PMA, Las Vegas - March 2nd 2009. Sigma have announced three new DC lenses for 2009, with significant improvements for the entry-level range and for one established favourite.The 50-200 features optical stabilisation and aspherical elements in what should prove to be a lightweight, low cost successor to the 55-200. Bringing HSM to all mounts which support it, this should prove to be a popular lens on non full-frame DSLRs. Read more for the press release and images.
50-200mm F4-5.6 DC OS HSM
Telephoto zoom lens with Optical Stabiliser and high speed AF  The Sigma Corporation is pleased to announce the new SIGMA 50-200mm F4-5.6 DC OS HSM.
This compact high-performance telephoto zoom lens incorporates Sigma’s own Optical Stabiliser function. The lens incorporates SLD (Special Low Dispersion) glass in the front lens group and is equipped with an inner focusing system to provide high image quality throughout the entire zoom range. The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images.
The incorporation of HSM (Hyper Sonic Motor) ensures quiet and high-speed auto focus. The OS function effectively eliminates the effects of camera shake so subjects can be easily and clearly seen in the viewfinder as well as in the image. It allows the use of shutter speeds approximately 4 stops slower than normal for steady, handheld photography. For Sony and Pentax mounts he built-in OS System operates in conjunction with a camera body equipped with an anti-shake function and can be used as an alternative with cameras having built-in image stabilisation.
This lens has a minimum focusing distance of 110cm (43.3 inches) throughout the entire zoom range and a maximum magnification ratio is 1:4.5. An inner focusing system eliminates front lens rotation, making it suitable for use with circular polarising filters. Specifications:
