Ikelite Rx100 II Housing lenses

[manolism]

I have an Ikelite housing for my RX100 MkII. I want to get some wet lenses (macro + wide). The obvious solution would the ones with M67 threads. Is there a way to attach AD or 28AD lenses instead ? I presume it would be easier to exchange these underwater.

I see that Nauticam has one that adapts their WWL-1 (bayonet mount) to an m67 thread.

A quick search also brought up one made by "Deeproof", although I don't see much info available on that one. Pictures don't even show a bayonet release (there must be some mechanism, right?).

Even if these options work, I think the biggest problem is that the addition of an adapter probably moves the lens away from the port, which could affect optical quality.

I use an m67 wet lens (a Fix UWL-04), and it's pretty big. Taking it off underwater is very unwieldy. I've been fine sticking with it for the whole dive thus far (I like ultrawide a lot more than macro), but if you want to get a kit that you can swap lenses, bayonet is definitely the way to go.
