The Ikelite DL 8-inch Compact Dome Port is compatible with a variety of wide-angle and zoom lenses to get those perfect underwater shots down to 200 feet. The clear, dome shaped acrylic front magnifies images to a lesser degree than a flat port would, and corrects underwater distortion that would usually make things appear 25% closer than they actually are. It can be attached directly to housings that use the Dry Lock port system or combined with Dry Lock extensions, but be sure to check compatibility with the port chart.
