Oh I recall another one.. Just after buying my 10D and the 50mm prime, we had a lunar-eclipse (November last year if I recall correctly).. Guess it's big enough of a blunder to admit in here that I tried shooting the moon with a 50mm =D But.. there's more to it actually..
This was in the middle of the night. I took the camera, a tripod and drove off to the top of a mountain here, as I thought I could really get a good night-shot of the place where I live while at it. Up there, I placed the camera on the tripod, and took some shots. It was blowing a bit that night actually.. During one of those long exposures, I turned away from the camera to block the wind with my back as I lighted a cigarette. Upon turning back again, I saw the tripod falling forwards, headed for a sure death of camera/lens, as it would've felt off the mountain-cliff, and probably rolled 200-300 metres down on the rocky surface. In a miracoulos way, I manged to throw myself forwards, and get my hands on the tripod before it fell off. WOW! Talk about matrix-reflexes =D And to top it off, this was before I had fixed insurance for the equipment. If this was to happen again I would probably let it fall, and trow all my lenses and equipment (and probably car) after it, collect a nice insurance-check, and order a MK-II =D
