slrgear‘s review Edit

The Canon 17-40mm f/4 L is a high quality lens with a full-frame image circle that showed really exceptional performance on the EOS-20D we used to test it with. All in all, the 17-40mm f/4 L easily justifies its premium price with top-notch optical performance.

ephotozine‘s review Edit

It's hard to write a succinct round-up for this lens, as it really depends on the kind of photography you do and the type of camera you are using as to whether I'd recommend this lens. For example, if you shoot subjects which require sharp details right into the corners and low distortion, such as some landscape work, or architecture, this lens may be quite frustrating for you. The reason I say frustrating, rather than unsuitable is because the lens handles well, is superbly built and shows excellent sharpness in the centre, and even towards the edges of the frame at 17mm. It's the sudden drop in quality in the far corners that is a little disturbing.

Camera Labs‘s review Edit

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.

photozone‘s review Edit

It's 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 has overstretched things a little with respect to the 17mm setting. The lens is able to deliver a very high resolution for most of the image field but the corner performance is poor thus spoiling the game here - this is like cappuccino without the cream for a ultra-wide lens where corner to corner sharpness is simply more critical than for a tele lens for instance.

The-Digital-Picture‘s review Edit

Because it is a very high quality but moderately-priced ultra wide angle zoom lens, the Canon EF 17-40mm f/4.0 L USM Lens is one of Canon's best selling lenses.The 17-40 f/4 L fills out the bottom focal length range of Canon's f/4 L zoom lens series. It is the lightest L lens currently made (1.1 lbs / 475g) and is the smallest L zoom lens currently produced (3.3" x 3.8" / 83.5mm x 96.8mm - DxL).
