Features

The Sigma APO 50-500mm F4-6.3 EX DG HSM is a high zoom ratio lens that is optimized for digital SLR cameras and capable of covering a wide range of focal lengths from 50mm standard to 500mm ultra telephoto. It features super coating on each glass surface produces color rendition, while reducing flare and ghosting, SLD glass for optical performance that utilises four pieces of SLD (the special low dispersion) glass for correction of color aberration throughout the entire zoom range, HSM (Hyper Sonic Motor) for quiet high-speed AF function, as well as full time manual focus capability and APO Tele-Converter EX (optional) that allows users to use this lens as a 140-700 mm F7.3-8.8 MF ultra-telephoto zoom lens with a 1.4X EX teleconverter, or as a 200-1000mm F10.4-12.6 MF ultra-telephoto zoom lens with a 2X teleconverter (Teleconverters can be used in 100mm – 500mm focal length range). This lens also features a Zoom Lock device to eliminate “Zoom Creep” when the lens is tilted down. The tripod mount is composed of magnesium, to minimize total weight and also it is easy to grip and carry the lens due to ergonomic design of the tripod mount. This lens has non-rotating front lens elements, due to rear focus mechanism that make is possible to use a custom bayonet “Petal-type Hood” with the lens, which prevents extraneous light from degrading the image quality. This mechanism also allows the use of circular polarizing filters, since the front barrel does not rotate during focusing or zooming.
