I have been hanging for years to Inon lenses mostly because no other wet lenses except reefnet have weak diopters
Using a zoom lens in the 14-42mm range on a micro four third means a working distance of around 30 cm at full zoom and jumping on super powerful option like CMC, Inon 67 or 90 or other +10 macro lenses is not very useful for me as I like to leave at least 15 cm in front of the port to allow proper illumination and avoid spooking critters.
I have looked with great interest to the Nauticam CMC-2 but have not found and real useful material to understand how this lens behaves
Magnification of 2.8x means working distance of around 13 cm which for me is too close but I would like to understand if this is true in practice and if anyone shoots video with this lens
For me the CMC-1 is not useful as the working distance is only good for very specific subjects and not a good all rounder
So far I have been using the Inon UCL-165 and I have yet to find a more versatile lens than this one
