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 the telephoto range. This system uses two sensors inside the lens to detect vertical and horizontal movement of the camera, and effectively compensates for camera shake by moving an optical image-stabilizing lens group. 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 Fully compatible with All Nikon Digital SLR cameras including the D40 and D40x 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 Nikon 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.

D. Tom Said: Sigma 18-200 ( Nov. 15th 2009 )
All around travel lens, saved alot of weight by just having one lens, not as sharp or fast as the other Canon lenses but for the price it's well worth it.
John L. Mast Said: A fantastic lens for the prosumer. We highly recommend this lens for the money! ( Oct. 23rd 2009 )
My wife and I purchased this lens prior to our trip to Germany. After great debates and hours of research we decided that this lens offered the extensive features that we wanted within the budget we set. Upon arrival I was amazed from the moment I took the lens out of the package. After reading reviews and debating between this lens and other more expensive alternatives I was expecting something with lower quality. I was very happy to see that this lens was built with terrific quality and was very stout. We are using it with our Canon Digital Rebel XTi and we couldn't have been happier with the performance. This is our first telephoto lens that we have purchased so please know that we don't have much to compare it to. However if you are like us "prosumers" on a budget and hunting for a nice lens in this price range, look no further.
Wilburt Hanisco Said: Lens faults ( Oct. 16th 2009 )
I purchased this lens to attach to a Nikon D-60 SLR camera. It was to be used in my many excursions with a travel/exchange group. This year we went to Turkey. At first I was satisfied with the lens but it commenced to give me camera errors that read sort of," Lens not fully attached to camera". To correct I locked the lens and tightened. This happened approximately 15-20 times in an eighteen day period. Also, the lens developed numerous spots. In handlind the lens while on the camera I either put the lenscap back on, or cupped my hand over the lens to prevent burning, and was in a very dry area. I would try another one in the future if I can be assured the manufacturing and quality assurance has improved. I am NOT an expert in lens quality, but believe this particular lens is and was faulty.
Shining Bo Said: wonderful lens ( Sep. 12th 2009 )
I received the len which was packed carfully. The len itself is very beautiful and the picture is beautiful too.
CKR Said: Great lens... for the short time it lasted ( Aug. 23rd 2009 )
Loved this lens when it worked... however now, only one year later, this lens doesn't work! Short circuits new Nikon D90 camera and won't AF on D50. I can't afford to be buying a new $500 lens on a yearly basis - I'm extremely disappointed in Sigma's longevity.
