Cons: Sigma's definition of quality control is not the best, so you may need to have your lens calibrated to your specific body. Mine, for instance, came out of the package back-focusing slightly. Note- this doesn't effect manual focus.
Pros: Great geometry, F2.8 throughout the whole zoom range, and a solid finish.
Summary: I use this lens on my Sigma SD14. The combination of a lens and body both designed to detect great detail and produce sharp images sure is a winning combination.

Cons: Slightly front-focusing adjusted on the 50D
Pros: Value for money and build quality
Summary: Better than the Sigma 17-70 and Canon 17-85 so I'm happy for the money that I have spent.
