Sigma announces the new Sigma 10-20mm F3.5 EX DC HSM lens. This super-wide angle lens has a maximum aperture of F3.5 throughout the entire zoon range. Its wide angle of view from 102.4 degrees produces striking images with exaggerated perspective. The maximum aperture of F3.5 is ideal for indoor shooting and it enables photographers to emphasize the subject. Two ELD (Extraordinary Low Dispersion) glass elements and a SLD (Special Low Dispersion) glass element provide excellent correction of color aberration. Four aspherical lenses provide correction for distortion and allow compact and lightweight construction. The Super Multi-Layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range.

The incorporation of HSM (Hyper Sonic Motor) ensures a quiet and high-speed AF as well as full-time manual focusing capability. The Sigma 10-20mm lens has a minimum focusing distance of 24cm (9.4 inches) throughout the entire zoom range and a maximum magnification ratio of 1:6.6. The Sigma lens design incorporates an inner focusing system. It eliminates front lens rotation, making the lens particularly suitable for using the Petal-type hood. The Petal-type hood blocks extraneous light and reduce internal reflection.

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).
