Sigma 80-400mm F4,5-5,6 DG EX OS (Canon) Black

80-400mm F4,5-5,6 DG EX OS (Canon) Optical Stabilizer (OS) function, developed with Sigma's own technology, compensated for shaking of the camera.
Using Sigma's original OS (Optical Stabilizer) function, two types of sensors inside the lens detect vertical and horizontal movement of the camera. To deal with all kinds of photographic situations, the system has two camera-shake compensation mode:1 which detects and compensates for both vertical and horizontal movement, and 2 which compensates for vertical movement only.
This lens has two SLD (Special Low Dispersion) glass elements in the front lens group and one in the rear lens group for correction of chromatic aberration throughout the entire zoom range.
