Summary

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 purple fringe and macro comparison

We tested each lens at its widest and longest focal lengths with the aperture wide open using a Canon EOS-400D in Aperture Priority mode. The crops are taken from the upper left corner of the chart and presented here at 100%.To measure and compare the Canon 10-22mm’s purple fringing caused by lens chromatic aberrations and sensor blooming, we photographed a test chart with areas of very high contrast using it and a number of rival lenses.

The Canon EF-S 10-22mm exhibits a little purple fringing at its widest position in line with the others. Fringing is virtually absent at the long end, again in line with the other three.

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

Canon 10-22mm EF-S macro test
10-22mm EF-S at 22mm f8 (35mm equiv)
Max area of 124x82mm

The dark lines are 10mm apart and the result is not cropped. Smaller areas are preferred in this test.To measure and compare the Canon 10-22mm’s macro performance we photographed a chart using it and a number of rival lenses at a focal length and distance which delivered the maximum possible reproduction.

The image above was taken with the Canon EF-S 10-22mm zoomed-into 22mm f8. With the lens positioned at its closest focusing distance, it delivered an area measuring 124x82mm, coincidentally identical to our measurement taken with the EF-S 17-55mm. Geometric distortion, as detailed on the next page, is respectably low, but the relatively large area won’t get any macro enthusiasts excited. To be fair though, the EF-S 10-22mm isn’t designed to produce large reproductions. It is possible though to get pretty close to a subject while maintaining a large depth of field, as illustrated in our Gallery. The macro result here is also significantly better than the 166x110mm area captured by the EF 17-40mm on a full-frame Canon EOS 5D.
