Hello everyone! Over the weekend, I was shooting sports with my Canon 1D X and had it mounted to a 400mm f/2.8 IS II, handholding and sometimes using the monopod.
A friend was at the game, so I walked away for a minute to get a drink, and told him he could handhold it and shoot some photos if he wanted to. When I came back, I saw him holding the entire setup by the camera body alone while he was looking through the menus on the back of the camera! I jogged up to him to tell him not to hold the body and lens by the camera body alone, and to support the lens at all times so the bayonet mount doesn't deform or break.
My main worry was whether anyone had heard of this kind of treatment resulting in an actual EF mount on the camera or lens breaking, or warping so that lenses are loose or there are light leaks, or somewhere down the line I have a bayonet mount that needs replacement from fatigue. Any experiences or eyewitness accounts are appreciated.
I've heard some people say that the bayonet mounts are rock solid, both on the lens and the camera bodies, but I just wanted to hear from some people in here.
