DC4 6" Dome Port for compact housings. 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.
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.
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.
