This looks interesting :D
An ultra-telephoto zoom lens, which overcomes image blur caused by camera shake.
Sigma APO 80-400mm F4.5-5.6 EX OS is one of several new products introduced at Photokina 2002 by Sigma Corporation of Japan (2-3-15, Iwado-Minami, Komae-shi, Tokyo, Japan).
Sigma's OS (Optical Stabilizer) system detects camera shake by utilizing two sensors, and then by the movement of an optical stabilizing lens group. It is equipped with two optical stabilizer modes to compensate for image blurring.
Mode 1, determines the camera shake in vertical and horizontal panning and compensates blurring, this mode is effective when shooting static subjects.
Mode 2, detects the vertical camera shake, and overcomes blurring. It is especially effective with moving subjects such as motor sports etc.
