This lens was bought new and is in excellent condition EXCEPT the lens hood has a crack in it and will not hold onto lens securely (see photo).  Lens hood slipped off the lens and hit the ground and I stepped on the hood. Lens is very flimsy to begin with.  Might be able to glue it or buy new one. 

This lens was kept in smoke and pet free environment when not being used.  Reason I am selling is because I am switching camera systems.    Good Luck!
