Not today, but a few months back I dropped my Nikon 70-200 VR. I had my F5 around my neck and when I removed the lens I grabbed it just right, on the focus ring, it rotated out of my hand and onto the concrete. Luckily I had the shade attached as it landed on the tripod foot, bounced up and hit again on the hood.
The only damage is a bent plate where the barrel and tripod plate meet and a scuffed hood. Works fine, just can't use it on a tripod
