Ronkonkoma, NY, Feb. 23, 2010 – Sigma Corporation of America (www.sigmaphoto.com), a leading researcher, developer, manufacturer and service provider of some of the world's most impressive lines of lenses, cameras and flashes, announced five new lenses and three new cameras, as well as its use of a new “F” Low Dispersion (FLD) lens glass, at this year’s PMA 2010 International Convention in Anaheim, Calif.

During the event, which took place between Feb. 21 and 23, Sigma Corporation of America unveiled the new 8-16mm F4.5-5.6 DC HSM, 17-50mm F2.8 EX DC OS HSM, APO 50-500mm F4.5-6.3 DG OS HSM, APO 70-200mm F2.8 EX DG OS HSM, 85mm F1.4 EX DG HSM, the DP1x and DP2s compact cameras and the SD15 digital SLR camera.

In addition to the new lineup of products, Sigma is pleased to announce the incorporation of its new FLD glass, which has a performance equal to fluorite glass, in three of its new high performance lenses. Four elements have been included in Sigma’s 8-16mm F4.5-5.6 DC HSM and two elements have been included in both the APO 70-200mm F2.8 EX DG OS HSM and the 17-50mm F2.8 EX DC OS HSM.

8-16mm F4.5-5.6 DC HSM

The Sigma 8-16mm F4.5-5.6 DC HSM is the first ultra-wide zoom lens with a minimum focal length of 8mm, designed specifically for APS-C size image sensors. This lens has an equivalent angle of view of a 12-24mm lens when used on digital cameras with an APS-C size image sensor. The wide-angle of view from 121.2 degrees* produces striking images with exaggerated perspective, enabling photographers to emphasize the subject. Four FLD glass elements, which have the performance equal to fluorite glass, compensate for color aberration. One hybrid aspherical lens and two glass mold elements give excellent correction for distortion and astigmatism. Incorporating an inner focusing system, the lens produces high-definition images throughout the entire zoom range. The Super Multi-Layer Coating reduces flare and ghosting while superior peripheral brightness ensures high contrast images throughout the entire zoom range. This lens incorporates Hyper Sonic Motor (HSM), ensuring quiet and high speed auto focus, as well as full-time manual focus capability. It has a minimum focusing distance of 9.4 inches throughout the entire zoom range, which allows photographers to emphasize the subject by creating exaggerated perspectives. This lens has a compact construction with an overall length of 4.2 inches and a maximum diameter of 2.9 inches.

*The angle of view varies depending on which camera the lens is mounted on.
