Canon EF-S 10-22mm f/3.5-4.5 USM uniformity comparison (shortest focal length)

10-22mm EF-S at 10mm f3.5 (16mm equiv)
Mean corner fall-off: 42.3%

 

To measure and compare the Canon 10-22mm's vignetting and light fall-off we photographed a white target with a highly diffused custom filter using it and a number of rival lenses.

The lenses were tested at their widest focal lengths with the aperture wide open using a Canon EOS-400D in Aperture Priority mode.

The images were analysed with Imatest and the full areas presented here at a reduced resolution. Bigger percentages are better.




The image above was taken with the Canon EF-S 10-22mm lens at 10mm f3.5. Here the light falls off in the corners to an average of 42.3% of the center measurement, which while noticeably worse than the kit and EF-S 17-85mm lenses, is not unexpected for such an extreme wide angle lens. Indeed it's worth comparing how a lens with similar wide angle coverage performs on a full frame body: in our EF 17-40mm review using a Canon EOS 5D, the light fell off in the corners to 34.3% of the center measurement. It's also worth pointing out that while the corner light fall-off value of the EF-S 10-22mm is similar to the EF-S 17-55mm, the latter suffers from a much steeper and more noticeable gradient in the far corners, whereas the former is more gentle and less obvious. So not a bad result for the EF-S 10-22mm here considering its extreme coverage.

Canon EF-S 10-22mm f/3.5-4.5 USM uniformity comparison (longest focal length)

10-22mm EF-S at 22mm f4.5 (35mm equiv)
Mean corner fall-off: 55.3%

 

To measure and compare the Canon 10-22mm's vignetting and light fall-off we photographed a white target with a highly diffused custom filter using it and a number of rival lenses.

The lenses were tested at their longest focal lengths with the aperture wide open using a Canon EOS-400D in Aperture Priority mode.

The images were analysed with Imatest and the full areas presented here at a reduced resolution. Bigger percentages are better.




The image above was taken with the Canon EF-S 10-22mm lens at 22mm f4.5. Here the light falls off in the corners to an average of 55.3% of the center measurement, which again is worse then the kit and EF-S 17-85mm lenses, but not too far behind the EF-S 17-55mm. Once again the gradient is quite gentle and not particularly noticeable in real-life. Interestingly the light fall-off measured for the EF 17-40mm on the full-frame Canon EOS 5D is better than the EF-S 10-22mm when both are zoomed-in. At 40mm it measured a fairly respectable 63.1%.
