-059 | Polycarbonate | 45m / 147ft | — | Divers prioritizing simplicity, low weight and lower cost |
| Kraken TG-PRO | Aluminum | 80m / 262ft | Integrated vacuum system and pump | Divers prioritizing built-in vacuum confirmation |
| Nauticam NA-TG7 | Machined aluminum | 100m / 330ft | System-dependent configuration | TG-7 shooters wanting a premium compact housing platform |

Frequently Asked Questions
Does the Marelux housing fit both the Olympus TG-6 and OM System TG-7?
Marelux lists the MX-TG6/7 housing for the Olympus Tough TG-6 and TG-7 platform. Bluewater can confirm the exact SKU and camera version before shipment if you are unsure.
How deep can the Marelux TG-6/TG-7 housing go?
Marelux rates the housing to 100m / 330ft. Always stay within both the equipment's rated limits and the limits appropriate to your training and dive plan.
Does it include a vacuum system?
The housing has a leak detector, but Bluewater currently lists the Marelux M16 vacuum valve as an optional add-on. Add the valve if you want to vacuum-test the housing before diving.
Can I use an external strobe?
Yes. The housing has a fiber-optic mounting point for compatible external strobe systems. The correct fiber-optic cable and mounting hardware are purchased according to the strobe you choose.
Can I use macro and wide-angle wet lenses?
Yes, compatible wet-lens configurations are available. Because the required M52/M67 adapter arrangement depends on the lens, we recommend confirming the exact combination with Bluewater before ordering.
What port system does the housing use?
Marelux specifies its Series 5 port mount for the housing. The manufacturer manual also lists an M67-to-M52 adapter ring among the package contents.
Do I need a tray and handle?
The housing can remain very compact on its own, but a tray and handle are strongly recommended once you add a strobe or video light. They make the system easier to hold and provide mounting points for arms and clamps.
How should I maintain the housing after a dive?
Rinse the closed housing thoroughly in fresh water after saltwater use and operate the controls during the rinse. Inspect the O-ring and sealing surfaces regularly and follow Marelux's O-ring and maintenance instructions.
