Sigma reveals 18-200mm F3.5-6.3 II DC OS HSM


The Sigma Corporation is pleased to announce the release of the SIGMA 18-200mm F3.5-6.3 II DC OS HSM. This 11.1x high zoom ratio lens is designed exclusively for digital SLR cameras, incorporates Sigma’s original OS (Optical Stabiliser) function and offers a broad shooting range from wide angle to telephoto.

The SIGMA 18-200mm F3.5-6.3 II DC OS HSM is the successor to the SIGMA 18-200mm F3.5-6.3 DC OS/ HSM which was launched in June 2007. The 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. Aspherical lenses give 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 Stabiliser) 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.

*Sony and Pentax mounts do not incorporate Optical Stabilisation.
