The super wide-angle capability of the Sigma 10-20mm zoom makes it a very powerful tool for both indoor and landscape photography. The Sigma 10-20 is designed with digital photography in mind, and is tailored to achieve outstanding results with cameras which have an APS-C sized or smaller image sensor. Aspherical lenses correct for distortion and aberration, which ensures top-quality images from edge-to-edge, across the entire zoom range. HSM equipped models make fast, quiet autofocus a reality, and the lens is capable of full-time manual focus as well. The Sigma 10-20mm has a minimum focusing distance of 24cm (9.4 inches) at all focal lengths, and is equipped with an integral Petal-type hood to block out extraneous light. More

One piece of glass mold and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration.

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.
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.
