The 10-20mm F3.5 EX DC HSM lens gives photographers more 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 emphasise, for example, expanses of a landscape.

The large, constant aperture of F3.5 provides a bright image in the viewfinder for the photographer to be able to easily check focusing and composition.

One SLD (Special Low Dispersion) and two ELD (Extraordinary Low Dispersion) glass elements are employed for effective compensation of colour aberration. The use of two glass mold and two hybrid aspherical lenses offer excellent correction for distortion and astigmatism and ensure superior image quality. The Super Multi-Layer coating lowers any flare and ghosting and provides high contrast images throughout the entire zoom range.

This lens incorporates HSM (Hyper Sonic Motor), which makes sure of a quiet and high-speed auto focus as well as full-time manual focus override by rotatingthe focus ring.

An inner focusing system eliminates front lens rotation, making the lens equally suitable for using the included petal-type lens hood which blocks out extraneous light.

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 emphasises perspective and allows the photographer to capture high quality images, not only of the foreground subject but also the background scenery.
