Product Description

Amazon.com Product Description

Designed exclusively for Nikon digital SLR cameras, the Sigma 18-200mm f/3.5-6.3 high-zoom-ratio lens covers a host of wide angle and telephoto focal lengths. The lens includes a built-in motor that provides high-speed autofocus, along with two special low dispersion (SLD) lenses and two aspherical glass elements that correct for all types of aberration. Sigma's super multilayer coating, meanwhile, reduces flare and ghosting and provides topnotch image quality throughout the zoom range. And thanks to the inner focusing system, you don't have to worry about front lens rotation, making this lens particularly suitable for petal lens hoods and circular polarizing filters. Other features include a minimum focusing distance of 17.7 inches, a maximum magnification ratio of 1:4.4, a compact and lightweight housing, and a zoom lock switch that prevents the lens from creeping due to its own weight.

4.0 out of 5 stars Great Lens for the Price!, June 24, 2005

By	S. Kanter (New York, NY USA) - See all my reviews (REAL NAME)

I disagree with the previous poster. I think this lens is pretty great.

The quality is exceptional for a lens of this price and range.
There seems to be a controversy regarding how focal lengths of lenses are measured; from what I've read, the lens does go to 200mm if measured at infinity.

In the real world, the lens takes fine pics as long as you have enough light. The size and weight is perfect for a walk-around lens. My Rebel XT with this lens (and the Hakuba hand grip) is a perfect fit, and feels great to carry around and shoot. To get better optical quality at this range, you would need to get a few lenses that each cost a lot more. There is nothing quite like this, except for Tamaron's 18-200, which I hear doesn't compare favorably to the Sigma.

It seems that Sigma has quality control issues, so I would buy
the lens from a local dealer that has a return policy. Test the lens, and if you don't think it's up to par, return it for another.

5.0 out of 5 stars My choice for traveling, June 30, 2006

By	ShutterFlash (Portsmouth, NH USA) - See all my reviews

I got this lens a day before taking off for an eight day trip, and shot over 1800 photos with it. Though not the fastest lens out there, it did everything I wanted it to, both in the wide angle and the telephoto. I think I put it through a pretty thorough test over that week, and have these comments:
1. If I can only take one lens, this would be it.
2. I missed not having a macro feature, but I got close enough with the telephoto to make up for it in some cases.
3. The auto focus works fine in normal and bright lighting, but in dim lighting (like in a museum) it became confused and I used the manual focus option instead.
4. This is my third Sigma lens, and I haven't had any quality control problems with any of them.
5. I have no experience with high end Canon lenses for my Canon DSLR so I can't make a comparison, but I'm fully satisfied with the optics of this lens.

Excellent value and versatility.

3.0 out of 5 stars THE 'one and only' travelling lens., September 25, 2005

By	TheTeh "TheTeh.Com Photography" (London United Kingdom) - See all my reviews

3 stars because of:
1) soft corners at 18mm (f3.5)
2) vignetting at 18mm (f3.5)
3) lens creep (self extension of lens barrel while walking) if not retracted/lock at 18mm

This lens has the most useful range one can possibly have. It has become my only lens for short travelling trip when I don't want hassel of changing lens. I took only this lens with my Canon XT to Amsterdam (5days) without missing my other lenses at all. Here are some photos taken with this lens in my website:

For this price range (other than the Tamron 18-200) there is no other lenses that can compete!
