Canon's EF-S 10-22mm USM is one of the best quality ultra-wide-angle lenses in its range. As an EF-S model, it will only work on cropped-bodies, but the equivalent range of 16-35mm is ideal for capturing expansive landscapes, cramped interiors, large buildings or big group shots. The USM focusing is also quick and quiet, and again the optical quality is excellent. If you own a cropped-body and want a quality ultra-wide zoom, this is the one for you.

Canon EF-S 10-22mm f/3.5-4.5 USM

Canon EF-S 10-22mm design and build quality

Pictured below are the four zooms in Canon’s current EF-S range: from left to right the EF-S 10-22mm, EF-S 17-55mm, EF-S 17-85mm and EF-S 18-55mm lenses, each zoomed-out to their widest focal lengths.

Measuring 84x90mm (diameter x length), the EF-S 10-22mm is roughly as wide as the EF-S 17-55mm and tall as the EF-S 17-85mm, but unlike the other lenses pictured here, doesn’t physically extend as you zoom-in. Like the Canon EF 17-40mm, an internal section shifts back and forth slightly as you adjust the zoom, but does so entirely within the limits of the outer barrel. This makes the EF-S 10-22mm appear much smaller than the EF-S 17-85 and EF-S 17-55mm lenses when all are zoomed-in – see below.

With the same external barrel width as the EF-S 17-55mm, it’s not surprising to find the EF-S 10-22mm sharing the same 77mm filter thread. This is significantly larger than the 67mm thread of the EF-S 75-85mm or the 58mm of the EF-S 18-55mm lenses.

A lens hood (EW-83E) and carrying pouch (LP1319) are available for the EF-S 10-22mm, but you’ll need to buy them as optional extras. While this is the same situation as other EF-S lenses, it still seems a little mean not to at least include the lens hood. Pouches and hoods come as standard only with Canon’s L lenses.

The biggest physical difference between the four EF-S zooms is weight. At 385g, the EF-S 10-22mm may still be twice as heavy as the almost feather-like EF-S 18-55mm kit lens, but is noticeably lighter than the 475g EF-S 17-85mm and the relative heft of the 645g EF-S 17-55mm, although to be fair the latter does boast a constant f2.8 aperture.

The exterior design and build quality of the EF-S 10-22mm is to all intents and purposes identical to the EF-S 17-85mm and EF-S 17-55mm models. All have similar-feeling focusing and zoom rings, and position them with the focusing ring closest to the body and the zoom ring furthest. While all three lenses are a big step-up from the kit EF-S 18-55mm lens, none are in the same physical league as Canon’s L lenses. The zoom and focusing rings on L lenses feel much smoother and the overall build quality more confident.

In terms of focusing, the EF-S 10-22mm employs one of Canon’s USM motors which is both fast and quiet. It’ll focus from its closest 24cm distance to infinity in about half a second, and thanks to internal focusing, the filter mount doesn’t rotate – a relief for anyone who uses polarising or graduated filters.
