The EF-S 10-22mm f/3.5-4.5 USM Lens from Canon is an ultra wide-angle zoom lens with dynamic expressive capability and a lightweight build for all EF-S mount digital EOS cameras. With its effective focal length range of approximately 16-35mm in 35mm format, the EF-S 10-22mm f/3.5-4.5 USM is a remarkable lens with outstanding image quality that will take your photography into new dimensions and areas of dramatic expression.
The super-wide zoom not only gives you the freedom to get exactly what you want in the capture, it dramatically alters perspective to allow for dynamic expression. The lens allows you to get extremely close to subjects, exaggerating the difference in size between a near object and its background. Creative photographers can use this phenomenon to create excellent separation between subject and background for a strong sense of presence, or for a pan-focus effect with everything from foreground to background sharply in focus.
Designed specifically for digital photography with APS-C size sensors, the lens has three a spherical and one Ultra-low Dispersion elements to minimize aberrations and Super Spectra coatings to suppress ghosting and flare, which can be caused by reflections off digital camera sensors. An optional lens hood can further reduce the incidence of flare.
