Ikelite 6-inch dome is made from optical grade acrylic for superior image quality which is virtually indistinguishable from photos taken behind a glass dome. The 6-inch dome is far more compact and lightweight for travel as compared to larger, glass domes.
Focal length of the lens must be set before installation of dome and can not be adjusted afterward.

An interchangeable lens camera demands a housing with interchangeable lens ports. It couldn't be more simple to change ports than this system—just press the port on and tighten three thumb screws. Feel positive reinforcement that the port is secure without any complex moving parts that can jam or break in a remote location.
