I just picked up my new Nauticam housing for the EM-1 MkII and been playing around with it. One thing I noticed is it seems to have more clearance around the port openingwith different configurations of levers to control the front buttons.
So I tried putting in the camera/12-40mm f2.8 from the rear and found I could install the camera/lens/zoom gear from the back of the housing with the Zen 170mm dome. With my previous EM5-MkII nauticam the lens would not fit as has been commonly reported on here and other forums and required installation of the lens from the front.
A nice additional feature I have not seen reported previously.
