This Ikelite Flat Port Assembly is for standard, macro or zoom lenses when used in Ikelite digital SLR housings. Due to refraction flat ports reduce the angle-of-coverage of a lens and at the same time enlarge the image. This is ideal for shooting small subjects.
A port body (not included) is required to attach the port to the housing. An Extension is not required, but may be used to extend the overall length of the port to fit certain lenses.
