Canon EF-S 10-22mm vs EF-S 18-55mm outdoor scene,
with EOS 400D
To compare real-life performance
we shot the same scene with the EF-S 10-22mm and EF-S 18-55mm lenses within moments of each other using
a Canon EOS-400D. Both lenses were tested here at 22mm f8, (equivalent to 35mm).
The 400D was set to Large Fine JPEG mode and the Standard Picture Style. The
crops are taken from the originals and presented here at 100%.
The image left was taken with the Canon EOS-400D using the EF-S 10-22mm at 22mm
f8; the original JPEG measured 4.2MB.
With both lenses set to 22mm f8 and focused at infinity, they deliver essentially the same degree of real-life detail in the middle of their fields, as illustrated in the centre crops. Note our resolution test on the next page though shows the EF-S 10-22mm slightly out-performing the kit lens in a studio environment.
The EF-S 10-22mm is clearly softer than the EF-S 18-55mm in the upper left corner as seen in the first row of crops, although roughly the same as the kit lens in the lower right corner as seen in the third row of crops.
It's also interesting to compare the EF-S 10-22mm on the EOS 400D against the EF 17-40mm on a full-frame EOS 5D. In the results from our EF 17-40mm review, the lens performed very well when zoomed-out to wide angle, but once zoomed-into 40mm, our sample was very soft in the corners. So while the EF-S 10-22mm is a little softer than the EF-S 18-55mm in the corners, it's not as bad as we experienced with the EF 17-40mm on a full-frame body. See our Gallery for more samples taken with the EF-S 10-22mm.
