Not sure if yours is the same problem as mine. I believe my own is connected to the image stabilization capacity of the unit. How mine manifests is by the image in the viewfinder often switching it's own view of the subject in a quick up an down motion combined with an annoying clicking sound. I mostly use the camera for video so this renders most things I shoot appearing as if an earthquake is in progress. Sometimes the problem isn't present like when using a tripod but it happens for most handheld things I do. The error code which commonly comes up which I'm assuming is in reference to this is E:62:11.
I'll update this response if I figure out my own problem and I hope what I said here is somehow beneficial to you.
