I couldn't believe this lens was under 100 dlls. I've also got one in the 55-200mm range and it's just as good as this one.
I bought it because a friend of mine dropped the camera with the original nikon on it and it broke the support. I chose it because I like a lot the other one I have. This one autofocuses just as or faster than the nikon that comes standard with the camera.
Personally I prefer this one because it feels sturdier and the finish makes it look less toy-like. It also has a metal attaching ring, not like the nikon that has thin plastic one.

When I purchased this lens, I was not 100% convinced that it would work with my Nikon D40's autofocus mechanism. It does. I purchased this as a replacement for for my 18-55mm lens that came with my D40. The autofocus had stopped working on that lens. Since I often used it when shooting casual pictures of family and friends, the autofocus was very important.

I rated this lens a four because it focuses somewhat more slowly than the Nikon lens it replaced. The performance is not significantly different from the Nikon lens.

Given the option between purchasing this lens or paying the half again as much for the Nikon lens, I would go with the Sigma lens. The difference in performance is not significant enough to dissuade me from Sigma.

This Sigma lens works spectacular with the Nikon D40X. It's a great deal for a great price. With the Nikon D40X you have to have a lens that has AF because there is no motor for it in the Nikon. This is why I purchased this lens in particular. I've been able to take some amazing close ups. I took a photo of a rose and the detail in the rose was amazing! You could see the veins in the petals with vivid detail. I would recommend this lens to anyone with a digital camera for which it fits, especially those cameras without AF motors, owned by people who would like to have (AF) auto focus and fantastic photos.

If you have never owned a sigma they are every bit as good as a Nikon for all but the most demanding professional photographs. I'm sure the expert photographer can tell the difference but my dad (who teaches photography at a local college) swears they are every bit as good for a fraction of the price

IT's one of the better lens that doesnt get much prop., it works great with my D5000.
- take great picture, (little under expose indoor but D-lighting always adjust, outdoor create smooth and very soft bokeh)
- decent focus and great close up and good wide-angle shot.
- cant beat the price for this value comparing to the kit lense, save that money for the Nikon-55-200m or the Nikon 35mm 1.8 AF-S.
- Made from Japan!
Cant go wrong with this lens, oh make sure to add the Hoya HMC 58mm UV protection with the extra $ saved. only about 22$!
