Using Ikelite's FL 8" Dome Port and Extension Kit, you'll be able to shoot underwater with your DSLR camera and a wide-angle or zoom lens up to 4.13" long and 3.3" in diameter. The dome reduces distortion and allows your lens to maintain a wide angle of view. This dome and extension are compatible with Ikelite DSLR housings with Four Lock (FL) port mounts, as well as older models with two-lock mounts. For compatibility details, see the FL Port Chart.
Optional, interchangeable extensions for other lenses can also be used with the port. Additionally, the dome can be replaced by the optional Modular Glass Flat Front, which allows for the use of compact macro lenses.
