The Sigma 70-200mm f/2.8 EX DG APO OS HSM for Sony is the second generation of large-aperture telephoto zoom lenses incorporating Sigma's OS (Optical Stabilizer) anti-shake system. It offers the equivalent of shooting at shutter speeds 3 to 4 stops slower than without OS, thus allowing handheld telephoto zoom shooting even in poorly lit conditions. Its HSM ensures quiet and high speed AF as well as full-time manual focusing.
