10-20mm f/4-5.6 EX DC HSM
FEATURES
OVERVIEW

This ultra-wide zoom lens has a wide angle of view from 102.4 - 63.8 degrees (when Sigma mount is used) and it is exclusive to digital
SLR cameras. SLD glass elements effectively compensate color aberration. Aspherical lenses provide maximum correction for distortion
and various aberrations; high image quality is displayed throughout the entire zoom range. The HSM equipped models makes fast AF
speeds and quiet shooting a reality, and it is also capable of full-time manual focus. It has a minimum focusing distance of 24cm (9.4”) at
all focal lengths. It is also equipped with an integral Petal-type hood to block out extraneous light.

KEY FEATURES

Ultra-wide zoom lens

10-20mm F4-5.6 EX DC HSM lens allows enjoyment of super wide-angle photography and it is a very powerful tool for indoor shooting and
landscape photography with APS-C size image sensors of digital SLR cameras.
Wide angle of view 102.4-63.8 degrees (for Sigma mount)
offers the photographer greater freedom of expression.

Most Appropriate Coating for Digital SLR Cameras

The new multi layer lens coating and lens design reduce flare and ghost, which is a common problem with digital cameras and also
creates an optimum color balance through the entire zoom range.

The best possible correction of aberrations

Three SLD (Special Low Dispersion) glass elements are employed for effective compensation of color aberration, which is a common
problem with super-wide angle lenses. One piece of glass mold and two hybrid aspherical lenses, offer excellent correction for distortion,
as well as all types of aberration.

Inner focus system

This lens incorporates an internal focusing system, which eliminates front lens rotation allowing the use of a Petal-type Hood and also
minimize fluctuation of aberration caused by focusing system

HSM(Hyper Sonic Motor)

The HSM equipped models ensure a silent, high-speed AF function as well as full-time manual focusing capability for Sigma, Canon, and
Nikon-D mount lenses.

Minimum focusing distance of 24cm (9.4”) at all focal lengths

This lens has a minimum focusing distance of 24cm (9.4”) throughout the entire zoom range.
