Strength:

Weakness:

Weight, price, poor AF accuracy, cheap build quality

Well, I had a bad luck with no HSM version, but I decided to try this one.

I did an autofocus accuracy test on my 30D, and also compared with my Canon lenses. The sigma lens consistently front-focused, and the error margin was significant. While all of my Canon lenses were nearly perfect at close focus distances.
Since the AF issues are present I decided to get Canon 24-70mm. It is far better, yet I need 5D to realize its full potential.

At this price, this lens is a waste of money and time.

Customer Service

I spoke to Sigma representatives at the exhibition about their issues, and they couldn't answer me anything, just told me to get Canon lens. It was truly their best advice to date.
