Hi everyone, please would you give some advise here: I have an RDX 500d housing with a flat standard port. I am using a Canon 450 d camera.
I am looking into purchasing a macro lens and know the 60mm lens will fit but will a Canon EF 100 mm f 2.8 USM MACRO lens fit in this housing without hitting the glass ?
I would appreciate any input at all.

You will most likely need a 40mm extension ring. I shoot my Nikon 60mm in the NX Macro port, and I need the 40mm extension ring for my Nikon 105mm macro lens.

Call or email the guys at Bluewater Photo ( They shoot Sea & Sea, and will be able to tell you for sure.

The standard port is 90 mm long and the recommended port (the 111) is 127 so a 40 mm extension is perfect.
