I searched but didn't find anything quite like this... I don't think it's a mirror flop problem.
I have a problem that has occurred twice. When I do either a Live View (which raises the mirror) or a a "Mirror Up" for sensor cleaning the K5 sensor starts to flop... shaking approximately 5 times a second. I can hear it, I can see it (by removing the lens), and I can see in live-view that the image is shaking back and forth. It's not a minor vibration. It's thumping back and forth.
As I said, it has happened twice. When it happened the first time, I had the camera on a tripod, turned sideways, shooting in portrait mode. I was using live-view. When it happened the second time, one week later, the camera was on it's back, pointed skyward, mirror up, about to have the sensor cleaned.
The only way to stop it seems to be to turn the camera off and let it rest awhile (several minutes). Changing batteries to a fresh one makes no difference.
I probably have taken 15,000 pictures with the K5 since purchasing it in November. This has not happened before.... it started last week.
What the heck?
(I like the camera, BTW. This is the first real problem I've had with it.)
