Canon 10-22 vs Sigma 10-20 test
Another common question is which one of these should I get? I decided to check both out for myself.
Sharpness: When shot in RAW, Sigma is a touch sharper in the center and corners. If you process, it's not a factor.
CA: Canon has a touch more.
Flare: Cannon seems to handle flare better with more contrast.
Handling: Canon is lighter and feels cheaper, but it has a slightly faster and quieter AF. Sigma is heavier and has damped rings, also comes with a hood and a bag.
