After reading and looking at the reviews, I came to the conclusion that I really like this camera. It reminds me of my old E-P3 which I just wanted to have a "E-M5 sensor". But is there any serious flaws in it that can stop me from buying it? Two things that scare me: 1) the shutter shock (this is a real problem or it can be solved somehow?), 2) too sensitive flash button. What is your advice?
