It is equipped with Sigma’s own one-of-a-kind technology OS (Optical Stabilizer) function. This function uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilizing lens group, to effectively compensate for camera shake. It also automatically detects movement of the camera and compensates for camera shake when shooting moving subjects such as motor sports. SLD?Special Low Dispersion?glass and three aspherical lenses provide excellent correction for all types of aberrations. The super multi-layer lens coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. This lens has a minimum focusing distance of 45cm (17.7”) at all focal lengths, and has maximum magnification of 1:3.9, making it ideal for close-up photography. The incorporation of HSM (Hyper Sonic Motor) grants quiet and high-speed autofocusing with all Nikon DSLR cameras. An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using circular polarizing filters and the petal-type lens hood supplied.
