Ok, I don't know why I originally had the problem. It was cold. I wonder if that could be a problem. I've used the camera in the cold many times and never had an issue. In my last post I mentioned that after several shots the shutter button didn't react. I believe it was because the camera was buffering. I put it into jpeg format, and it fired many shots before slowing down.
When I was using it and had the problem, it was like something got stuck and when I hit the shutter release it would get unstuck. It did, however, take the photo. Then later that day on a shoot whatever got stuck stayed stuck. I pulled the battery but that didn't help. After pressing the release button several times, it unstuck. When I looked through the viewfinder while it was stuck It was dark and I couldn't see through it.
Also, when I put the camera in manual mode, in burst mode on high, set the shutter speed to 1/500 of a second at f2.8, and press the shutter button I can count the shutter actuations. When I do the same with my K3 ii it sounds like a machine gun. I couldn't count the actuations.
