SIGMA 202109 / 202-109 10-20mm F3.5 EX DC HSM Super-Wide Angle Lens For Pentax 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.
Specification
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.
