Sigma APO 120-300mm f/2.8 EX DG OS HSM Lens Press Release

Sigma APO 120-300mm f/2.8 EX DG OS HSM Lens

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

This new lens incorporates Sigma’s proprietary Optical Stabilizer system, and offers high image quality. In addition, this lens features splash proof design for use in harsh conditions. One SLD and two FLD glass elements are used for maximum correction of chromatic aberrations. The Super Multi-Layer 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 (Optical Stabilizer) system 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 autofocus, 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 Sigma’s APO TELE CONVERTER produces an ultra telephoto zoom lens with AF.

Case, Bayonet type Hood (LH1128-01), Tripod socket TS-31 supplied.

* Nikon mounts do not have an aperture ring. Some functions may not work depending on the camera model.

* For Nikon and Canon mounts, Optical Stabilizer (OS) function will not work with film SLR cameras except Nikon F6 and Canon EOS-1V.

* FLD glass is the highest level low dispersion glass available with extremely high light transmission. This optical glass has a performance equal to fluorite glass which has a low refractive index and low dispersion compared to current optical glass. It also benefits from high anomalous dispersion. These characteristics give excellent correction for residual chromatic aberration (secondary spectrum) which cannot be corrected by ordinary optical glass and ensures high definition and high contrast images.
