The Canon EF-S 10-22mm f/3.5-4.5 USM lens is a wide to ultra-wide angle zoom lens for Canon digital single-lens reflex cameras with a Canon EF-S lens mount.1 The field of view has a 35 mm equivalent focal length of 16-35mm, and it is analogous to the EF 16-35mm f/2.8L on a full-frame camera. It is an internal focusing lens. Of the 13 elements, one is of Canon's Super Ultra-Low Dispersion glass and 3 are aspherical elements.

Reception
Praise
The 10-22 is widely considered to have very good image quality (sharp and low distortion) and build. The optical construction is similar to L-series lenses, but it is not designated as L-series (as reflected in the build quality), which some have argued is for marketing reasons, as with the 17-55.2
- "This is an extremely sharp lens, at all three tested focal lengths."3
- "The Canon 10-22mm has much less distortion than any wide zoom I've tested"4
- "There is moderate barrel distortion at 10mm, a negligible amount at 15mm, and only a tiny amount of pincushion distortion at 22mm. Overall, exemplary performance in this measure."3
- "This lens is small, light and solidly built. Sometimes Canon's non-L series lenses can feel a bit cheap, but not this one. … there is little to fault about it with regard to either fit or finish."3
Criticism
Cost is the biggest criticism; the 10-22 costs as much as many L-series lenses, but is only usable on EF-S cameras, and thus is questionable as a long-term investment.35 Others think this less of a concern.2
Chromatic aberration is somewhat high at 10mm, and vignetting is measurable at 10mm and maximum aperture (0.85 EV units),6 but not terribly noticeable in normal use.2
Use
Optimal aperture (for sharpness and to reduce vignetting) is f/5.6 to f/8; f/8 is particularly recommended at 22mm.365
Filters exacerbate vignetting, hence thin filters are recommended at 10mm, and stacking filters is discouraged.2
Similar lenses
The Nikon 12-24 DX is Nikon's ultra-wide angle zoom, and is earlier, but is more expensive, not as wide, and has more barrel distortion.7
The Sigma 10-20 DC is the Sigma ultra-wide angle lens for APS-C sensors. Tamron also offers a 11-18mm ultra wide-angle zoom lens for APS-C cameras.
Some consider the Tokina 12-24 to be comparable and cheaper,8 while others consider the Canon 10-22 to be significantly superior.4 In May 2008, photozone considered the Tokina 11-16mm, f/2.8, introduced in 2008, to be the best ultra-wide angle lens available for Canon APS-C Format cameras.9
