Lens Description: The Sigma 18-125mm f/3.8-5.6 DC OS HSM is a high ratio zoom lens which is designed exclusively for digital SLR cameras This compact high zoom ratio lens incorporates Sigma\'s original OS (Optical Stabilizer) function. This system uses two sensors inside the lens to detect vertical andhorizontal movement of the camera and works by moving an optical image stabilizing lens group to effectively compensate for camera shake. It offers the use of shutter speeds approximately 4 stops slower. It is the ideal lens for several type of photography such as wide-angle, telephoto and close-up. SLD (Special Low Dispersion) glass, a molded glass aspherical lens and two hybrid aspherical lenses provide excellent correction for all types of aberrations. The super multi-layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. This lens has a minimum focusing distance of 35cm
