Mine jumped out of the back seat of my truck and onto pavement... it became 2 pieces...
my friend had his mounted to his camera... camera hanging at his neck... someone walked by and tripped, momentum carried him into my friend, and in the process managed to impact the camera somehow... there didn't appear to be any problems, my friend was able to shoot, focus was ok, etc... but about an hour later, the front element part of it just fell out...
It's a good little lens, you can't do better for the $$... but gravity is a terrible enemy to have...
