Canon EF-S 10-22mm f/3.5-4.5 USM SLR Lens for EOS Digital SLRs

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 shot 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. Exceptionally light and compact for its focal length range the EF-S 10-22mm f/3. 5-4. 5 USM also has an incredibly close minimum focusing distance of just 24cm. A ring-type USM works in concert with the camera to provide super-fast precision auto focusing and predictive tracking - with full manual override available at any time. Designed specifically for digital photography the lens has specially shaped lens elements and Super Spectra coatings to suppress ghosting and flare which can be caused by reflections off digital camera sensors. An exclusive optional lens hood can further reduce the incidence of flare. A circular aperture provides a pleasing background blur when shooting with a wide aperture; ideal for creating a sense of depth and getting your subject or model to stand out from the background.

  • 10-22mm wide-angle zoom lens with f/3.5-4.5 maximum aperture for EOS digital SLR cameras

  • Superior AF performance and speed with full-time manual focus with the turn of a ring

  • Close focusing to 9.5 inches; fills the frame with subjects as small as 3.6 x 5.4 inches
