Its new lens coating reduces flare and ghost, which is a common   problem with digital cameras. It incorporates two ELD (Extraordinary Low Dispersion)   glass elements for effective compensation of chromatic aberrations and also ensure   sharp, quality images.   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.   Download from Www.Somanuals.com.
