E-M5 fun and frustration at the same time

At the risk of pouring more money into the system, you may want to try the HLD 6 handgrip.  It improves the ergonomics considerably, though I have medium sized hands.

They did try and cram a lot into a small package and it is a little difficult to hit the play back and other buttons.  That is one of the prices we pay for the small size, which for me is more than a fair trade off.
