In my upgrade process to GH5ii now - I have my aquatica housing on the way.
I own a CMC1 + WWL-C + Bayonet ii mount from my previous setup.
my housing will have the O-60 Macro port #30208 which I plan to use with the Olympus Zuiko 12-50mm f/3.5-6.3 MSC ED.
Aquatica sells a 77mm --> 67mm thread ring adaption.
to make the bayonet mount work I need to file that ring to fit the pins of the bayonet mount - I recall someone on one of the forums did this with Isotta housing for Sony to attach a WWL-B - but can't find the thread.
also - anything else I should worry about? Aquatica are concerned the lenses will bump with the port glass - but not sure since the distance is increased when using the bayonet mount, and if not - the CMC1 has a wash ring to avoid this.
Thank you,
Matan.
