Camera autopsy. Interesting.

Interesting how ‘weak’ the lens mount is.

Something has to give, or both camera *and* lens are destroyed. Apparently the lens was unharmed, the camera obviously not.

Ideally the mount would be attached to a piece that sits in between and can be easily be exchanged (i e. not the mirror box a or large part of the front) after screws of the mount rips out and damages the threads. I vaguely remember such a construction used on some Nikon bodies, perhaps some of the later flagship D-bodies? This would be a good breakaway construction that would minimize damages should the worst happen.

I was among the first users of Z7 in NY. About 3 years ago I posted here - the lens mount is fragile. 4 bolts only without real reinforcing from inside. Second - the sensor needs to be covered while lenses change. So Nikon covers the sensor, but the mount is still the same. LZ

Obviously this has been quite a heavy impact to break off a huge chunk of magnesium, this was not "snap off" in any way or form!
This was a drop/impact with substantial energy, looks like a big heavy lens.
Magnesium is very stiff and quite strong, an extra 'tiny' mount screw would not have made much difference with such a high energy impact.
None of the Nikon DSLR has a mount break away design.
Some of the cameras are even space plastic for securing the mount,,, We had a long thread some years ago ;)
Some lenses has a break away ring near the lens mount, 24-70mm AFS f/2.8 for instance, that makes a clean cut, however you can often see the front group, zoom, suffer under impact - Keep your lens hood on at all times to minimize the risk of front group/zoom damage.

I can testify that even the chromed/painted brass bodies had breakaway lens mounts. Not intentionally, I'm sure. But I recall standing on the sidelines of a football game, holding my 180/2.8 lens with the front of a Nikon F2 attached while the remainder of the F2 was hanging sadly around my neck. Given persistence, I am able to break and destroy anything. ::) :P
