Sigma 50-500mm f/4.5-6.3 APO DG OS HSM Lens for Canon
The Sigma APO 50-500mm f4-6.3 EX DG HSM Lens for Canon Digital SLR Cameras is a high-magnification zoom lens with a 10x zoom ratio and is available from Outdoorphoto. The advanced optical design of the lens is optimized for digital SLR cameras, and the super coating on each glass surface produces superb color rendition, while reducing flare and ghosting. The Hyper Sonic Motor provides quiet high-speed AF function, as well as full-time manual focus capability. When the lens is set to the 50 millimeter focal length, it is compact and provides easy handling. The tripod mount is composed of magnesium, to minimize total weight. It is also easy to grip and carry the lens due to ergonomic design of the tripod mount. Non-rotating front lens elements, due to the rear focus mechanism, make possible the use of a custom bayonet "petal-type hood," which prevents extraneous light from degrading the image quality.
