Sigma 120-400mm Canon Zoom Lens

The Sigma 120-400mm Zoom Lens incorporates Sigma's original OS (Optical Stabilizer) function. It offers the use of shutter speeds approximately 4 stops slower. Three SLD (Special Low Dispersion) glass elements provide excellent correction for chromatic aberration. This lens is equipped with a rear Focus system that minimizes the fluctuation of aberration caused by focusing. It provides optimum image quality throughout the entire zoom range. The super multi-layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. The minimum focusing distance of 150cm (59.1") throughout the entire zoom range and maximum magnification of 1:4.2 make it useful for close-up photography. This lens incorporates a Hyper Sonic Motor (HSM), which ensures a quiet and high-speed AF as well as full-time manual focusing capability. The addition of the optical 1.4x EXDG APO or 2x EX DG APO Tele Converters produce a 168-560mm F6.3-8 MF ultra-telephoto zoom lens or a 240-800mm F9-11 MF ultra-telephoto zoom lens respectively.
