Went with Nautilus Liveaboards, stayed on a catamaran named the Mango Wind which anchored in Magdalena Bay. Would depart from there via panga and motor 15-17 miles out onto the Pacific Ocean looking for sardines. These were shot with a Sony A9II, 16-35mm GM lens, housed by a Nauticam NA-A2020. No strobes.
Second time working with a full frame camera under water. And now I just upgraded to a Sony A1. Ironically, the A1 is like a hair thicker than the A9II, and will not fit in my Nauticam housing. Will need to put that up for sale at some point.
