Sigma announces the new Sigma 50-200mm F4-5.6 DC OS HSM. This compact high-performance telephoto zoom lens incorporates Sigma’s own Optical Stabilizer function. The Sigma 50-200mm 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 incorporation of HSM (Hyper Sonic Motor) ensures quiet and high-speed auto focus. The OS (Optical Stabilizer) 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 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 stabilization. The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images throughout the entire zoom range. The Sigma 50-200mm 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 polarizing filters.

The PMA show, or Photo Marketing Association, continues its yearly tradition of maintaining a network of photo imaging as well as the experience and know-how of the industry. The PMA represents 20,000 members from over 100 countries, who are all active within the imaging industry. As a reflection of the changes in the market, the PMA organization has also changed and has become more diverse. Nowadays, the member group consists of representatives coming from photo retail, manufacturers, commercial photo labs, professional sports and news photography, in addition to small album print suppliers and photo processing centers. The PMA 2012 Trade show focuses on an industry which is heavily affected by the unstable situation of the global financial economy. However, whether the latter will also stand in the way of the innovation and product introductions, remains to be revealed by the PMA International Convention & Trade Show in Anaheim Convention Center (California, US).
