SIGMA APO 120-300mm F2.8 EX DG OS HSM Announced

The Sigma Corporation is pleased to announce the new Sigma APO 120-300mm F2.8 EX DG OS HSM.

The successor to the APO 120-300mm F2.8 EX DG HSM, introduced to market in July 2005, this new lens offers the latest optical design technology.

This large aperture zoom lens features Sigma’s OS (Optical Stabilizer) function and weather-resistant design throughout for use in harsh conditions. One SLD and Two FLD glass elements are used for maximum correction of chromatic aberrations. The super multi-layer lens coating reduces flare and ghosting, and the lens design incorporates an inner focusing and inner zooming system to ensure sharp images throughout the entire zoom range. Improved optical performance provides excellent correction of sagittal coma flare, and ensures ultra-high resolution, comparable to a fixed focal length lens.

The OS function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. This system enables hand held tele-photography. Incorporation of HSM (Hyper Sonic Motor) ensures quiet and high speed AF, while allowing full-time manual focus override.

The rounded 9 blade diaphragm creates an attractive blur to the out of focus areas of the image. The addition of the optional APO TELE CONVERTER produces an ultra telephoto zoom lens with AF.
