PMA 2010 - The Sigma Corporation is pleased to announce the new Sigma APO 50-500mm F4.5-6.3 DG OS HSM lens. This is a 10x high zoom ratio ultra telephoto zoom lens incorporating Sigma’s original Optical Stabilizer function. The Sigma 50-500mm lens covers a wide range of focal lengths from 50mm to 500mm ultra telephoto. The OS (Optical Stabilizer) function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible. For Sony and Pentax mount, the built-in OS function of this lens can be used even if the camera body is equipped with an image sensor shift anti-shake system. As compensation for camera shake is visible in the view finder, the photographer can easily check for accurate focus and ensure there is no subject movement.

Four SLD (Special Low Dispersion) glass elements provide excellent correction of color aberration. The Super Multi-Layer Coating reduces flare and ghost and ensures high image quality throughout the entire zoom range. The Sigma 50-500mm lens has a maximum magnification ratio of 1:3.1 (at the focal length of 200mm) making it ideal for close-up photography.

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).
