Sigma 120 300mm f28 EX DG OS HSM Canon Fit

The Sigma 120 300mm f2.8 EX DG OS HSM lens is a large aperture telephoto zoom lens featuring Sigma's optical Stabilisation system and weather resistant construction. One SLD and Two FLD glass elements are used for maximum correction of chromatic aberrations, while the Super Multi Layer lens coating reduces flare and ghosting. The improved optical design of the Sigma 120 300mm lens incorporates an inner focusing and inner zooming system to ensure sharp images throughout the entire zoom range and ensures ultra high resolution comparable to a fixed focal length lens. The Hyper Sonic Motor HSM ensures quiet and high speed AF and allows full time manual focus override. The rounded 9 blade diaphragm creates an attractive blur to the out of focus areas of the image. The Optical Stabilisation of the Sigma 120 300mm f2.8 EX DG OS HSM lens makes it possible to use shutter speeds approximately 4 stops slower than would otherwise be possible and enables hand held tele photography.
