Not to a point that anything has broken yet. (luckily)
But yes I have. To the floor at home. Against the side of a cliff,. (1D4 and the 400mm) etc.
I'd say my 1D2 has taken the most hits. Still going strong.
that 400mm is the lens that has taken the most beatings. And it started right from the get go. About two days after receiving my 400mm f/5.6L it was knocked to the floor off the kitchen table by my daughters best Friend. She is dead to us now. (Just kidding!)
The black plastic to which the lens hood clips into at the front was damaged, but otherwise the lens is still fine. I manage to bang that lens against something near every time I use it.
Well it's a long ass lens, so that's not farfetched.
Let's see. Oh. Not really a camera, but, the wind has knocked down my 430EX II from its stand about 200 times. Not a scratch. But I've probably had to buy about 30 umbrellas...
