Product Description
The Sigma 18-200 F3.5-6.3 DC OS HSM Lens incorporates an Optical Stabilizer function and is exclusively designed for digital SLR cameras. It is perfectly suitable for low light conditions whether indoors, at dusk, or in telephoto range. This system uses two sensors inside the lens to detect vertical and horizontal movement of the camera by moving an optical image stabilizing lens group, to effectively compensate for camera shake. It also automatically detects panning movement of the camera and compensates for camera shake when shooting moving subjects such as motor sports. 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. Since the inner focusing system means the front of the lens does not rotate, optional circular polarizing filters and the supplied petal-type hood can easily be used. A magnification scale is displayed on the lens barrel, ensuring ease of use. A zoom-lock switch mechanism is provided to prevent the lens from creeping due to its own weight. 69.3 - 7.1 degrees (Sigma SD format) angle of view 7 Diaphragm Blades F22 Minimum Aperture 45cm / 17.7 Minimum Focusing Distance 1 - 3.9 Maximum Magnification Petal Lens Hood Dimensions - Diameter 79mm x Length 100mm Weight - 21.5 ounces (610 grams)
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.

 SIGMA AF 18-200mm January 6, 2009
Rodney B. Roberts (PALISADE,COLORADO)
I HAVE BEEN USING MY NEW LENS FOR WEEKS AND AND ALL I HAVE TO SAY ABOUT THEM IS THEIR "GREAT"!!! I'VE SHOT CLOSE-UPS AND DISTANCE (ONE WITH TWO BUCKS FIGHTING-HORNS LOCKED) AND THE IMAGES HAVE TURNED OUT SUPER. MY FRIEND HAS THE TWICE AS EXPENSIVE NIKON EQUIVALENT AND WE ARE SHOOTING PRETTY MUCH ON PAR. I AM USING THE NIKON D90 AND LOVING IT. MY ONLY CON ABOUT THE SIGMA IS THAT IT IS A LITTLE BULKIER LOOKING THAN HIS NIKON 18-200mm BUT THAT IS ONLY COSMETIC AND I CAN LIVE WITH THAT AND THE PRICE DIFFERENCE!!
GREAT SHOOTING TO YOU ALL!!! RR OF COLORADO
 $[...] cheaper, same specs as Nikon equivalent, that's too much value. December 21, 2008

This is worth the trade down to Sigma, which has been making decent lenses for years. $[...] bucks, it's crazy insane not to buy. With the savings you could buy a decent tripod or the Nikon 50mm f/1.8D AF Nikkor Lens, excellent for low light and some lens filters. I read the reviews for this 18/200mm lens and too many people liked it for the value and quality and I agree. This is the best walking around lens especially at the zoo, you get the tight head shot or the wide shot. Best general lens, jack of all shots.
OS Rocks December 16, 2008
Aaron T. Veino (Boston, MA USA)
Great lens for the price... can't complain about this lens. I got it over the Nikon due to pricing, and I am satisfied. I haven't had any lens creep yet (which is pretty much the only thing that I am worried about) but I keep it locked whenever I'm not zooming around with it.
The OS is perfect allowing you to effectively shoot at 200mm... it eats up a little bit of extra battery, but definitely is working.
If you can afford it, go for the Nikon, but if you dont have the extra dough to throw around I would pick this up no sweat. Excellent walk around lens...
 Half the price but half the qaulity November 29, 2008

This is the second Sigma Lens I've owned and the second one I've returned. Common to many Sigma lenses is zoom creep, inaccurate focus, and heaviness. The reason I give it 3 stars?? If you use your DSLR more for snapshots and need a huge zoom range this lens is a good alternative to carrying two lenses or spending $600 on the Canon equivilant. If you want your pictures to be in focus and have a lighter lens, smoother focus ring and have some extra money in your budget, go with a Canon lens
Sigma AF 18-200mm f/3.5-6.3 DC OS Zoom Lens for Nikon D40 November 22, 2008
Nataraj (43.1N 89.35W Earth)
I have used this lens with my D40 for about a month. I was concerned about the relative slowness of the lens, especially at full zoom, but the OS makes up for it allowing me to shoot successfully at slower shutter speeds. Optically the lens seems fine to me. It DOES autofocus with the D40. Combined with a Sigma 30mm HSM prime lens, I have everything I need for most situations. This lens is significantly larger and heavier than the Nikon kit lenses. You will know that you have this 1-lb lens hanging around your neck! I am very satisfied with this lens. Recommended to replace both the 18-55 and 55-200 Nikon kit lenses.
