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, 30D, 40D, 50D, 60D,
and 7D SLR cameras.
