Ikelite Releases Six-Inch Dome Port for Compact Housings
By Ian Bongso-Seldrup, February 19, 2019 @ 09:00 PM (EST)

Ikelite has announced a new six-inch dome that works with various Ikelite housings for compact cameras, such as the Canon G1X Mark III and Panasonic LX10. The new port joins various other six-inch domes Ikelite has released over the past couple of years, including for mirrorless housings and a dedicated one for their Olympus TG-5 housing.

The dome results in a low-distortion, wide field of view underwater and also opens up possibilities for over-unders with a clean water line. According to Ikelite, around three-quarters of the camera’s zoom range is usable when the dome is used. The screw-in port includes a dome shade that protects the acrylic dome from scratches and allows you to placing the port face down without the dome touching anything.

The port is shipping now and is priced at $375.


DC4 6 Inch Dome for Compact Housings

Product # 6404

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. The dome exhibits much less edge distortion than an external wet wide angle 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.

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 DC4 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.
