About half the price of the 16-35 f/2.8 lens, this L-series lens has an entirely new optical design with three Aspherical elements and a Super UD-glass element. The combination provides superb contrast and sharpness, even at the widest settings. It's ideal for both film and digital SLRs, and features the same weather-resistant design, rear gel filter holder, and high-speed Ultrasonic Motor as the EF 16-35mm lens.

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.
In terms of looks and feel, it doesn't get much better. Its rubberized full-time inner focus manual ring USM focuses smoothly, quietly, and quickly. Since it's inner focus, the lens will not extend beyond its metal casing whether you zoom in or out. The focus window shows focusing distance from 0.28 meter (0.92 feet) to infinity. The focal length marker indicates 17, 20, 24, 28, 35, and 40mm. The lens exudes quality from tip to tip.
You may tolerate heavier lens or may not mind lesser build quality of cheaper lenses.Read more ›
The 17-40mm f/4 is one of Canon's best deals in L-series glass. You have to spend twice as much to get a lens of similar quality, but just one stop faster. Does this make the more-expensive EF 16-35 f/2.8L a ripoff? Not for its own specific use: the extra stop gives you the speed to shoot in more indoor situations. Not all photographers need this. When indoors, we're often taking pictures of people, which are better suited to lengths around 50-100mm. To capture sweeping panoramas of parlors for Architectural Digest (or Coldwell Banker) the f/2.8 is the better lens and worth the step up in price, though in many cases you could use the f/4 lens with a tripod. All this means is that the f/2.8 is priced for professional specialists whereas the f/4 is for more general use. My bigger point is that Canon has its whole lineup positioned: the differences across lenses are specific and appropriately priced, which is good news for the consumer. It's hard to make a mistake buying homegrown Canon lenses, especially L-series lenses. You just have to figure out which set of two or three suits your range of uses.
The 17-40mm is a steal for people who need a walkaround lens for travel and outdoor photography. The shorter focal lengths of the zoom are great on a digital body, with nice reach and minimal distortion; just an ability to grab up landscape and wide situations end-to-end, even when standing close. The focal lengths around 40mm are tight enough for portraits and other local detail.Read more ›
This review is written from the viewpoint of someone whom has used many L-class lenses, and as such will be a little harder on this piece of glass. If you've never used a Canon L lens and you purchase this one, I guarantee you'll be quite pleased with your purchase. But this review is really meant for those who own other L glass pieces and are looking into adding this one to their collection.
L glass tends to mean some heavy-weight glass, however this lens is surprisingly light and small. In fact, it is the smallest/lightest L zoom Canon makes. You find yourself more likely to take it to places where there may not be much of a projected photo opportunity or where there is a higher risk in damaged gear due to its unobtrusive size. It really is one of those few L lenses that you can casually walk around with and not garner much for attention.
As with all L-glass, this ones very solidly constructed. It has a simplicity of design that minimizes risk to moving parts from shock. It is well-balanced and just feels like a tight glass package.
The lens performs very well in color and contrast. Natural saturation is excellent, easily on par with the L expectation. The color and saturation of this lens sits somewhere between the 70-200mm f/2.8 IS and the 24-70mm f/2.8.
I initially thought that the zoom range would be constraining (a mere 23mm of range?), but in reality the lens is fairly versatile. This especially true on a 1.6 FOVCF body (20D, 30D, 350D, 400D, etc), where the range is more like that of a normal zoom, at the cost of the super-wide advantage. The lens handles pretty much all composition tasks except those of a telephoto or 1.0x macro.Read more ›
