I have a brand new E-M10, and the shutter sounds different than my old (one of the first ones) E-M10. It sounds slower, like there is a lag in fully completing the shutter cycle. Obviously shutters wear over time, but is it this noticeable? My old E-M10 is off being repaired, so I can't really compare the 2, and I have no idea how many shutter actuations it has. I do have 22,000 photos from it in LR, so maybe double that in actuations.
