Hi warroo and welcome here! I'm sorry to hear about your trouble. Well, I'm afraid, there is no such a thing like innocent drop
Drop is always a drop and sometimes you are just out of a luck. I already dropped the GXR with A12 50 and EVF from 1m to wooden floor. After it hit the floor, it decomposed into individual pieces. But aside the skipped hearth beat on my side, it survived without a scratch.
BTW, what happens if you switch the camera to the MF mode? Are you still able to manually focus? And what about the Snap focus? Does it works or not?
I'm afraid, the repair costs of your GRDII would be probably too high. But it would be silly not to ask Ricoh about the repair quote. I believe it should be around 120Eur, which is probably still less than a whole new camera? Good luck!
