Sigma 10-20mm f/3.5 EX DC HSM ELD SLD Aspherical Super Wide Angle Lens for Pentax Digital SLR Cameras

Product Description Sigma Corporation is pleased to announce the new Sigma 10-20mm F3. 5 EX DC HSM. This super-wide angle lens has a maximum aperture of F3. 5 throughout the entire zoom range. With its wide angle view from 102. 4 degrees it can produce striking images with exaggerated perspective. The maximum aperture of F3. 5 is ideal for indoor shooting and it enables photographers to emphasize the subject. Two ELD (Extraordinary Low Dispersion) glass elements and a SLD (Special Low Dispersion) glass element provide excellent correction of color aberration. Four aspherical lenses provide correction for distortion and allow compact and lightweight construction. The Super Multi-Layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. The incorporation of HSM (Hyper-Sonic Motor) ensures a quiet and high-speed auto focus as well as full-time manual focusing capability. This lens has a minimum focusing distance of 9. 4 inches (24cm) throughout the entire zoom range and a maximum magnification ratio of 1: 6. 6. The lens design incorporates an inner focusing system which eliminates front lens rotation, making the lens particularly suitable for using the Petal-type hood and polarizing filter. The Petal-type hood blocks extraneous light and reduces internal reflection.
