Sigma AF 300-800mm f/5.6 APO EX HSM Lens for Canon

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 6.9 at 300mm and 2.6 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.Coating reduces Ghost and FlareEquipped with ELD (Extra Low Dispersion) glass elementsHSM (Hyper Sonic Motor for Sigma, Canon and Nikon mount lenses)It also features a drop-in filterInternal Focusing and Internal ZoomingAccepts both 1.4X and 2X APO EX Tele-Converters300-800mm Lens4 Year Sigma USA Authorized Dealer WarrantyIn addition to the 1 year international warranty, when you register this EX lens with Sigma you will receive an extra 3 year extended warranty against defective materials or workmanship.
