The Sigma Corporation is pleased to announce the launch of the new APO 120-400mm F4.5-5.6 DG OS HSM for Sony and Pentax cameras.

This telephoto zoom lens incorporates Sigma’s original OS (Optical Stabilizer) function. It offers the use of shutter speeds approximately 4 stops slower. As compensation for camera shake is visible in the viewfinder, the photographer can easily check for accurate focus and ensure there is no subject movement. Three SLD (Special Low Dispersion) glass elements provide excellent correction for chromatic aberration. This lens is equipped with the rear focus system that minimizes fluctuation of aberration caused by focusing, providing optimum image quality throughout the entire zoom range.

The super multi-layer coating reduces flare and ghosting. The minimum focusing distance of 150cm (59.1”) throughout the lens’ zoom range produces a maximum magnification of 1:4.2, making it useful for close-up photography. This lens incorporates HSM (Hyper Sonic Motor) which ensures a quiet and high-speed AF as well as full-time manual focusing capability. The addition of the optional 1.4x EX DG 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 (For Sony fitting only).
