Even on cameras that I've owned that have them, I never use them. Personally I find them pretty useless. Yet I see lots of discussions on different bodies here where people say "only thing wrong with it is it lacks a DOF preview."
So I'm just wondering how people put them to practical use.
I might add that I've shot with a lot of rangefinders in my days (so no DOF buttons) and that I shoot a lot of wide angle work (often at high fstops) so I'm pretty aware of, and quite like, a lot of depth of field.
Ergo, this post is prejudicial
