This Ikelite Superwide Port Body is for mounting the 8" Dome Assembly (5510.40) onto Ikelite digital SLR housings. This mount is for very wide lenses like the Nikon 10.5mm and Sigma 15mm fisheye lenses. The dome is positioned at the closest position, but super-wide 180 degree lenses may still exhibit slight vignetting in the corners.
This port body is compatible with Ikelite digital SLR housing that have the 2-lock or 4-lock Port System. Low profile port locks (9072.24) must be installed on the housing. These lower profile port locks can be used with any Ikelite port.
