 Sigma 300-800mm APO F5.6 EX DG lens introduction : Sigma Corporation is pleased to announce the launch of the new APO 300-800mm F5.6 EX DG HSM lens. This digitally optimized lens covers the ultra-telephoto range up to 800mm and has a fast maximum aperture. Its new lens coating reduces flare and ghost, which is a common problem with digital cameras. It incorporates two ELD glass elements for effective compensation of chromatic aberrations and also ensure sharp, quality images. Since focusing and zooming do not change its overall length, this lens offers ease of handling and operation. The HSM ensures a quiet, high-speed AF function as well as full-time manual focusing capability for Sigma, Canon, and Nikon mount lenses.
