150 OS :

The Sigma Corporation is pleased to announce the Sigma APO MACRO 150mm F2.8 EX DG OS HSM, a large aperture medium telephoto macro lens which incorporates Sigma’s original Optical Stabilizer function.

Successor to the APO MACRO 150mm F2.8 EX DG HSM, introduced to market in October 2004, this new OS design offers the latest optical technology. A floating focusing system moves two different lens groups in the optical path to different positions. This system compensates for astigmatic aberration and spherical aberration and provides extremely high optical performance from infinity to 1:1 Macro.

Three SLD (Special Low Dispersion) glass elements provide excellent correction of all types of aberrations and the Super Multi-Layer Coating reduces flare and ghosting. This lens has superior peripheral brightness and provides sharp, high contrast images even at the maximum apertures.

Equipped with Sigma’s proprietary OS (Optical Stabiliser) function, this lens offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. The HSM (Hyper Sonic Motor) ensures quiet and high speed autofocus as well as full-time manual focus capability.

This lens has a rounded 9 blade diaphragm creating a smooth blur to the out of focus areas of the image. It is also possible to use this lens with Sigma’s optional APO Tele Converters.

120-300 2.8 OS

The Sigma Corporation is pleased to announce the new Sigma APO 120-300mm F2.8 EX DG OS HSM, which offers improved optical performance. 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 performances 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 and 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 1.4x EX DG and 2x EX DG Tele Converters produces an ultra telephoto zoom lens with AF.
