This lens construction consists of one fluorite and five ultra-low dispersion optical elements which help deliver the sharpness and reduced aberrations. The IS II Optical Image Stabilizer provides up to 4 stops of correction at all focal lengths and features two modes for stabilization of still objects and while panning to follow moving subjects. An ultrasonic focusing motor provides fast, smooth and silent autofocus action.
