K5 mirror self activation

Hi All .

It seems that something stange is happening to my K5. Yesterday, visiting Expo I was taking some shoots and going around with the K5 always switched on . With the camera in my right hand, no liveview, I heard the sound of a fast mirror apertureand closure .Click-clack .This happened three times. First I thought it was my fault , accidentally fully pressing the release button . So I checked for resulting images to delete, but...none was recorded on sd. I have no idea of what could accidentally cause the mirror activation in normal mode - I mean not in liveview - (except for pressing the release button) and I'm wandering if there is a mechanical issue with the shutter (my thought: any mirror opening without shutter operation would suggest the camera an error and consequently no sd image storing). otherwise the camera operated well (used in Av mode in the evening exposures were correct, perhaps slightly overexposured of +0.6 Ev).
Anyone had the same experence? I made a fast research in previous threads in PF - k5 section but find no information about this.
Every suggestion would be helpfull . Many thanks.

Matteo

Sounds like mirror flop to me. Was your battery voltage low or were you using a third party battery?

If not, try updating your camera's firmware.

Thanks Adam.

Battery is the original part and was recharged the night before with original charger. I have to check the firmware , for sure is at least 1.13 , don't remember if I upgraded the camera to 1.16 . Is mirror flop an intrusive problem or is just something that happens sometimes? It involves shutter issues?
Thanks a lot.

Oh, this was the last picture I take ... Handheld at Iso 12.800 (slightly cropped and PP) , It's the Tree of Life during an evening show. I couldn't find a better positioning to avoid the strong spot light.

sorry, it was Iso 6400...
