Digital Camera Lens
10-20mm f/4-5.6 EX DC HSM

The super wide-angle capability of the 10-20mm zoom makes it a very powerful tool for both indoor and landscape photography. It is specifically designed to optimise results with digital SLR cameras encorporating APS-C size image sensors or smaller. 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.
