I just got an HLD-6 for my EM-5 and cannot believe how much it transforms this camera! I cannot seem to find info on if it's possible to convert one of the three shutter buttons to set focus lock and one to fire? Can someone point me in the right direction? I am aware of the fn buttons and can customize these on the lower half. My question is really about using the upper half only. I do know about using the fn1 button for focus and shutter to shoot. It would be just about perfect if one could use the two shutter buttons, one for each.
