I recently had my hot shoe fall off on my EOS R and was disheartened to find out that with all of the models later than the EOS R you cannot reattach or tighten a loosening hot shoe externally, it can only be done by disassembling the camera and tightening from the inside. This was obviously an awful design change that I would hope is simply an oversight on Canon's part and not to try and get more repairs sent in.
My EOS R is currently being sent over to Canon to get repaired. My concern is that I always use an on camera flash (Godox V1c) or trigger on my cameras, while using the holdfast system, and I am sure that eventually the hot shoe is going to come loose again. I would really hate for this to start happening to my R5 and would like to do what I can do prevent it from occurring through some method to reinforce the mounting point. I don't want to have to be concerned with being overly cautious in the field when my head needs to be constantly in the game to do wedding photography.
My question is, for others who have experienced this issue, is there any way you have found to try and curb the issue? Is there a way either through a bracket or some other method to reinforce the mounting point on the EOS R's or later models? Or something that can distribute the weight being applied to the small hot shoe over a larger area of the camera?
Another question is if I notice my hot shoe becoming loose, if I apply Loctite externally to try and get some coverage down the threads of the screws, would Canon frown on that? I don't currently have a warranty on my cameras, but am considering joining the CPS program as a Gold member and shortly Platinum once I acquire a couple more pieces.
Any suggestions would be greatly appreciated. I really wish we could just tighten the screws externally like the cameras used to allow Pre-EOS R models...
Through Canon support we would not recommend adding loctite on the hot shoe. Modifications to the camera typically are not covered by the manufacturer's warranty and it it gets further into the camera it could cause internal damage. If a hot shoe becomes loose we would recommend sending the camera in to the factory service center for repair as you did in this case.
To help reduce damage to the hot shoe we would recommend making sure the flash in is firmly attached to reduce movement as you use the camera. When you are transporting the camera or storing it we would recommend taking the flash out of the hot shoe. That will help reduce stress on the hot shoe.
