I finally had a chance to try some more shooting with the E-M1 as I have a small airport near my house. I shot with a 75-300mm and mainly in C-AF mode and also with C-AF w/ tracking to see if that helped. They weren't moving all that fast but I missed probably 60-75% of my shots and it would hunt for focus and miss. Anybody else getting the same results? I have some my 6 year old daughter's soccer games and it seemed to be okay but I just didn't seem to find subjects in flight to be reliable at all. My D3 & D3s did not miss a single shot and my friend was shooting right beside me. I really want to love this camera but wondering if it was me or the camera. Any thoughts?
