Sigma Corporation is pleased to announce the launch of the new APO 300-800mm F5.6
EX DG HSM lens.
This digitally optimized lens covers the ultra-telephoto range up to 800mm and has a fast
maximum aperture. 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.
