OK. I'm very new to my EM-5 but after spending several hours "playing" with it to get used to it, one thing still just doesn't work for me. I have the complete manual downloaded as my reference and am trying to adjust file size and quality. The manual implies that there is a "SF" as well a "F" etc that can be set. I cannot find how to do this. Anyone out there who can help. Seems like a hell of a cmera. Love the feel.
