So I dropped my 70-200mm a couple of weeks ago...it worked right away afterwards, but a couple of days later there was no AF (which means I must have banged it again after shooting the last event, but I don't recall doing that). I sent it into a Sigma repair center in Arizona. Got quoted for $180 to repair. Nervous after they said they had to order the parts from Sigma Japan (!) and that it may take 15-20 business days to repair (!!). Just now someone called and said that Sigma Japan didn't have the parts and that they would be sending the lens back to me not repaired (!!!).
For the record, the lens is a Sigma 70-200mm f/2.8 EX lens, bought it from a friend about two years ago. I had no idea that the lens was apparently already obsolete.
So the question is, really - what should I do now? if Sigma can't do it, nobody can? Should I pick up a brand new 70-200mm to avoid the "no parts" problem? ideally, I would probably pick up a Canon lens...cheaper to drive down to Irvine than it is to spend $10 each way shipping to Arizona. but now I'm kinda paranoid that Canon will not service the lens when I run into trouble.
