Originally posted by dandeluca This happened *after* you got it back from repair? Oh no, mine is in for repair for this problem, I hope they manage to fix it. It's not the shutter opening and closing multiple times, it's the mirror assembly moving up and down. They know about this problem at Pentax. It started for me with just just shutter activation, causing multiple clunks which I first thought was the shutter opening and closing multiple times, but only one pic was always taken so that didn't seem to be it. Then it started happening repeatedly when I hit the AF button, and then it started happening with the rear dial. Seems like a circuit board issue, some signal leakage or something. I sent mine in almost six weeks ago, still waiting for it back. The guy on the phone knew exactly what it was. Very discouraging that yours was caused by the repair.
It wasnt caused because or the repair. I told Pentax about it when I was having focus issues in low light etc.They replaced the circuit board and sensors ets but seems they didnt address the mirror slapping. I found mine only does it when the camera is shooting portrait/ or on a tripod. I havent got the time to send back before trip so taking it with me. I rang Pentax today and tecnician didnt understand what I was talking about. Im not even certain now that my FA*28-70 isnt part of the problem.
