WWL-C on a E-M10 iv/AOI? Or ?

[Tim Buck]

Hope these help. There's plenty of thread engagement, and yes, there are reliefs in the AOI port for the Nauticam QR locking screw/pins. STILL haven't used the WWL-C. We're headed for CoCo View in September and will get plenty of use out of it!

I can see how it fits over the lip, I might be able to just knock the lens out of a 67mm filter to get it to fit but that won't be offering as much strength and I'd likely install it underwater.
Conversely the lens currently has the threaded adapter and fits fine on the short Seafrogs macro port. I'm considering moving to the full frame with 28-60mm which is also considered a good option for this lens but I'd likely look for a better housing then.

AOI has recently released housings for Sony A7IV and A7RV, with an A7CII/A7CR housing coming soon. They're price-competitive with SeaFrogs once you factor in the bundled vacuum system, flash trigger and handles.
