SIGMA APO 120-300mm F2.8 EX DG OS HSM

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.

Briefs:
– Designed for use with full frame digital SLR cameras. May also be used with smaller APS-c size sensors
– Weather resistant feature protects the lens from the effects of harsh weather conditions
– Offers Sigma’s OS System (Optical Stabilization) allowing handheld photography even in low-light situation
– HSM (Hyper-Sonic Motor) ensures a quiet & high-speed auto focus
– FLD glass elements with performance equal to fluorite glass for compensate for color aberration

This lens was launched  elsewhere in Sep 2010, should reach our shores Q1 2011.
