Sigma APO 300-800mm F5.6 EX IF HSM provides a constant F-number from 300mm telephoto to 800mm ultra-telephoto. This super-telephoto zoom lens has a horizontal angle of view of 6.9º at 300mm and 2.6º at 800mm. Its ability to zoom from a fixed position offers unparalleled versatility in composing an image. It incorporates two pieces of ELD (Extraordinary Low Dispersion) glass in the front for effective compensation of chromatic aberration. 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. A 46mm filter can be inserted near the rear of the lens, and a circular polarizing filter can be used. The lens materials used in this new lens are lead and arsenic free ecological glass.
