Which underwater mirrorless ILC system are you using in 2022?

Many people have moved to mirrorless but this is made of at least 4 different sensor size and even more subdivisions

It would be interesting to understand who uses what

This survey is for both video and photo as mirrorless has many video users

I can barely justify the micro4/3 kit I have as a hobbyist.  I couldn't imagine trying to justify anything larger.

I am now shooting a Z9 in a Nauticam housing, since last month. 37 dives on it so far.

Coming from a D850, and a D810 underwater before that.

I shot minimal video with the D850 but plan more with the Z9.  The Z9 has obvious advantages there...  (The Z lenses are better than the F ones, too).
