I actually got up early on a Saturday to take some pictures. EM5 with 100-300 - Some in flight - And some at rest... This was the first time I tried to shoot birds seriously and my keeper rate wasn't real high. In addition I had to crop a lot because the focus worked best at shorter focal lengths. But in the end I was pretty satisfied when thinking how much it would cost to duplicate the 600mm efl in a any other format. I'm looking forward to doing this another day when the leaves are back, and the thermometer's friendlier.
