Canon EF-S 10–22mm lens instance of lens model
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.
The field of view has a 35 mm equivalent focal length of 16–35mm, which is analogous to the EF 16–35mm f/2.8L on a full-frame camera. The 10–22mm is an internal focusing lens. Of the 13 elements, one is of Canon's Super Ultra-Low Dispersion glass and three are aspherical elements.Reception
Praise
The 10–22 is considered to have 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.
"This is an extremely sharp lens, at all three tested focal lengths.""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."
"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."
