Key Features: Sigma 10-20mm F/3.5 EX DC HSM Lens - Canon Fit
Ultra wide-angle zoom
The 10-20mm F3.5 EX DC HSM lens offers photographers greater freedom of expression by rotating the zoom ring. It is a very powerful tool for architectural, indoor and landscape photography.
This ultra-wide-angle lens allows photographers to create an exaggerated perspective between the subject and the background to emphasize, for example, expanses of a landscape.
Large F3.5 aperture throughout
The large, constant aperture of F3.5 provides a bright image in the viewfinder, which helps photographers easily check focusing and composition.
Superior image quality
Two ELD (Extraordinary Low Dispersion) and one SLD (Special Low Dispersion) glass elements are employed for effective compensation of colour aberration. The use of two glass mould and two hybrid aspherical lenses offer excellent correction for distortion and astigmatism and assure superior image quality. The super multi-layer coating reduces flare and ghosting and provides high contrast images throughout the entire zoom range.
Quiet and fast AF
This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed auto focus as well as full-time manual focus override by rotation of the focus ring.1
(1. AF will not function with Pentax *ist series and K100D DSLR cameras that do not support HSM.)
An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the included petal-type lens hood which blocks out extraneous light.
Minimum focusing distance of 24cm (9.4")
This lens has a minimum focusing distance of 24cm (9.4 inches) throughout the entire zoom range. This close focusing distance on such a wide-angle lens emphasizes perspective and allows the photographer to capture high quality images, not only of the foreground subject but also the surrounding scenery.

Sigma Lens Abbreviations:
EX (EX Lens)
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.
DC (DC Lens)
Sigma's DC lenses are designed for cameras with a cropped sensor. Do not put a Sigma DC lens on a camera with a full-frame sensor, such as the 5D Mark III. These are special lenses designed so that the image circle matches the smaller size of the image sensor of most digital SLR cameras. Their specialised design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus.

This lens uses a motor driven by ultrasonic waves to provide a quiet, high-speed AF.
