Large aperture ultra-telephoto zoom lens gives an equivalent field of view to 1600mm for the Four Thirds system.
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 autofocusing as well as full-time manual focus override. This lens is designed to accept a 46mm circular polarizing filter in a rear filter holder.
*With Four Thirds cameras the focal length will be equivalent to 600-1600mm.
