What's this? This is based almost entirely on the lens¿s image quality, based on tests of sharpness (modulation transfer function), geometric distortion, reflexes within the lens (flare), veiling glare index, vignetting, and macro performance. Ease of use was also considered.
The Canon EF-S 17-55mm f/2.8 IS USM is part of the interchangeable & SLR lens
test program at Consumer Reports. In our lab tests, interchangeable & SLR lenses
models like the EF-S 17-55mm f/2.8 IS USM are rated on multiple criteria, such as those listed below.
Image quality:
Image quality is based on tests of sharpness (modulation transfer function), geometric distortion, reflexes within the lens (flare), veiling glare index, vignetting, and macro performance.
Image stabilization:
An image stabilizer compensates for handheld camera shake. Optical (in the lens) and mechanical (in the camera body) image stabilizers are the best types to use, although some cameras include simulated stabilization, which is considered a less effective type than the others.
Modulation transfer function:
This is a measure of lens performance and shows how well a lens reproduces object detail in the image it produces.
About This Brand
One of the largest camera and lens manufacturers in the world, Canon currently sells scores of lenses in a wide variety of focal lengths. Canon splits its lenses into two main classes—its standard EF (electro focus) series, and its consumer-level EF-S lenses, which are only compatible with its smaller, APS-C sensor bodies. There are also two smaller classes of Tilt-Shift (TSE) lenses and Macro (MP-E) lenses. More generally speaking, Canon splits its lenses into nine main categories: ultra-wide zoom; standard zoom, telephoto zoom, wide angle, standard and medium telephoto, telephoto, super telephoto, macro, and tilt-shift.

Zoom ratio The zoom ratio is expressed by a value such as 2x or 3x, and describes the relationship between the longest and shortest focal lengths. For example, a 3x optical zoom with a minimum focal length of 18mm would have a maximum focal length of 54mm.

I bought this lens with trepidation since the chatter on review sites is more negative than the expected background grousing. The glass is superior no doubt (initially I got superior results) but it is packaged so poorly with such sloppy fit and finish that it does not hold up. After a year of light use (that included shooting a 4th of July parade in 100 plus temperature) my lens is a basket case for pincushion and focus. I am back to using the original kit lens.
How long have you owned it:

No, I would not recommend this to a friend.

Speed and focus accuracy, image quality, sharpness, moderately priced
Weakness
55mm is a little short but for about 80% of the shots that I want to take it is long enough
First, I would rather have something more like a 20-135. Beyond that this lens is the best that I have tried out of the 17-85 F4 and the 28-135 F3.6. I think the F2.8 is almost required to get decent focus accuracy and reliability. It may not need to be a *constant* F2.8 but at least at the wide angle it should be F2.8. The short porch is very nice, makes it easy to shoot whatever you are standing in front of, the 28-135 is just too long for this. The only thing this 17-55 leaves me wanting is another 2x or so of zoom range. It would be great at 20-100, even. Wide-angle at night only works for close-up subjects, and the 55mm limit means a lot of walking around to get a good crop on the shot. And you can't use digital zoom if you don't get a good focus, so with the Rebel XTi and just about every lens that I've tried, I can't rely on getting a good focus at high zoom. Sometimes it works, sometimes not. But otherwise, I think this lens is worth the $900, the 17-85 is worth the $400, I'd stay away from the 28-135 and the kit lens is not all that bad for free. What I really want, now, and I guess I'm going to have to wait for, is a good-quality 20-120 or so, F2.8-F4.5ish lens with IS. There is no point in getting a lens that will not focus reliably. Now as far as speed...I've shot this camera handheld at night at full zoom and gotten good shots, plenty of times. Pick your poison: ISO1600 RAW to ISO400 jpeg, it'll do it for you.
I love the constant aperture and IS. It's awesome for indoor handheld shooting. I wasn't used to such a wide aperture so it's easy to overdo the shallow DOF and have part of you subjects face (eg ears) out of focus when that wasn't your intention. It also takes great landscape and night photos. However, as expected for very wide angle lens there is some vignetting at the wide end but not usually a problem. However, becomes a major problem when using the lens hood between about 17-20mm against a bright uniform background (eg blue sky). it also seemed like the polarizing filter might have made it more obvious (?). Anyways, not a deal breaker of course but just something to be aware of. Others on the web have reported problems with dust. I have not had any dust problems after a month or so and I don't do anything special to prevent it. Overall a great lens. Blows the 18-55mm kit lens away.
price, size (it's pretty bulky), EF-S mount only, no hood
This is one of the best EF-S lenses available on the market at this time. Lens is pretty sharp throughout, although it vignettes somewhat at 17mm. The price is a killer - $1000 for a non-L lens is just expensive. Build quality is average as well - it's not bad, but can't be compared to L lenses. I often use this lens as a general walk-around lens, although it is a bit too bulky for my taste. There are a couple of comprehensive reviews available on the web, so if you're considering buying one, check them out and compare to some other EF-S lenses. One site that comes to mind is www.slrlensreview.com - has a handson review,
