Photokina report
Sigma launched a new Four-Thirds system compatible, large aperture ultra-telephoto zoom lens; Sigma APO 300-800mm F5.6 EX DG HSM. This Sigma lens covers the equivalent field of view to 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.
