Just posted! Our lens review featuring the first image-stabilized fast telezoom to appear from an independent lens maker: the Sigma 70-200mm 2.8 EX DG OS HSM. With an all-new optical design and Sigma's silent ultrasonic-type HSM focusing, it offers an interesting alternative to Canon and Nikon's latest designs at an attractive price, while providing Sony and Pentax users with the option of using in-lens stabilization.This is all pretty compelling on paper, so how well does it work in practice?
