Review summary from DPReview
This isn't a lens for pixel-peepers who above all else demand critical corner-to-corner sharpness in every shot. But for more normal users looking for a versatile, all-in-one travel lens within a budget, and who'd prefer to while away their evenings looking at and sharing their images rather than post-processing them, it fits the bill just fine.
Scoring is relative only to the other products in the same category.

Sample images for Sigma 18-200mm F3.5-6.3 DC OS HSM
11.1x high zoom ratio lens with a built-in AF motor allowing auto focus with all Nikon APS-C DSLR cameras.
The Sigma 18-200mm high-zoom-ratio lens is designed exclusively for Canon digital SLR cameras and is capable of covering a wide range of focal lengths, from wide-angle to telephoto. Two Special Low Dispersion (SLD) glass elements and two hybrid aspherical lenses correct for all types of aberrations, letting Sigma house the extended-range super-zoom lens in a compact and lightweight body that measures 70mm in diameter and 78.1mm long and weighs a mere 14.3 ounces. The new lens coating, meanwhile, reduces flare and ghost--a common problem shared by many digital cameras--while also creating an optimum color balance. Other details include a minimum focusing distance of 45cm (17.7) at all focal lengths, a high zoom ratio of 11:1, and a maximum magnification of 1:4.4.
The lens design incorporates an inner focusing system that prevents the front of the lens from rotating, making it particularly suitable for using circular polarizing filters and petal-shaped lens hoods. In addition, the overall length of the lens never changes during focusing, making the lens convenient to handle and easy to use. Finally, the lens's zoom lock switch eliminates "zoom creep" during transport--a convenient addition when traveling. The lens, which includes a metal mount, is backed by a one-year warranty.

The good news which I really didn't expect was to see both lenses produce images that were nearly identical-- I thought for sure Canon's optics would far surpass Sigma's. Color saturation, light exposure through the lens, and detail were indistinguishable. The autofocus worked equally well on both. Both weighed about the same and were about the same size. The Sigma has a 72mm diameter aperture which I liked (so does the Canon). Of course the Sigma is 18-200, and at this time Canon does not have a competing option in the same digital SLR lens class with image stabilization.
The only aspect of the Sigma that differed significantly from Canon's lens was the noise of Sigma's autofocus motor. Sigma produces noticeable motor noise, though it wasn't overly loud. Still if you were shooting in a spot where silence was critical such as a ceremony, it may become an issue but probably not. In comparison, the Canon autofocus motor is silent and fast every time.
Sigma places a locking mechanism on the lens barrel to eliminate any possibility of lens creep (lens extending when pointed down). I doubt this would be a problem with the Sigma anyway. The zoom ring is a little stiff, but not too stiff. The manual focus ring is designed to be used with AF set to off to avoid manipulating the motor when focusing.
The image stabilization works well allowing you to shoot lower light photos without a tripod. I was quite satisfied with Sigma's newest effort here.
I'd say this Sigma makes a great choice for amateur photographers like us looking for a single lens option on Canon digital SLR cameras. The only dissuading factor 'might' be the motor noise if you hope to match Canon's silent motor system. Until Canon produces the same class of lens at a competitive price, Sigma has this round sown up.
UPDATE: "LENS CREEP" September 18, 2007
We did just notice the Sigma lens starting creep for the first time (extend while pointed down). So apparently while the zoom mechanism starts off stiff enough to hold the lens in position, over time it will loosen up enough to move on its own with gravity assisting. Still love the lens though.
I have to say that over time, this lens has worn out its welcome. When I got it, it was a thrill to use, its zoom range and price were its main points for me. However, I would argue that at this price, consistent results are an issue.
Lets looks at this lens's aperture, its not bad wide open at 3.5 but when you use the far zoom side, f/6.3 is exceptionally slow and all of a sudden shooting is blur-tastic.
Aperture aside, when you start looking at your shots at 100% magnification, a lot of the shots will turn out to just be disappointingly soft. The kit lens is sharper in the same range.
Over the past year the "superzoom" range of lenses has exploded. Tamron, Canon, Sigma all have lenses in this range. Sigma's is the cheapest, so if you simply MUST have a superzoom and can't handle the bite of better lenses, this is the choice. However,I would recommend either the Tamron or Canon models over this now.
1. Most of the complaints about reliability seem to come from Nikon owners. Very few from Canon owners. Interesting that so many of these Nikon comments are in the Canon review section.
2. The image quality is exactly what I would expect from a superzoom. Overall, quite acceptable. I would say overall the image quality and sharpness is about equal to the 18-55mm kit lens. That being said, not too bad since the kit lens is well respected by the professional reviewers. My particular sample yields good images in pretty much all of the focal lengths. On my T1i I found that the sharpness settings are set too low anyways. I used a standard value of 5 with the kit lens, but upped it to 7 with the Sigma. I found no problems with noise or artifacting at the 7 setting, but found the images are VERY sharp at that setting. It DOES make a difference changing the setting in the camera even when shooting RAW as all of your settings will be there when you open up the Canon raw converter toolbox. Yes, you can always change the settings later, but why not have it basically right to start. Just one less thing to change in your post processing.
3. Distortion at 18mm is pretty noticable, but once you start getting into fisheye territory, wouldn't you expect to start getting those kinds of results. You can easily eliminate this if desired in photoshop using the "spherize" filter and set it to a small negative value. Pin cushion distortion at higher magnifications is slight to not noticable and can be fixed easily in Digital Photo Professional.
4. Chromatic aberation does show itself at some focal lengths but overall not bad for a superzoom. This can easily be corrected in Digital Photo Professional that comes with Canon Cameras.
5. The Lens hood that comes with the lens works great, although I found that it takes more effort than I would like to snap it into place. I corrected this easily by cutting down by the small indents on the hood with a sharp exacto knife, NOT the lens. This fixed it quite nicely.
6. BAD FOCUS RING DESIGN - Having the focus look and feel almost identical to the zoom ring and having it right next to it is a BIG design mistake. It's very easty to grab a handful of focus ring instead of zoom. This would be OK except the focus could be damaged by doing this. I have already done this on numerous occasions, but so far the focus motor just spins up and no damage done.... so far. MY FIX FOR THIS - The biggest thing needed is a way of differentiating the 2 rings easily, at least visually. What I did was use a 3/32 strip of chrome mylar pinstriping tape right behind the focus ring rubber in the space between the 2 rings. this is wrapped all the way around and joins at the bottom of the lens. It is now VERY easy to see the difference between the 2 rings, creating a reminder so to speak. It also dresses up the lens very professionally. Looks factory (if you didn't know better). The Canon kit lens silver stripe is a chrome mylar pinstripe as well.
7. The zoom feel is quite smooth on my copy at when at a level setting. If the lens is facing up, it's harder to zoom out and if the lens is facing down, it's harder to zoom out. I would expect that since to some small extent that also happens on the kit lens and this is a lot heavier lens. Gravity in action! I do feel that the zoom feel is quite acceptable. for a lens in this price range.
8. Lens weight and construction are quite good for a lens this big. Your camera will weigh in at 1 full pound more than with the kit lens, but the balance seems good. The camera also will look way more professional than it did with the kit lens on it. Free ego boost!
9. The lens cap SUCKS. Plain and simple. Trying to line it up with the lens hood on is an exercise in fumbleitis and it will only be a short time until it winds up falling off and getting lost. Oh well, I guess I'll get one that works better when that happens.
10. In use, the lens is great. Zooming is fast and accurate. This lens is actually slightly faster than the kit lens at 55mm which makes sense since it has a larger objective lens. Basically, it's like having a kit lens that zooms out 4 times farther than the one that comes with the camera.
OVERALL, a great buy for the money if you want a one lens does all solution for a really great price. Also, registering the lens online gets you an additional 2 years of warranty for free (3 years total). Can't beat that. Until I can afford a buzzilion dollars for a high priced zoom, this is it for me. I'm the kind of guy that would much rather have a 1 lens suits all solution than constantly changing lenses and getting crud into the camera, on the sensor, and missing great shots because I have the wrong focal length lens on the camera when that once in a lifetime shot comes along. Yes, for certain professional applications, a nice expensive prime lens can't be beat, but most people in the real wworld couldn't care less about a little more clarity if the photo is great. I agree with that philosophy and I do photography for a living.... using a T1i. Cheap, but great camera. The majority of my work is portraiture and a cast magnesium weatherproof camera is not worth it for me. Are there way better cameras and lenses out there, absolutely, but most people can't see the difference anyways. No need to be an equipment snob.
BUY THIS LENS. Enjoy the savings. If you're doing larger than 24" prints, then think about something more expensive. Spend the extra money on a good version of Photoshop. You'll get more out of that then a slightly better lens anyways.
