The Canon EF 17-40mm f/4 USM L is one of the most popular L class lenses thanks to its relatively affordable price and its dual purpose scope - it can serve as a standard zoom lens on APS-C DSLRs and its an ultra-wide zoom lens with an attractive ran...
Bottom line Its not exactly easy to design a flawless full format lens and the Canon EF 17-40mm f/4 USM L shows its part of the struggles here. The lens is not overly fast but it has a comparatively broad range for a lens in this class and it seems as if Canon h...

Canon makes two high-quality wide-angle zoom lenses for full-frame cameras, the 17-40/4L reviewed here and the Canon EF 16-35mm f/2.8L USM, $1249 (review). In the digital era, the 17-40 has been overlooked to some extent. It isnt wide enough to be dra...
Bottom line It isnt lighter than the 16-35/2.8L. It isnt better quality than the 16-35/2.8L. It isnt dramatically wide on the small sensor cameras. However, if you want a high quality wide-angle zoom with a medium weight and a medium aperture, the 17-40/4L is a...

Bottom line Canon EF 17-40mm verdict for cropped APS-C bodies The Canon EF 17-40mm may deliver spectacular ultra-wide angle coverage when fitted to a full-frame body like the EOS 5D, but offers a more normal, general-purpose range when mounted on cropped bodies l...

Canon is the only company to make digital cameras with 35mm sized sensors. This lens can still be used on the APS-C sensor-equipped cameras, such as the EOS 400D or 30D, but there is a shift in the angle of view – expressed as a 35mm eq...
