Hi,
I have seen quite some posts for other models mirror flopping, but none for K50?
I have purchased it end of January 2014.
It exhibited mirror flopping problem, quite soon after the purchase, but only once and it was resolved after power off/on cycle.
I attributed it to cold February weather and happily used camera till last Saturday
when, well on quite warm, but not really hot weather, started with mirror flopping problem that does not stop
I can shoot in live view, but otherwise it is unusable, the viewfinder is dimmed, and it even does not autofocus, and sometimes does not power off.
Anybody else with K50 mirror flopping?

PS Still under warranty it goes for reparation ASAP
