I got a Canon EF 35-70mm, f3.5/4.5 lens at a yard sale, cheap. Got it home and everything seemed to work as it should--focus and zoom-- but them I happened to shake it and it sounds like a bunch of beads (bearings?) rattling around. Am I correct in thinking it will fit my waste basket better than a camera? I don't have a Canon to try it on.
Don't judge a lens by how it sounds.
