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.

[edit] Reception
[edit] 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]
[edit] 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.[3][5] 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]
[edit] Use
Optimal aperture (for sharpness and to reduce vignetting) is f/5.6 to f/8; f/8 is particularly recommended at 22mm.[3][6][5]
Filters exacerbate vignetting, hence thin filters are recommended at 10mm, and stacking filters is discouraged.[2]
[edit] 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.
Some consider the Tokina 12-24 to be comparable and cheaper,[8] while others consider the Canon 10-22 to be significantly superior.[4]
