| Product Description The EF17-40mm f/4L USM is an ultra wide angle Canon EF zoom lens meant for professional and high amateur SLR EOS camera users.While it is an excellent lens when used with an analogue SLR camera, the EF17-40mm f/4L USM is especially well suited for digital SLR cameras with an imaging sensor size smaller than the 35mm format. Indeed on such digital SLR cameras these focal lengths can give an angle of view approximately equivalent to that of a 28-70mm lens used on a 35mm camera, which makes it the ideal standard zoom lens.The EF17-40mm f/4L USM has 12 lens elements arranged in 9 groups. Super Spectra Coating on the elements ensures excellent color balance and minimizes ghosting and flare. To provide superb image quality over a 17-40mm zoom range the lens uses three aspheric elements of two different types, while Super UD (Ultra-low Dispersion) glass is used to prevent the chromatic aberrations that often can degrade the subject edge clarity.Minimum focusing distance is just 28mm throughout the entire zo...

Top Reviews  A must-have for every Canon SLR ownerReview created: 09/22/05 by:  48 of 50 people found this review helpful. There are some lenses that you just HAVE to have in your lens kit ... this is one of them. Wide angle lenses are increasingly popular, particular with the 1.6x crop factor in the consumer-line of Canon SLRs (10D, 20D, Rebel, Rebel XT), and that has driven both the supply and demand for high-quality wide-angle lenses that are also affordable. At about $700 USD, this is a terrific starter lens for moving into L glass. The lens is fast and sharp, with little vignetting and chromatic aberration. It can be a little bit soft at f/4, but it's fantastic outdoors. The build quality is classic L. A natural comparison is to the Canon EF 16-35mm f/2.8 L, and the faster spec is nice. But it's widely accepted that this lens is the faster of the two, and considerably cheaper. Don't even bother comparing it against the Canon EF-S 18-55 f/3.5-5.6 USM. If you like wide angles, this one is a terrific choice -- I leave it on my camera all the time. I would only consider replacing this with the Canon EF 24-70mm f/2.8 L, but only if I move up to a full-frame sensor. Consider complementing this lens with the Canon EF 70-200mm f/4 L (also a good deal) and the Canon EF 50mm f/1.4. Review ID: 10000000000000759 Was this review helpful? Report this review WIDE WIDE WIDE Yeah~Review created: 07/06/06 by: 11 of 13 people found this review helpful. This is one of my favorite lens when it comes to shooting outdoor landscape, group shots, creative, out of ordinary shots. Our normal eyes see things at about the same as 50mm lens sees. 17mm gives really wide view and often you can create some dramatic shots with it. As a member of "L" lens, this lens uses better glass than non L lens thus it is able to produce sharper images and gives more punch color. Build quality is excellent and has water seal that works with high end professional cameras. At about $600~$700 street price, this is a great lens to keep. There's a similar lens though. Canon EF 16-35mm f/2.8L. It's little faster and has 1mm wider advantage, but has ticket price of almost twice as much as 17-40mm, and many people will agree that 17-40mm does well. A complementing lens would be EF 70-200mm f/4 L along with EF 50mm f/1.4 which I own both of these lens. Thanks for reading my review. Review ID: 10000000001323534 Was this review helpful? Report this review  wide angle only. not that good for everyday use6 of 7 people found this review helpful. Its good if you are sure you only want wide angle, but I would recommend that if you get this, you also get another with wide angle-telephoto zoom. This 40mm is a bit low for you to zoom in on many things. Review ID: 10000000002760959 Was this review helpful?

The lens were not scratched and lens were in decent shape. The exterior printing was worn more than I expected. The lens preform as they are suppose too but overall I feel that product has more wear than advertised. I had received a discount of 10% through e-bay and that more than equaled out the problem.
