The construction is weather-resistant to allow the lens to be used in a maximum number of settings.

Camera Labs - Canon EF 17-40mm with 5D review
by cameralabs.com UK Monday, January 01, 0001
Review :
The EF 17-40mm f/4.0L is one of the best lenses in Canon's range. It brings you a taste of the truly exotic with ultra-wide coverage, while boasting 'L' quality all at a surprisingly affordable price. Sure it ain't exactly cheap, but it's considerably more affordable than the EF 24-105mm f/4.0L and almost half the price of the EF 16-35mm f/2.8L. On the downside, our samples were quite soft in the corners when zoomed-into 40mm and focused at infinity, and the combination of full-frame digital with wide angle means you'll have to put up with quite significant light fall-off in the corners. There's also the annoying fact many EOS 5D owners wanting a practical two lens kit could end up with a gap between 40mm and 70mm. Find out more in our full review with test results - and for a demonstration of this lens in action, check out our video tour. Also see our full review of the EF 17-40mm with the 400D / Rebel XTi, where we've compared it against other general purpose Canon zoom lenses.
