Sigma For Canon 10-20mm F/3.5 EX DC HSM
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.
