I went out this afternoon with my Canon 5D III and 70-200 F2.8 II to take some Boston shots after the snow storm yesterday.
Since this setup is pretty heavy (5D is gripped, with L bracket), I attached my BR strap to the lens.
I was walking around, and everything was fine, when all of a sudden, somehow, the lens release must have been pushed rubbing up against my side, or my hand, who knows...
The 5D body fell off the 70-200, right onto the wet brick sidewalk. It made the worst sound possible, and some lady had a more horrified look on her face then I did. My screen protector flew off the camera.
Fortunately it landed on it's back. Nothing entered the camera mirror box area that I can see.
Miraculously, the camera still works. But, there is a big crack in the chassis up near the focus point button, and the LCD cover for the info window was damaged as well. I drove directly to the local camera shop, and off to Canon it is going. It looks like damage should be limited to about $250.
Now I can't really truly blame the black rapid, since the strap and mechanism didn't fail. I've been using a black rapid for a couple of years now without a problem... but this is surely something to be careful about!
I thought surely I had just destroyed a $3500 camera...
