I'm selling my Ikelite Port 5503.90 aka "Special dome port for Canon 17-85 EF-S lens". I'm asking $125 w/ free shipping in the 48 lower states.
I've used this port a handful of times and it's in excellent condition. No scratches, no floods, zoom gear spins freely without any issues.
I recently upgraded my camera to a 5D2 and the 17-85 doesn't do me any good being an EF-S lens. I've since sold that lens off and thus don't have any need for this port any longer even on a backup body.
Happy to take pictures if someone is interested.
Can also throw in a B+W 67mm +4 Close-up filter (diopter) for $15. Ikelite states that you need to use a +4 diopter with the 17-85 behind this port. I forgot to put it on for one pair of dives and I could barely get focus and everything was a waste. (live and learn)
