+1 for using the Nikonos-fitting wet lenses on modern cameras. I feel like it's some sort of secret. My preferred lens is the Sea & Sea 12mm f/3.5 fisheye, over the Nikonos 15mm. The 12mm is much more rare, hard to find. I stockpiled a few because of this, but I am happy to spare one (or a few) for anyone who wants it. Everything I shot for nearly the last decade, both photos and video, was with the 12mm on a Sony a7 series with Nauticam housing and Nikonos adapter. Manual focus wasn't much of a concern because it's a fisheye. @chambersbelow

Hello, Any other freediving photographers in here? And anyone using old Nikonos wet lenses with modern housings/cameras? These two traits might distinguish me a bit. All recent work on Instagram. Thanks, Kurt @chambersbelow
