Lighter and more compact than its predecessor, Sigma’s updated 18-200mm lens features the company’s â€œFâ€ Low Dispersion (FLD) glass elements, which perform like fluorite glass and significantly improve lens performance. Ideal for beginner and professional photographers alike, this 11.1x highzoom ratio lens is designed exclusively for digital SLR cameras and incorporates Sigma’s Optical Stabilization (OS) system, which allows for high-performance, handheld, close-up photography. The lens also incorporates Sigma’s Hyper Sonic Motor (HSM) system to produce quiet, high-speed auto focus and includes the Super Multi-Layer Coating to reduce flare and ghosting. Its rounded sevenblade diaphragm creates an attractive blur to the out-of-focus areas of images. Visit www.sigmaphoto.com for more information and to locate an authorized Sigma dealer near you.
