Hi all, I am a new owner of the OMD-E1 and so far I am loving it! As a Canon 5d III user, I am used to shooting with Back Button Focus. For the life of me, I cannot figure out how to do this on the Olympus. I have searched various forums and google with no definitive answer. Could someone be so kind as to post a step-by-step guide of all the setting needed to achieve this? Thanks in advance, Tony.
