Sigma APO 300-800mm f/5.6 EX DG HSM - From 300mm telephoto to 800mm ultra-telephoto this new lens provides a constant fast maximum aperture and is optimized for digital SLR cameras.
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 in situ. When this lens is used with the 1.4x EX or 2x EX Apo Tele Converters (optional), it becomes a 420-1120mmF8 MF lens or a 600-1600mm F11 MF lens respectively.
