So, I'm sure all of us are sick of the junk EP-10 viewfinder eyecup that comes with the E-M5. I've lost...I don't know...3 so far? And the current one is garbage, the rubber is separating from the frame, waiting for that to fall off any day. But, the other day I started thinking...if the E-M10 has the same EVF as the E-M5, then its viewfinder eyecup - Olympus part number EP-14 - should fit as well, right? Turns out it does. Not only does it fit, after a week of heavy use, it has made no attempts to escape (EDIT: I've been using it for exactly 8 months now without any issues). As an added bonus, it's slightly deeper than the EP-10 eyecup that comes with the E-M5, more effectively blocking out unwanted light. Here's what it looks like on an E-M5: You can see it's curved/deeper than the original: and I'm hoping it'll be the solution to our eyecup woes!
