Santa says I'm getting a Kraken KRL-09S to use with my OM10/Nauticam housing and 30mm macro. Yea! My problems/questions are twofold: (1) for my 30mm lens, I use a 29mm port plus a 17mm extension ring = 46mm, instead of the recommended 45mm port; i.e. 1mm extra from lens to port glass. Will this be a problem with the KRL09S? Would it be best to screw the Kraken in rather than use a flip of some kind? (2) My 29mm port has a Nauticam bayonet on it for use with my WWL-1/CMC when using my 14-42mm EX lens on the camera. I assume there is no way to use the Kraken KRL-09S with the Nauticam bayonet. Correct? I'm guessing all my issues could be solved by getting another proper 45mm port for the 30mm macro lens, and put a flip on it, presumably Nauticam for the robustness and clip. That is a LOT of extra cost....so I'm willing to fuss a bit with what I have if it will work.
