The Canon EF-S 10-22mm f/3.5-4.5 USM is an
ultra wide-angle zoom lens with dynamic expressive capability for all EF-S
mount digital EOS cameras, exceptionally small and lightweight for maximum
mobility.
With an effective focal length range of
approximately 16-35mm in 35mm format, this 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, 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.
Note: Not suitable for 35mm film SLR
cameras, or for 35mm size "full-frame" digital cameras, e.g. 1Ds
or Kodak Pro SLR/c.
Note: Not suitable for 35mm film SLR
cameras or digital camera with image sensor bigger than APS-C size, only
fits on the EOS Digital Rebel series or 20D and 30D SLR cameras.
