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.
