The Sigma18-200mm F3.5-6.3 II DC OS HSM lens is ideal for travel photography with a compact construction and length of just 87.7mm.

This lens features FLD ("F" Low Dispersion) glass elements, which have the performance equal to fluorite glass and SLD (Special Low Dispersion) glass elements providing excellent correction of color aberration. This Aspherical lens gives excellent correction for all types of aberration and distortion. The Super Multi-Layer Coating reduces 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. HSM (Hyper Sonic Motor) ensures quiet, high-speed auto focus and the inner focus system eliminates front lens rotation, making the lens particularly suitable for using the supplied petal-type lens hood and circular polarizing filters. The rounded 7 blade diaphragm creates an attractive blur to the out of focus areas of images.
