Cons: Variable aperture, doesn't include a lens hood.

Pros: Build quality, very sharp, excellent AF, tremendous range, IS works very well.

Summary: For a walkaround lens you have to make a trade... reach or speed. If you want a very fast lens, this isn't it. If you want a wide zoom range with excellent IQ, nothing could be better on an APS-C camera. This is both wider and longer than any alternative that can come close to the IQ... assuming you have enough light.

Cons: Expensive. My copy also had really bad asymmetrical vignetting. It was sharp, but the vignette made it unusable. I exchanged it for another copy which also had the problem. After this I gave up and moved on

Pros: Extremely sharp. Fast focusing. Amazing IS.

Summary: Sharp lens with a very useful range and great IS. Just make sure you get a good copy and check for decentering and asymmetrical vignette problems, quality control issues.

Cons: - I only took it out for 2 short trips, and found there are some dust get in... - The silver ring around the lens is just a paper sticker, can u believe it? - I think the lens I purchased should not pass the QC, because the right side of the image is obvious softer than the left side. Same problem like fotofan_1's. - Obvious CA that often cannot be removed by DPP or ALR - No lens hood included, like always - Expensive as a silver ring lens

Pros: - IS works very well. - very sharp in the center of the image

Summary: Need great luck to get a good lens of this model.

Cons: Significant decentering issues. Visibly and measurably (by filesize) less sharpness and contrast in right half of picture than cheap and good value kit lens EF-S 18-55 IS.

Pros: Great zoom range

Summary: Theoretically a great lens, but apparently pretty variable optical quality (given the high praise earned in many professional tests).
