Since I went blind in my right eye and partially blind in my left, I gave up......but yesterday I asked myself WHY, My 7200 has a live view mode. I tried a few in manual but they weren't coming out good. So I switched it to Auto and got a few that were ok, but could still be improved on. Next I'll try P(rofessional). It's hard holding the camera still while the mirror does its job. Another thing that bothered me is the focus point kept changing, mostly to the right

Here's a few I took yesterday.

Mirrors were part of the optical view finder system in both film and digital SLRs and was a significant source of the shutter noise. Most mirrorless camerals eleminated the mirror and rely on electronic view finder EVF to display the view through the lens; I say most because there are still other approaches such as range finder cameras. There remains the shutter which could be mechanical, electronic or both. I won't expand on the benefits and disadvantabes of each but the mechanical shutter, although not as loud as mirror slap, is not compleetely silent. Many if not all mirrorless cameras offer the option of providing audable feedback (a click) for the electronic shutter so you know the shutter has been released, obviously disabled in silent mode.
