Relevant part:


"For the most part, I find the results to be very indicative of the image quality of the lens being tested and the comparisons work very well - the results are even better than I had hoped for. However, I'm not totally satisfied with theCanon EF-S 17-55mm f/2.8 IS USM Lens ("http://www.the-digital-picture.com/Reviews/Canon-EF-S-17-55mm-f-2.8-IS-USM-Lens-Review.aspx)results - the 17-55 under-performed in the comparison tool images in my opinion. And the cheapCanon EF-S 18-55mm f/3.5-5.6 IS USM Lens ("http://www.the-digital-picture.com/Reviews/Canon-EF-S-18-55mm-f-3.5-5.6-Lens-Review.aspx)performed better at the wider focal lengths at the relatively short distance than I would expect to see from this lens - it over-performed in the comparison tool."
