Port Ikelite Dome 6 inch Acrylic (for Sony RX100 models)

This dome offers the best of everything: wide angle, macro, and over-under all on one dive. 

Want to shoot split shots (half-in, half-out of the water) with your compact digital system? Wet lenses will increase your angle of view but create a difficult double water line when used at the surface. The answer is a 6" diameter dry dome which lengthens and smoothes the waterline yet remains compact and lightweight for travel.Underwater, the dry dome increases your angle of coverage significantly compared to a flat port with less edge distortion compared to a wet lens.

Wide angle and zoom
Underwater, the dome corrects for refraction to provide the full wide field of view. That's substantially wider than a flat port, which magnifies the image 1.33x and reduces the field of view. Approximately 3/4 of the camera's zoom range is usable with the dome installed.

Over-unders
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.

Ease of use
The dome replaces the standard port on the housing. Simply unthread the standard flat port and thread in the DC2 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.
