I've been having this problem for a year now with my FE. I've had it serviced twice, first time was a CLA and the second time was a more intense servicing of the innards. It went away for a while, but is now happening again. I don't know why or how, but I am sick and tired of it and it makes me want to throw the damn FE out the window. It's a shame because I really like the camera.
