8 out of 10 points and recommendedVery good constructionA little too big. Picture quality not fantastic.
I also own the Tamron 17-50mm F2.8 DI XR (Japan version) and find the Tamron produces better pictures than the Canon 17-40mL. Other reviewers at this site seem to concur.reviewed June 17th, 2007
9 out of 10 points and recommendedVery light and compact. Great pictures. Close to my Canon prime.Construction quality reflects very good pricing.
Buy this lens over the Canon 17-40mm L for its great value. Some (v. little) color bias when compared to the Canon. But fast lens makes it great for indoors and the filters are sure cheaper than the ones for the Canon 17-40mm L.reviewed June 17th, 2007 (purchased for $450)
