I had a similar experience. Last winter I made the mistake of hanging my new white EOS M from my shoulder
(only had compact cameras in recent years (S95 and such) so was used to carrying from a wrist strap).
While I was securing my camera bag instead, the camera slipped off and went crashing onto a large jagged rock below. I was at Great Falls National Park by an overlook, very rocky!
In that split-second slow motion as I helplessly watched it fall, I expected destruction, but amazingly and thankfully it landed on a corner. There was a small ding in the body and a scrape revealing the metal below the paint. The 22mm lens didn't suffer any damage.
I was very upset and thoroughly annoyed with myself. Fortunately I have a lot of experience with various types of paint. So later I removed the lens, put on the lens body cap, very carefully and precisely masked the camera body with masking tape and paper. Then I feathered in white lacquer (automotive spray paint--can). After a day or so I put a coat of clear lacquer over it.
While it hacked me off to have to do this to a new camera, you wouldn't notice it with the naked eye unless you knew it and looked very closely. The finish is reasonably close in sheen.
Whew! That was a close one. But a testament to a well build camera.
I am much more careful now, to be sure.
