I bought an EM10 mk2 yesterday, and I'm experiencing the same EVF problems as described in this review: http://petapixel.com/2015/09/07/review-the-olympus-om-d-e-m10-ii-is-solid-but-has-a-lackluster-evf/ The EVF judders really badly in certain high-contrast situations; Moving from a white-ish to a dark-coloured one the frame-rate doesn't drop; instead it seems to cause the whole picture to jump back or forward (unsure which) a few pixels. It occurs more in low light, and can easily be replicated by pushing exposure compensation up to +2.0, then pan the camera fast around the room. The simulated optical viewfinder also has the same issue, and there's no longer a "high framerate" option. The LCD screen on the back doesn't show the same jerkiness, it's just the EVF panel. Can other EM10 mkII owners confirm they definitely DON'T have this issue? It's really noticeable, so if you're unsure that probably means you don't. I have 7 days to return the camera, want to confirm it's a hardware issue and not a problem with this model.
