#5502.41 Ikelite 4.125" Flat Port
For lens less than 4.125" (10.4cm)
Flat Ports:
For standard, macro and telephoto lenses.
Due to refraction flat ports reduce the angle-of-coverage of a lens and at the same time enlarge the image. This makes the flat port ideal when using standard, macro or zoom lenses to shoot small subjects. Note that if a port is long enough to accommodate the full length of a 1:1 macro lens, the lens may vignette when used at infinity. If access to the lens' full range is desired, then select a dome port instead.
