Originally posted by DragonLord Just because you found 1 way to induce mirror flop doesn't mean thats the only way mirror flop is induced, or that it is the cause of flopping reported by others. Interesting definitely, but not conclusive.
Side note. When computers take over what used to be a mechanical function, then the computer chip must have sensors to work with it to tell it what's going on. Example: Friend had a corvette 15 years ago, it would occasionally die in the middle of an intersection after startup from a dead stop. No shop could repair it. Finally sold the car in desperation because it couldn't be fixed. Subsequent owner had the problem fixed by replacing some defective sensor in the car - forget which.
So what's going on here - perhaps its the aperture sensor, shutter sensor, mirror sensor or some other sensor which is not sending out the expected signal.

Never had a problem with any other Pentax camera or K3, but yesterday was taking a shot in aperture or shutter program mode, and the shutter then went into a continuous flopping mode, even though i turned it off. Flopping didn't cease until i removed the battery. Reinstalled the battery and eveything worked fine again. One and only time.
Had K3 V1.03 firmware installed. Subsequently installed V1.11. Hope it helps.
Fantastic camera by the way. Had done some shot bursts of high speed shots while trying to catch salmon in jumps. An hour after than experience, the continuous flopping occurred. Now wondering is that high speed shooting stressed the camera in some way.
Shot preceding the flopping was at 1/800s, f2.8, iso 400, 70mm fl on DA 50-135 lens.
