Sigma 18-200mm lens features
Aspherical lenses give excellent correction for all types of aberration and distortion. The Sigma 18-200mm lens offers Super Multi-Layer Coating reducing flare and ghosting, ensuring high quality images throughout the entire zoom range. Sigma’s OS (Optical Stabilizer) system offers effective correction of approximately 4 stops, enabling easy handheld photography. The Sigma 18-200mm lens also offers HSM (Hyper Sonic Motor) ensuring quiet, high-speed auto focus. The inner focus system eliminates front lens rotation, making the Sigma lens particularly suitable for using the supplied petal-type lens hood and circular polarizing filters. The rounded 7 blade diaphragm of the Sigma 18-200mm lens creates an attractive blur to the out of focus areas of images.
