Convenient but you loose quality

Excerpt: I have used this lens on three holidays. Two to outback Australia and one to Italy. It is very convenient to have such a range without having to change lenses. But the compromise is quality and colour. I owned an EFS-17-85 with my 30D and I got this with my 50D. I have decided to go back to using my 17-85 - it's a better lens. I have just taken some shots of a couple of subjects with both lenses and the 18-200 put a yellow colour cast on the photo.
Conclusion: I can live with all other shortcomings of the lens (distortion, vignetting, lack of sharpness etc) for the sake of the huge 18-200mm zooming range. But, I did some testing, and found that the zooming range is not a true 18-200mm. For example, I set the lens at 200mm, and took pictures focusing at a series of distances (4 ft, 5 ft, 10 ft, 20ft). When focusing 4 ft away, the 200mm focal length was found to be actually only 110mm.
Excerpt: This was the first lens I ever bought for my Rebel XS. I wanted to upgrade for the kit lens to have a greater focal range than the standard 18-55mm lens. This lens is defiantly a super zoom lens, and on 1.6x sensor it's the equivalent of a 29mm to 320mm lens; a nice multipurpose range. <br /><br />But that's where the pros end. For the price, the construction of this lens is not great; it's still plastic, though it does feel very heavy (positive and negative thing).
Pros: Easily Interchangeable, Image stabilization, Zoom Range
Summary: I do not recommend this lens - I recommend saving your money and buying a higher quality lens.
Pros: A great lens to bring along if you only have one, because it offers a nice range of focal lengths. I've brought it on many trips.
Cons: Disappointing quality. I'm fairly active and this lens goes with me on many outdoor activities. I've had to take it in for repair twice, when there has been friction with zoom in/out, and the lens lock functionality failed. I expected better quality from a lens at this price point.
Excerpt: I purchased this lens hoping to get a good everyday lens. It does not live up to its cost or its billing as being very close to L quality. Vignetting around the edges results when zooming even half way and at 200mm it is extreme. This makes this lens virtually unuseable. The focus is also somewhat soft compared to L glass and focusing very slow. I would not recommend this lens.
Conclusion: I loved this lens until I used the lock. The lens will extend under its own weight so they provided a lock to hold it. I found this feature after about 6 months when I read the manual. I turned the lock on and it broke immediately. There was a rattle in the lens and soon the lens stuck. This is just what happened to another reviewer. Too bad. I used to love this lens but the lock feature was defective.
Conclusion: I have owned this lens for about 6 months now. The lens is quite heavy so there is a zoom lock to keep the lens from extending. After a few months, this switch didn't work so well and the lens would extend on its own once in a while. Eventually something broke inside the lens and now it doesn't zoom out all the way. I can hear plastic rattling inside the lens. The optics were ok for the price. Definitely not the sharpest.
