This lens is garbage.  The SDM is poorly designed and it predictably fails just after a year of normal usage.  This is a well known issue and has happened to many users. I sent it for service after the warranty expired and paid over $200 to have it fixed, then guess what?  A little over a year later if failed again! Optically the lens is great.  It just does not work.  If you are thinking about getting one, buy the longest extended warranty you can get or even better yet don't.  Get a Tamron ...
