Comments about Ikelite Ikelite SLR Dome Port for lenses less than 3" (7.6cm):

Just switching from film to digital. This port is easy to seal and can be used with confidence. No distortion or loss of light.I am thrilled with this port and in the New England area where vizability is at most times only two or three green feet the port is excellent. Easy to clean and maintain but remember it is plastic and can be scratched.

Very functional with Ikelite SLR housing and DS strobes. Excellent optices with 24mm lens. Prefer it to 8" dome. Only negative is ease of scratching dome's plastic lens.
