I dropped my Rebel XTi once..
I was at an airshow and the planes had landed, so I went to switch from my 75-300 to... can't remember... something else. Anyway, my girlfriend at the time stood up and knocked my gatorade bottle off the table towards where I had the camera. So I tried to move it out of the way of the spill but it slipped, me holding the lens in one hand and the strap in the other (but the strap was long enough where it still made it to the ground, so I guess the drop was way less than 2 feet). The camera fell down, the bottle rolled on its side and spilled all over the camera anyway (gahhhh!). [I kepted the camera, but traded in the girl. Hooo snap!]
Double whammy on damage, sticky fluid and a nice big scuff in the corner. Ever since then (years ago), when it gets really cold and I'm not actively using the camera, all of the buttons on the right side on the back are a little sticky, and the dial takes a few back-and-forths to loosen up. When it's warm it's not even noticeable... which is strange that it hasn't gone away eventually living in the heat down here in GA and Florida. Luckily none of my lenses were involved (I like those more than my rebel body haha).
But hey, to be honest, there is just no way that my Rebel Xti should have lasted this long. I mean actuation wise it's probably not crazy (somewhere around 20,000 I'd guess, not a lot but I think the rebel shutter is only rated to 35K or so), but it's been to some crazy places. It's been scuba diving, I skied with it a few times, I took it to hawaii which included both volcanoes and rented telephotos (which my brother and I traded off camera duty while surfing so we could get pictures of ourselves riding [tons of sand!]), Ireland where it rained a ton (actually it was nice the first few weeks but afterwards.. yeah), and like a billion football games and other college sports events when I worked for the paper.
I can't believe it's still clicking, however my brother's camera, which we got at the same time but has seen a lot less use, just feels better to use... like the actuation of the mirror and shutter just feel more solid and precise. It probably doesn't make any sense, and the pictures they take look the same, so maybe it's just me.
