The Canon EF-S 10–22mm 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.[2] The field of view has a 35 mm equivalent focal length of 16–35mm, which is analogous to the EF 16–35mm 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.
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.[3]
Cost is the biggest criticism; until fairly recently, the 10–22 cost as much as many L-series lenses, but is only usable on APS-C cameras, and thus is questionable as a long-term investment.[4] [5] Others think this less of a concern.[3]
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.[3]
Optimal aperture (for sharpness and to reduce vignetting) is 5.6 to 8; 8 is particularly recommended at 22mm.[4] [5] [6]
Filters exacerbate vignetting, hence thin filters are recommended at 10mm, and stacking filters is discouraged.[3]
In May 2014, Canon announced a less expensive alternative wide-angle zoom for APS-C bodies, the EF-S 10–18mm. The new lens, which is being sold alongside the 10–22, is slower than the 10–22 (maximum aperture range of 4.5–5.6) and also lacks a USM motor, but adds both image stabilization and Canon's stepping motor technology. It is also smaller and lighter than the 10–22.[7]
Sigma offers two ultra-wide angle lenses for APS-C sensors—the 8–16 DC and 10–20 DC. Tamron also offers a 10–24mm ultra-wide zoom lens for APS-C cameras as well as an older 11–18mm lens.
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.[8]
