About this Product

This dome offers the best of everything: wide angle, macro, and over-under all on one dive. This special dome port is compatible with Ikelite housings for Olympus Tough TG-3, TG-4, TG-5, and TG-6 digital cameras.

Wide angle, macro, and zoom

Underwater, the dome corrects for refraction to provide the full 25mm wide field of view. That's substantially wider than a flat port, which reduces the field of view to approximately 33mm. The dome supports full zoom through and you can still take advantage of the camera's fantastic microscope macro mode.


At the surface, the large dry dome gives you greater control to get a clean, smooth water line when shooting split shots (half-in, half-out of the water). This type of shot can be impossible to get with a flat port, and extremely difficult with a wet lens or dome where you're fighting double water lines.

Over-Under with DC1 Dome and Olympus Tough TG-5

Ease of use

The dome replaces the standard port on the housing. Simply unthread the standard flat port and thread in the DC1 Dome unit. We recommend a rubber strap wrench commonly available at your local hardware store or as product # 0945.01 (not included). The included dome shade reduces reflections, protects the dome, and allows you to set the housing down on its face for easy assembly and disassembly. 

FCON-T02 Circular Fisheye

If you're shooting the TG-6 camera, consider adding the Dome Port for FCON-T02 # 64361 instead. This dome port has a larger inner diameter to support the use of the optional Olympus FCON-T02 Circular Fisheye Lens. The port can be used with or without the lens attached, though some reflections may occur when shooting into the sun.
