In typical cheapskate fashion, at least when it comes to lens hoods, Canon doesn't supply one with this lens, which when added takes the overall price to about £500.

The Canon EF-S 10-22/3.5-4.5 is a very good lens. There is a little corner softness wide open at 10mm, but overall the image quality is excellent. Those who claim that this lens shows "L" quality performance may not be wrong.

Canon's 10-22mm is a 2.2x zoom, offering potential great value for money. The Canon EF-S 10-22mm f/3.5-4.5 USM lens review sees just how good it is in the real world...

Extended zoom range

Lack of MTF consistency

First released in August of 2004, Canon EF-S 10-22mm f/3.5-4.5 USM has an equivalent field of view of 16-35mm on APS-C type cameras with 1.6x crop ratio. The lens bears EF-S designation, meaning that it is specifically designed for APS-C type dSLRs (the lens has a protruding rear element, which...

Up until now, there haven't been many truly wide angle zoom solutions for Canon's APS- C sized sensors. This lens changes that picture, but at a price. But if you need a high-quality wide to medium-wide zoom for your small sensor format Canon, you can't beat the performance of the EF-S 10-22mm USM.

With framing equivalent to a 16-35mm zoom on a full frame body, the Canon EF-S 10-22mm f/3.5-4.5 USM Lens provides EF-S compatible camera body owners with the ultra-wide angle focal lengths so often missed on this small-sensor format camera. EF-S is Canon's moniker for Small Image Circle.

The Canon EF-S 10-22mm f/3.5-4.5 USM (16-35mm equivalent in 35mm parlance) was designed to cover the APS-C format, specifically the EOS 20D and both EOS Digital Rebels (plus future APS-C models). Canon's EF-S lenses (S = Short Back Focus) are physically matched to these cameras.

The Canon EF-S 10-22mm f/3.5-4.5 offers a wide-angle zoom option for both EF and EF-S fit cameras. Boasting an Ultra-Sonic Motor and full manual focus control, does it compare well against established 3rd party options?

Excellent resolution in the centre at most apertures and focal lengths; Light weight; Good build quality

May be prone to flare and no lens hood is supplied; Falloff in resolution towards the edges at 22mm

The superb distortion control means this can be a rewarding lens to use. However the sharpness has been a major disappointment for me. UWA lenses often have the foreground to the edge of the image where the lens is weakest, but even centre resolution isn't on a par with the price bracket.

Rectilinear with excellent distortion control, even at 10mm; Light and compact; Decent but not exceptional build quality; DPP lens profile completely eliminates

Price (though it has dropped below ￡500 recently so its less of an issue now); Not particularly sharp, even in the centre; More chromatic abberation than I expected at the price

The EF-S 10-22mm f/3.5-4.5 USM from Canon has a 35mm equivalent focal range of 16-35mm, offering a very wide, corrected field-of-view. The lens is relatively compact in design, with a zoom ring at the front and a small manual focus ring at the rear.
