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.

Outstanding Lens!
I don’t know alot about lenses but my wife wanted this for her birthday. I purchased off of Amazon and my wife loves it. The only drawback is she says when she’s taking pictures in public it makes her look like she knows what she’s doing. HAHA!
New to DSLR’s and this lens is a perfect 1st step
I’m new to the world of SLR’s. I’ve been using point and shoot for years but broke down and bought a Canon dSLR a few months ago. I found the stock lens limiting so I bought this lens to supplement my shooting. I’m glad I did - it is moderately priced and you get a lot for your money. It works right out of the box and takes great pics!
Zoom creep a problem
I bought this as my first upgrade lens for the Canon xti. As a new user, it is hard to tell if the OS actually works, because on or off it takes pictures with less blur than the standard 18-55mm lens that came with the camera.
The zoom is very un-smooth in the amount of twising force required. I wanted to take picures of some birds in trees, but when pointing the camera upward, the zoom tends to automatically move from the 110 to the 35mm position. I read here there is a zoom lock, but it only locks in the 18mm position, and is useless for zoom creep.
