Sigma 300-800mm F5.6 EX DG HSM 4/3
Launched September 2006
APO 300-800mm F5.6 EX DG HSM
Large aperture ultra-telephoto zoom lens gives an equivalent field of view to 1600mm for the Four Thirds system.
This large aperture ultra-telephoto zoom lens covers the equivalent field of view from 600mm to 1600mm when used on Four-Thirds cameras.
By continuously varying the angle of view, the lens takes a lot of the footwork out of picture composition. The very latest lens coating technology and lens design reduce flare and ghosting, a common problem with digital cameras. Two ELD glass elements in the front lens group reduce chromatic aberration to a minimum and also ensure high optimum image quality. The overall length of the lens does not change during focusing and zooming, ensuring convenient handling.
The HSM provides ultra quiet, high-speed auto focusing as well as full-time manual focus override. This lens is designed to accept a 46mm circular polarising filter in a rear filter holder.
