Bought a camera package online (first mistake) and the sales person convinced me that this was a good upgrade (second mistake, I believed him). Had the lens for about 6 months and it started grinding during focus. The extended warranty (third mistake) should have covered it but the underwriter went belly up. Took the lens to a camera shop and they said that it would cost more to fix it than its worth. Not a good first experience with Sigma Lenses.
