One of the first lenses I bought when I got my first dSLR was a Sigma 28-70. Ended up selling it because I decided to step into something different but the guy I sold it to bought it because I still had the warranty card. The copy I had had some softness to it. He planned to send it back to Sigma to try to resolve it.

Why must you tempt us with this?!
