Amazon.com Product Description
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.
Product Description
This high ratio zoom lens incorporates Sigma`s original OS (Optical Stabilizer) function and exclusively designed for digital SLR cameras. It is perfectly suitable for low light conditions, indoors, at dusk and telephoto range. SLD (Special Low Dispersion) glass and aspherical glass provide excellent correction for all types of aberrations. This lens has a minimum focusing distance of 45cm (17.7) throughout the entire zoom range and has a maximum magnification of 1:3.9. The inner focusing system is suitable for using a petal-type lens hood supplied and also circular polarizing filters.

 Very pleased August 21, 2010

So far I'm quite pleased with the lens. I have not conducted extensive tests but based on the photos I've made so far, I like it.
Excellent...But... August 10, 2010

I ordered this lens for a trip to Alaska; I wanted something with a wide range so I could avoid swapping glass every time I turn around. At about 1/2 the cost of the Nikon version, this looked like a winner. It did everything I wanted, quick steady focusing, sharp pictures with good color but it weighs a ton! Reviewers bash the Nikon plastic DX lenses but when it's slung over your shoulder all day... My other complaint is that the focus ring is way too wide and in the way for an AF lens. Whilst reaching for the zoom, I would grab the focus and "zip" the gears (hope I didn't break anything!!!). Other AF lenses sport an atrophied focus ring and this lens would benefit from a similar design.
Overall, an excellent value and well recommended if you don't mind the weight.
 Fantastic until it broke August 2, 2010

The zoom range for this lens makes it a great all purpose "non-pro" lens. Perfect for travel as it goes from nominal wide-angle to telephoto. That's the good news.
The bad news is after two years of not-too-frequent use, I turned the zoom ring and something snapped inside. The lens is toast -- I can physically move the lens barrel in and out for zoom, but the focus doesn't seem to work -- auto or manual. It's headed back to Sigma for repair.
pictures are not consistent July 24, 2010

i have been using this lens for a little while and its mix reaction let me make clear i am not a pro or advance photographer but average Joe i am speaking in plain language it takes a beautiful pictures and not so beautiful pictures i am taking about sharpness some pictures are very sharp and great looking and some feel like they are out focus or fuzzy just a little bit i was planing to use this lens at wedding of my cousin thats why i bought this lens but i think i am going to use Nikon 18-55 just to be safe and use this only if i need it on camera LCD Display it looks fine but when you see in computer thats when you see very clearly and this is not an issue all the time but its their i just take lots of pictures so in case pictures that you want is not so clear you have many choices to chose from would i recommend this lens that depends on your budget if you can't spend lots of money on lens like me and you have budget of 350 to 375 this is a very good lens Nikon 18-200 is 950 and this is around 360 which is little more then 1/3 the price but its not 1/3 the quality i don't have Nikon 18-200 but i have seen picture posted by users on amazon and they look very good this lens takes very good pictures most of time it some pictures i am not happy with focus wise they feel soft then again Nikon lens user may get those pictures but they are not going to post them on amazon but you have to have 18-200 lens and don't have money to buy Nikon or canon i would definitely recommend this lens
A good lens... July 21, 2010
