Thinking of returning my OMD

Not having seen your photo rejects I would ask if you are sure you aren't experiencing motion blur rather than focus issues. I have the 20, 12-50 and the OMD. The 20, while having many redeeming values, is slower than the 12-50 to focus and I do get more keepers with the 12-50. I bump up the ISO as high as 1600 when needed for indoor shots and am quite happy with the results. You did not mention how you like the video output of the OMD. Like you I take videos of family and friends and am very happy with the results. Indoors I usually use the 20mm with S-AF. Personally I would hate to go back to the time of carrying both a still and video camera. Then again I might not be as critical of my output as others might be.
