Description: Fix the APO 50-500 mm F4-6.3 EX DG/HSM Telephoto Zoom Lens from Sigma to your Camera and capture high-quality close-up shots. This lens uses four pieces of SLD (the special low dispersion) glass for excellent correction of color aberration throughout the entire zoom range. The incorporated Hyper Sonic Motor (HSM) provides quiet high-speed AF function, as well as full time manual focus capability. It has Non-rotating front lens elements due to rear focus mechanism, 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. In addition, the super coating on each glass surface produces excellent color rendition, while reducing flare and ghosting. This lens is specifically designed for Select Canon Mounts. Minimize
