Build and Handling
Being designated an L lens almost guarantees that the build quality of this lens will be good to excellent and you will not be disappointed in this area. The design incorporates the usual controls, a zoom ring marked at 17, 20, 24, 28, 35 and 40mm, a distance window with no attempt at a DOF scale, and a well torqued manual focus ring. There is an MF/AF switch to the left of the distance window, and that is about it. During manual focus, the ring requires about a third of a turn from one limit to the other but does not move during autofocus. Autofocus can be manually over-ridden without switching and the whole operation is silent and quick. The lens does not change length during either AF or zooming operations and the front element does not rotate, making the use of filters much simpler. The 77mm filter thread is also a popular size, which, although not small, does help to keep long term costs down. The lens is kept down to a reasonable size considering it was designed for 35mm cameras and can be used on them and full frame digital as well as cropped sensor cameras.
As mentioned in the opening paragraph, the lens is almost legendary and does produce fine results. But with the ever-increasing resolution of high-end sensors and Canon’s recently stated intention to produce more full frame sensors, can this lens keep up with the game. It is widely recognised as a lens with good contrast and control of distortions and the handling of chromatic aberrations is pretty good also, so more interest during the test procedure was placed on the pure resolving power of the lens. The answer is that, as things stand at present, it is fine. But, and we are talking the top end of the existing cameras here (1Ds MkII at 16.7mp), any more resolution and the lens will start to struggle. With lesser cameras there is not a problem and the lens will easily cope with such megapixel marvels as the newly announced 5D. The fact remains that some of the newer designs, especially those made purely for cropped sensors can out perform this lens from a resolution point of view.

This is an exceptionally good lens and deserves it reputation, finding its place in most camera bags of professionals using Canon gear. The slightly warm colours produced by Canon L glass and the good contrast and control of other elements required for a nice lens are all there. The results will not disappoint. With recent improvements in lens design however, at the very top end it is staring to look a little long in the tooth.
In summary, the main positive points of the Canon 17-40mm f/4 L USM lens are:
Consistent performance throughout the focal range.
Good value for money
Negative points are:
Top end cameras already at the limit of this lens’ resolution.
Edges drop off a bit as focal length increases.

May I hereby request your opinion re which camera would be more suitable for the above two purposes with this lens? I ask this question because there are reports that with the emergence of high end DSLRs (like 50D); this lens might have to be pushed to its limits. Please revert.
Thank you for your attention to this matter.

First, determine your budget, focal length, and aperture needs.
If you frequently find yourself zooming out to get everything in a frame, you will want a wide angle lens such as this. If you frequently find yourself zooming in, this is not the lens for you. On a full frame body such as Canon EOS 5D, this lens becomes ULTRA wide angle. On an APS-C crop body such as Digital Rebel XTi (which I used for this review), it becomes MEDIUM wide angle. But thanks to 1.6x crop factor, this lens expands to more usable 35mm equivalent focal length of 27 to 64mm.
Second, audition the lens if you can.
By definition, a walkaround lens should be relatively portable. At 1.1 lbs., Canon's EF 17-40mm f/4L USM is neither super light nor neck breakingly heavy. In fact, it weighs almost the same as Digital Rebel XTi -- really nice balance. The lens feels very solid with supreme build quality that only L-series lenses offer. Although this lens is weather proof and therefore sealed against liquid and dust, I strongly recommend getting a 77mm filter to protect the front lens element. With it, this lens is made to last.
