Canon EF 17-40mm f/4L USM Ultra Wide Angle Zoom Lens for Canon SLR Cameras Reviews
| 573 of 582 people found the following review helpful:  My walkaround lens, By This review is from: Canon EF 17-40mm f/4L USM Ultra Wide Angle Zoom Lens for Canon SLR Cameras (Camera) The walkaround lens. This very topic leads to a heated discussion among DSLR photographers.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...

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. The good: 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...

At least for me. I want my lenses to be a reasonable size (rules out the superb 70-200 f2.8 IS L), acceptably fast (at least f 4.0), preferably black (so that they are inconspicuous), not outrageously priced (admittedly this last factor being entirely subjective), and preferably a zoom for the additional flexibility.Primes are absolutely fantastic values, reasonably priced, fast, and inconspicuous, BUT offer limited flexibility which, in my mind overrides the other factors. I purchased this lens for the wider end of my shooting needs and I couldn't be more pleased. It takes beautiful pictures, sharp, beautifully saturated, with no discernable vignetting and little flare under normal circumstances. This lens has beautiful bokeh IMO and is every bit the equal, again IMO, of the 16-35 f2.8 L in every respect other than speed (f 2.8 vs f 4.0). With the new... Read more |
