God, I must have a case of dropsy or something! This is the 3rd lens I've dropped now. Not to mention the 200-400 that won't work properly either! At least I didn't drop THAT one! The 12-24DX f4 Nikkor I just got from Dave here is broken. I was heading out to shoot the exotic cars Sat evening, and set the 12-24 of the hood of my car while I fumbled for my keys to unlock the car. Next thing I know, I hear "that sound", the sound of a lens hitting the pavement. It didn't even have a lens cap on it! The glass looked ok, but found out a bit later that it won't focus anymore, either in auto or manually, and has to go in for repair. Man, this hobby is expensive enough without having to send the equipment in for repair all the time!
