And I discovered another reason today.
D4, 1.7 TC, 300 f4 ended up between me and the ground in some non-olympian athletics!

D4 ... Ok, just a war scratch.
300 OK, dent on lens hood.

TC - stuffed. Lens-mounting ring distorted. D4 couples perfectly to all lenses and focus is spot on.

Lucky but maybe an argument for always having a TC!

When I got my gold medal in the D3/24-70 hurling event last year, the 24-70 disintegrated into several bits...but the mount stayed fixed and intact on the D3.

The lens was easily reassembled.

It made me wonder if there was a deliberate 'crumple-zone' in the modern lenses such that it sacrificially takes the impact in an area of least concern?
