I'm looking to upgrade my Canon 18-55mm kit lens to the Sigma 17-70mm lens. It's a brighter lens with HSM motor and presumably better performance than the Canon kit lens. Also it has inner focusing unlike the kit lens which is a bit of a pain to use with a CPL as the filter rotates every time the lens re-focuses.
Has anyone had any experience with this lens ? Any comments on Sigma lenses in general ?
Cheers Dave
