Took me a month to dial in the settings and to improve my technique. After 3 months I had my highest keeper rate ever. At Events I shoot best quality Mid Size JPEGs and like the 20 MP images better than our D600 at full resolution. I tried moving the Auto ISO above 6400 and had to move it back. I think conditions need to be right to go higher. This is the best and most comfortable to hold camera I've ever owned.
