well.. I just experienced this horrifying feeling for the first time. Luckily it was just the rather inexpensive kit lens that came with my D50, but still.. I had packed some of my gear in the back of my car, and was driving up to my girlfriends apartment for the weekend. This being christmas time and all, I asked her to buy me a really sweet camera bag so that I can store everything in one place and have it all protected somewhat from accidents. So I am looking forward to arriving. Well, upon arriving, I carefully take out my camera with my 105mm macro lens attached, making sure not to drop it or anything. (it was sitting on top of some clothes that I had brought for the weekend). Then I go to take out the few clothes I brought with me which were folded neatly. Unbeknownst to me, my 18-55 lens had wiggled in between some of those clothes, and when I pulled the clothes out it goes tumbling out of my car and hits with a 'thump' on the ground. Its like one of those slow motion things when its happening, you are thinking the whole time 'oh ****, oh ****' please don't break. Won't you share your story as well..
