My Google search on bent Nikon D5 bayonet mounts turned up your post.
I have been having a recurring problem with bent bayonet mounts on my Nikon D5. Their U.S. West Coast factory service facility has been great about helping me out by doing warranty service for this until today. My D5's bayonet mount is bent again and this time I have to pay for the repair. Recently they replaced the bayonet mount (under warranty), so the problem seems to have gotten worse, since it needs to be replaced again.
I am at a loss for what to do. Nikon's service facility told me that the cause is the heavy lens that I often use (a Tamron 150-600mm lens). When I asked them how I could stop this from happening again, they suggested that I find a bracket that will tie the lens and the camera together.
Do pro Canon DSLRs have this problem? I have invested a small fortune in Nikon pro bodies, and Nikon and Nikon mount lenses, so I cannot afford to switch. This is a bad situation as I am a freelance columnist/photojournalist and have to pay for my camera gear and repairs myself.
This is not a normal problem at all, and unheard of with a D5 - how are you using this 150-600? If you are supporting the lens (and not the body) at all times, it's virtually impossible for that mount to bend in normal use. If you are hanging that large of a lens off the camera body like a cantilever, the shear strength is not nearly as high and that would likely be an issue. I also assume if using a tripod, you are using the lens with a proper lens foot and not the camera plate? I highly suspect it has to be something to do with how you use the combination, rather than a defective body.
