PMA News - The Sigma Corporation is pleased to announce the new Sigma APO 70-200 F2.8 EX DG OS HSM lens. This large aperture telephoto zoom lens incorporates Sigma’s original Optical Stabilizer function. The Sigma 70-200mm lens covers a medium telephoto range of focal lengths from 70mm to 200mm and has a large maximum aperture of F2.8 throughout the entire zoom range. 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.

Sigma 70-200mm lens specifications
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. Two FLD (“F” Low Dispersion) glass elements, which have the performance equal to fluorite glass, and three SLD (Special Low Dispersion) glass elements provide excellent correction of color aberration. High image quality is assured throughout the entire zoom range and an optimum optical power layout provides superior optical quality in all shooting ranges from close-up to infinity. Super Multi-Layer Coating reduces flare and ghost.

Focusing distance of the Sigma 70-200mm lens
The Sigma 70-200mm lens incorporates HSM (Hyper Sonic Motor), ensuring a quiet and high speed AF as well as full-time manual focus capability. The new Sigma lens has a minimum focusing distance of 140cm (55.1”) throughout the entire zoom range and a maximum magnification ratio of 1:8. The rounded 9 blade diaphragm creates an attractive blur to the out of focus images. The Sigma 70-200mm lens is equipped with a Petal-type hood. For digital cameras with an APS-C size image sensor, a dedicated hood adapter, which expands the length of the lens hood, is supplied.

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).
