Canon EF-S 10-22mm f/3.5-4.5 USM SLR Lens

Many beginning and intermediate level photographers struggle with capturing great wide-angle landscape images. All too often they try to capture a wide vista using an 18-55 mm kit lens, usually with less than perfect results. Canon has come to the rescue with a new EF-S 10-22mm f/3.5-4.5 USM wide angle zoom lens for their EOS 20D and Digital Rebel digital SLR models. This is without a doubt one of the most amazing lenses on the market today. Have you ever tried to take a picture of some landmark only to find that by the time you're far enough away to squeeze the entire image into the viewfinder everything is so small you can't make out any details whatsoever?  Well, this unbelievable lens allows you to take tac-sharp photos of buildings and other large landscape objects while standing within just a few feet of them! With this one purchase you can raise the quality of your landscape and architectural photography by several levels! Here are a few of its impressive specs: Fantastic optical quality True wide-angle coverage with select Canon Digital SLR cameras Outstanding AF performance and speed Always available manual focus by simply turning the focus ring Close-focusing to 9.5 inches Relatively small size and light weight for an ultra-wide zoom lens Inner focusing system - the length doesn't change when zooming Circular aperture design produces natural highlights, even stopped down 2 stops Electronic diaphragm - manually-set apertures stay constant from f/4.5 thru f/22 EF-S lens mount for EOS 20D and Digital Rebel camera bodies Primary advantage of the Canon EF-S 10-22mm f/3.5-4.5 USM SLR Lens: Its stunning image quality and super wide-angle coverage are among the best of any wide-angle zoom on the market. Primary disadvantage: A bit pricey compared to 3rd party zoom lenses of comparable quality. Recommendation: If you shoot lots of landscape and architectural images with a Canon digital SLR that works with it, you simply cannot buy a better wide-angle zoom lens in the same price range.
