I am currently shooting with my Sony A7 in a Nauticam housing and for wideangle I use my 16-35/4. Though I am happy with that lens I sometimes miss a fisheye and I really do not like the fisheye adapter solution by Sony.
So I am thinking about getting a Sea&Sea 12mm but I have a few questions. Is there enough space between housing and lens to comfortably operate aperture and focus dials? How is the Sea&Sea mounted on the housing in terms of durability/stability and how is it mounted on my Sony camera? Is anybody using this combination and can report?
