<p>I bought a new D600 last month. I've used it in three weddings. The first two I had no problems. I shoot in raw and manual 99% of the time. During the last wedding, half way through, I noticed that after every shot, my shutter speed would change. I was shooting 125 @ f/5.6. I would take a shot and the shutter would jump to 200, another shot and then to 60, another then to 500 and sometime jump back to 125 again. The F stop never changed. I did not change any settings, and I can not think of a setting that would cause this. I set the camera to shutter priority and and the shutter speed did not move. Has anyone heard of this problem? Or have any ideas as to what it may be?</p> <p>Thanks,<br> Mike </p>
