This compact high zoom ratio lens is designed exclusively for digital SLR cameras and incorporates SigmaÕs original OS (Optical Stabilizer) function. This system 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 offers the equivalent of using a shutter speed approximately 4 stops faster. 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 lens coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. This lens has a minimum focusing distance of 35cm (13.8Ó) at all focal lengths, and has maximum magnification of 1:3.8, making it ideal for close-up photography. This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed autofocus.
