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. ReceptionPraiseThe 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.[2]
CriticismCost 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.[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]UseOptimal aperture (for sharpness and to reduce vignetting) is {{f/}}5.6 to {{f/}}8; {{f/}}8 is particularly recommended at 22mm.[3][5][6] Filters exacerbate vignetting, hence thin filters are recommended at 10mm, and stacking filters is discouraged.[2] Similar lensesIn 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 {{f/}}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] The Nikon 12–24 DX is Nikon's ultra-wide angle zoom for its APS-C sensors (which are slightly larger than those of Canon), and is earlier, but is more expensive, not as wide, and has more barrel distortion.[8] 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. Some consider the Tokina 12–24 to be comparable and cheaper,[9] 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.[10] Noted photography blogger Ken Rockwell, however, considered the Canon 10–22 to be better than either version of the Tokina 11–16 — the original reviewed by PhotoZone,[11] or the Mark II released in 2012[12] — for Canon shooters. After reviewing the 10–18 in June 2014, Rockwell considers the 10–18 optically superior to all other ultrawides designed for Canon APS-C bodies.[13] References1. ^{{cite web |url = http://www.canon.com/camera-museum/camera/lens/ef/data/ef-s/ef_s10~22_35~45_usm.html |title = EF-S 10-22mm f/3.5-4.5 USM |work = Canon Camera Museum |author = Canon Inc. |accessdate = 31 May 2007 |archive-url = https://web.archive.org/web/20090611154221/http://www.canon.com/camera-museum/camera/lens/ef/data/ef-s/ef_s10~22_35~45_usm.html# |archive-date = 11 June 2009 |dead-url = yes |df = dmy-all}} 2. ^1 2 3 {{cite web |url = http://photo.net/equipment/canon/efs_10-22/ |title = Canon EF-S 10-22/3.5-4.5 USM Lens Review |last = Atkins |first = Bob |accessdate = 9 March 2008 |work = photo.net |archive-url = https://web.archive.org/web/20090721093117/http://photo.net/equipment/canon/efs_10-22/# |archive-date = 21 July 2009 |dead-url = yes |df = dmy-all}} 3. ^1 2 3 4 {{cite web|url=http://www.luminous-landscape.com/reviews/lenses/Canon-10-22mm-test.shtml|title=Canon EF-S 10–22mm f/3.5–4.5 USM|accessdate=9 March 2008|work=The Luminous Landscape}} 4. ^1 {{cite web|url=http://www.kenrockwell.com/canon/1022.htm|title=Canon 10–22mm|accessdate=9 March 2008|last=Rockwell|first=Ken|work=KenRockwell.com}} 5. ^1 {{cite web|url=http://www.photodo.com/topic_47.html|title=Canon EF-S 10–22mm f/3.5–4.5 USM|last=Andrews|first=Ian|work=photodo}} 6. ^1 {{cite web|url=http://www.slrgear.com/reviews/showproduct.php/product/135/cat/11|title=Canon EF-S 10–22mm f/3.5–4.5 USM|accessdate=9 March 2008|work=SLRgear.com}} 7. ^{{cite press release|url=http://www.usa.canon.com/cusa/about_canon?pageKeyCode=pressreldetail&docId=0901e02480beda0d |title=Canon Broadens Its Imaging Lineup with Two New EF Ultra Wide-Angle Zoom Lenses and White EOS Rebel SL1 Digital SLR Camera |publisher=Canon U.S.A., Inc. |date=13 May 2014 |accessdate=13 May 2014}} 8. ^{{cite web|url=http://www.kenrockwell.com/nikon/1224.htm|title=Nikon 12–24mm f/4|accessdate=9 March 2008|last=Rockwell|first=Ken|work=KenRockwell.com}} 9. ^{{cite web|url=http://www.photozone.de/Reviews/Canon%20EOS%20Lens%20Tests/45-canon-eos-aps-c/174-canon-ef-s-10-22mm-f35-45-usm-test-report--review|title=Canon EF-S 10–22mm f/3.5–4.5 USM – Test Report / Review|accessdate=9 March 2008|work=photozone.de}} 10. ^{{cite web|url=http://www.photozone.de/Reviews/Canon%20EOS%20Lens%20Tests/379-tokina_1116_28_canon?start=2|title=Tokina AF 11–16mm f/2.8 AT-X Pro DX (Canon) – Review / Lens Test Report|accessdate=15 July 2008|work=photozone}} 11. ^{{cite web|url=http://www.kenrockwell.com/tokina/11-16mm.htm#rex |title=Tokina 11–16mm: Recommendations |first=Ken |last=Rockwell |publisher=KenRockwell.com |date=September 2012 |accessdate=15 March 2013 |quote=If you shoot Canon, get the Canon 10–22mm, since it doesn't cost much more and has a much wider and longer zoom range.
