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 corner sharpness comparison

To measure and compare the Canon 10-22mm’s corner sharpness we photographed the Enhanced Digital Camera Resolution Chart with it and a number of lenses using a Canon EOS-400D. The 400D was set to Large Fine JPEG mode and its Standard Picture Style.

Each lens was tested at its widest and longest focal lengths and with various apertures using Aperture Priority mode. The crops are taken from the lower left corner of the chart and presented here at 100%. No crops have been resized.

Zoomed-out to 10mm with its aperture wide open, the EF-S 10-22mm lens suffers from softness in the extreme corners, but it’s greatly improved as the aperture’s closed. It’s interestingly quite similar to the EF-S 18-55mm in this particular test, although the premium EF-S 17-55mm continues to deliver the best result, impressively even when its aperture is wide open at f2.8.

Zoomed-into 22mm, the EF-S 10-22mm delivers good results here throughout its aperture range which are roughly equivalent to the EF-S 17-85mm and EF-S 17-55mm when all are zoomed-in. Of course when the EF-S 10-22mm is zoomed-in, the focal length is closer to the other lenses zoomed-out. Therefore it’s well worth comparing the second set of results from the EF-S 10-22mm with the first set of results from the other three. Clearly the EF-S 10-22mm performs well in this regard, especially compared against the EF-S 17-85mm and EF-S 18-55mm models at similar focal lengths.
