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 hood (more…)

Good price and quality. Soft focus.
This is an universal lens. When you put in your camera you don’t feel to change it.
Pros:
1. Tele zoom. You can catch people without being noticed.

Pretty good lens for the $.
This lens works pretty good with my Nikon D40 and I have made great shots using it.
After about a year of use I got no complaints and would buy it again in a heart beat…

amazon buyers beware
I just got this item and took some pics. Picture quality looks ok to me – but, I am just an amateur, what do I know?

Practical…but image quality is disappointing.
This lens is very practical given its range. It’s a perfect match to the entry level D40/60 with its built in focusing motor.

Disappointing, but maybe a bad copy
I already had the Sigma DC 18-200 non-OS lens and was very pleasantly surprised with the overall balance of versatility vs. image quality.

Struted at track meet
The lens performs well when you do not put in situations when you know it will not perform well. There are enough reviews out there to inform you of the lens weakness, low light…

this lens is big
I use this lens on my Canon Rebel XTI as a replacement for the EF-S 18-55 1:3.5-5.6 II that come with the kit.

If you want sharpness, this isn’t what you are looking for
I bought this lens from Amazon last month and sold it this month. The reason … its not sharp enough.
Focal length is great. The lens is well built.

OS/AF Mechanism Fails
Go for the Nikon, or buy the lens in your local store, so you can return it within the one year warranty.

Amazon should not be selling this Lemon Product
I purchased this lens thinking it was a good value, and I got disappointed when the lens completely failed in the middle of a trip after getting the famous error message.
