This Sigma lens is the world’s first ultra telephoto zoom lens that offers a fast aperture of F2.8 at the 500mm focal length and F5.6 at the 1000mm. It covers widely used focal lengths from 200mm to 500mm and has a large aperture of F2.8 throughout the entire zoom range. The Sigma APO 200-500mm F2.8/400-1000mm EX DG lens can be used to create amazing image expression with various types of photography such as astrophotography, portraits, wildlife, sports. SLD (Special Low Dispersion) glass and three ELD (Extraordinary Low Dispersion) glass elements provide excellent correction for all type of aberrations. The super multi layer lens coating reduces flare and ghosting.

The lens hood, designed exclusively for this lens, blocks out extraneous light. A 72mm filter can be inserted at the rear of the lens, and a circular polarizing filter can be used in situ thanks to the ingenious internal rotation mechanism. The dedicated Li-ion battery BP-21 is used to power the zooming and AF operation. This battery is built in the lens barrel. For the convenience of the photographer, focusing distances and focal lengths can be viewed on the lens`s built-in LCD panel.

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).
