Sigma 28-200mm f/3.5-5.6 DG Macro
(From Sigma lens literature) A compact, high-zoom ratio lens, ideal for full-frame digital SLR cameras. This lens covers all the focal lengths from 28mm wide angle to 200mm telephoto, the most frequently used focal length range. With a maximum diameter of 70mm (2.75 in.) and length of 77.7mm (3 in.), it has a compact size. It packs a lot of performance in a compact package. Portable and mobile, the lens can be carried anywhere, so it is ideal for travel and other types of photography.
This digitally optimized ultra telephoto lens is equipped with a new multi-layer coating technology that reduces both flare and ghosting. This also ensures an accurate color balance and high definition results.
The aspherical lens contributes more than compact size: it also delivers improved image quality. The use of aspherical lens elements in both of the front and rear lens groups effectively compensates for various aberration throughout the entire zoom range.
This design allows for stability and compactness in design as changes in focus are made in an internal lens grouping. This also gives the advantage of a non-rotating front lens assembly, which is of great benefit when using polarizing filter and Petal-type hood.
At the 200mm telephoto setting, the lens is capable of macro photography with a 1:3.8 maximum magnification. The minimum focusing distance is 48cm at all zoom settings. And with a photography magnification scale displayed on the lens barrel, the lens is user friendly.
A zoom lock switch mechanism is provided to prevent the lens from creeping due to its own weight, and to avoid the danger of the lens receiving a shock while it is being carried.

naturally, such a lens is not so sharp as a single lens, dued to
this enormous zoom range;it is ok.
wide ope a few weak, but stopped down to f11 really sharp
and high contrast.
I am content with it.CA's must be eliminated and sharpness could be improved by PhSh
5 out of 10 points and not recommended by eyrieowl (3 reviews)wide range, relatively compact, macro functionality, priceslow, not very sharp, doesn't go wide-enough on aps sensor, color cast
This was my first lens for my Nikon d50. Which was my first true digital camera (other than 3mp point-and-shoot i'd gotten with my printer). prior to that, i'd been shooting on a venerable Canon AE-1. I had a cheapie 28-210 zoom on that body (no, I didn't know much about lenses), so when i moved into digital, i went for the same range. this lens...was a decent starter lens to begin to learn digital photography. but i am not sure it'll be going back on my camera again. i'd rather forgo the range for quality and speed. the price wasn't bad, and i certainly have learned from the lens, so, it's not all bad. training wheels for my dslr!reviewed August 21st, 2007 (purchased for $179)
