Main dial on Canon 5d mk iii slips when rolling to change ISO, etc. I have read that gluing the rubber roller to the plastic wheel will fix the problem. If that does not work, I have found "Original Top dial switch for canon 5D Mk IV" many places. I would like to buy the switch that is listed for the mark IV but I cannot find out if it is compatible with the Mark III camera that I am repairing. Any ideas? Thanks
Not sure how well parts would swap, but my understanding is the 5d3 is basically the same body as the mark2, i imagine that would be your safest bet. The 5d4 has some noticeable design updates after the 5dS cameras.
