Improved optics from the non-OS version: Sharpness at 200mm improved two levels in our test and beat most of the competition. Optical stabilizer gained 2 to 3 stops in handholdability.
Sigma's long-awaited, second Optical Stabilizer (OS) lens ($549, street) is an 11.1X digital-only superzoom with one SLD and three aspheric elements. A 29-320mm equivalent, it follows Sigma's first OS lens, an 80-400mm f/4.5-5.6 ($999, street), by more than four years, and outdoes its predecessor with a sophisticated new autopanning sensor that detects extended lateral movement, then engages only the vertical stabilizer to allow blur where you want it.
