Sigma 120-300mm features
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 on the Sigma 120-300mm lens 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 Sigma APO 120-300mm lens has a rounded 9 blade diaphragm creating 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 auto focus.
