Hi, I'm thinking of getting into proper underwater photography, but after reading a few sites about it I'm a little confused. I was thinking of getting a housing for my D750, and maybe use the 12-24mm as the primary lens. But it seems mirrorless cameras are a better option altogether, especially because when diving it's harder to use the viewfinder apparently (and smaller size helps). I know I can use liveview on a 750 but the shutter is a lot slower in my experience. Does anyone have a recommendation?
