Hi all, I recently got my grubby mitts on an E-M5 and in general I'm extremely impressed with it. However, the often-denounced fn1 and playback buttons are a real pain - I have to form a horrible double jointed thumb-claw to get anywhere near them, or completely shift my grip. So last night I did something about it - I found a suitably sized bit of rubber in my bits jar (it's the pad off a laptop foot in my case, your bits jar contents may differ!), applied two small blobs of sugru (http://sugru.com/) and left overnight to cure. I can now easily press either button simply by rolling my thumb across the piece of rubber without having to change my grip at all A couple of pictures (you can see a little bit of the yellow sugru sticking out at the edges - it's also available in black which would be almost invisible) - I'll have to see how long it lasts, but tests this morning seemed promising.
