I dropped my 18-105 from waist height it bounced a few times still works fine...(not a multi thousand dollar lens but that my contribution)
Question for you guys... just purchased a 28mm F2.8D lens from a guy on POTN he said the aperture blades were stuck at 4.5 and they are (got the lens for 60) well inspecting the lens seems like there is a oily substance inside the lens causing the blades to be sticky has this happened to any one? The AF works so i dont think its water damage any thought's? Im taking it to a service shop tomorrow which was my plan to do im thinking i can have a good lens for under 150
