The Sigma 18-250mm f/3.5-6.3 DC OS HSM wide-angle to telephoto zoom lens incorporates Sigma's Optical Stabilization (OS) and Hyper Sonic Motor. Sigma's anti-shake function provides not only an anti-shake function for the camera body, but also compensates for image shaking in the view finder as the Optical Stabilizer is built in to the lens. Special Low Dispersion glass elements and aspherical lens elements enables color correction aberration, while providing excellent image quality throughout the entire zoom range. Its super multi layer coating reduce the ghost in the backlight photography. An inner focusing system eliminates front lens rotation, making it suitable for use with circular polarizing filters and the supplied petal-type hood.
