The SIGMA 60-600mm F4.5-6.3 DG DN OS | Sports is designed to be the one essential lens for travel, outdoor. Sports, wildlife, and safari that can cover it all from standard to ultra-tele, plus close-ups, all without ever swapping lenses; and it offers an impressive 6 stops of Optical Stabilization at the telephoto end and 7 stops at the standard end. The newly designed HLA (High-response Linear Actuator) focusing motor delivers unprecedented fast and precise autofocusing, and dual action zoom allows for both the precision of the zoom ring and the swift, intuitive response of the push-pull action on the front end of the barrel. The three AFL buttons are easy to operate in any orientation, and the Zoom Lock switch can be locked at all marked focal distances. #sigma #newsigma #newproduct #sigma60600mmsports
