From my engineering background, and looking at the photos provided, the actual eyelet anchor assembly that goes into the camera seems to have a hole in it, where it seems there could or should also be an anchoring pin, or other method, assisting with the security of that eyelet assembly to the camera body. A possible pin appears to be missing, or other method of security of that eyelet assembly, and thus possibly why it came adrift from the camera more easily in this particular case. Just a thought. To pull the eyelet out of the camera with an anchoring pin would take a very considerable force and destroy the area around the eyelet anchor point of the camera body and I doubt very much that it was just merely had a lens attached and that combined weight pulling the eyelet anchor from the camera whilst carrying it around. It looks to be more to this than what there appears, IMO. It looks like there was possibly some yanking force going on or the strap became caught on something and the owner pulled at it not realising it had possibly become snagged, not just the weight of a lens and carrying it around. However, if there is a pin that goes though the eyelet and that pin was missed during the construction of a particular camera (or dare I say batch of cameras) then it would be much easier to remove the eyelet assembly as the eyelet assembly is relying on the plastic "adhering or gluing itself" to the eyelet assembly shaft which is smooth due to the chrome plating and would thus have little adherence and thus come out quite easily. I would dare say with the way it is shown that there will be many more failures if it is indeed engineered this way, which I do not believe it would be. The point I am making is that the way the eyelet assembly is being shown in the photos really looks way under-engineered for such a duty and I can't believe that Nikon, or any decent engineer, would design it in such a way. If the anchor point assembly of the eyelet and camera is supposed to be able to take the weight of a lens and camera body, say the Z8 + 800 f.56 lens, the heaviest Nikon lens I know of, then it would be designed to take at least the combined weight plus 2.5 times that. It seems as though there is something missing from manufacture of that particular camera, like the aforementioned pin or other anchoring method to keep the eyelet assembly in place, or that there is something missing from the owners photos - did a part get lost like a pin through the eyelet assembly as I have postulated?
