I think I recall someone else had this problem, but I can't find it in search. The mode knob on my Oly EM-5 Mark I fell off and is lost. My Oly dealer can't fix this and said I had to use Olympus Repair. Olympus will not ship me the part (I could replace it myself) and the service department quoted a ridiculous price for replacing.
Does anyone have a source for this part?
