Canon EF-S 17-85mm f4~5.6 IS USM lens review Gordon Laing, December 2005

Outdoor / Resolution / Corner sharpness / Fringe and macro / Geometry / Vignetting

Canon 17-85mm vs 18-55mm vs 17-40mm outdoor scene, with EOS 350D / XT

Canon EOS 350D with 17-85mm lens at 33mm f8   To compare real-life performance we shot the same scene with each lens within a few moments of each other using a Canon EOS-350D / Rebel XT set to its best quality JPEG settings. All lenses here were set to f8 using Aperture Priority mode. The crops are taken from the originals and presented here at 100%.

The image left was taken with the Canon EOS-350D using the 17-85mm EF-S at 33mm f8; the original JPEG measured 2.82MB. In terms of actual resolution, there's little difference between the crops, although the 17-40L has recorded a wider range of tonal detail than the EF-S lenses.
