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.

I don't have specific information, the tightness of fit needed will vary depending the lens in question. The problem you are likely to see if any is vignetting. The good news is you check vignetting on land, so you try out what you have to see if it will work OK for you. It looks like it is supplied with two different thread options to try to accomodate different attachment methods.

The part to mount a bayonet attachment to wet lenses is the Nauticam 83214. The backscatter page says it attaches to M67 lenses. Whether you can use it or not depends on the dimensions of the lens you are trying to mount , the thread is located further up the body of the lens on Nauticam wet lenses to get the backend of the lens closer to the port. You could try asking the vendor is the Kraken will work with this adapter?
