AF 10-20mm f/3.5 EX DC HSM Lens for Sigma

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.

A little about Macro Lenses

Macro lenses are important to photographers who tend to shoot close-ups. That’s because, although they’re quite similar to standard lenses in most ways, macro lenses are engineered to focus at much shorter distances. Most often used in nature photography, these lenses magnify small objects like insects and flowers and captures immense detail and clarity. Other applications of a macro lens are in scientific photography and product photography. You’ll find that macro lenses can also act as a standard lens.

These lenses tend to have a higher f-stop number (which allows in less light) and therefore are not always ideal in low lighting situations. For subjects that are sensitive to movement (insects and animals, for example), macro lenses with longer focal lengths can be used.
