18-125mm F/3.8-5.6 OS HSM Lens f/ Nikon

This compact high zoom ratio lens is designed exclusively for digital SLR cameras and incorporates Sigma?s 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 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.
