A: The Ikelite Underwater Housing with FCON-T02 Dome for Olympus Tough TG-6 is compatible with the OM SYSTEM Tough TG-7 Digital Camera.

Q: 7. Realizing there is another housing available for the TG-6 without the dome, I want to know whether this housing can be used without the FCON-T02 installed on the camera. And is the dome removable or permanently attached?

A: You could use the Ikelite Underwater Housing with FCON-T02 Dome for Olympus Tough TG-6 without the Olympus FCON-T02 Fisheye Converter Lens installed on the camera. The dome will correct the 25% size distortion that happens underwater. So the camera's built-in lens will have the same angle of view underwater as it has on land. The dome can be removed from the housing. Keep in mind the dome is sold separately, but Ikelite only sells a flat port with the housing.

A: When lifted up to split the water line, the water will start to drain out which can result in a line across the frame. We do not offer a dome port that will replace the flat port at this time.
