Widely acclaimed and now more compact than ever, this is the smallest zoom of its type. Just over 3 inches long with a maximum diameter of 3 inches, the whole lens weighs just 18.2 oz.
Incorporates one aspherical lens element in the rear and one Special Low Dispersion element in the front lens group.
Internal focusing eliminates front lens barrel rotation, allowing for easier handling and the use of polarizing filters.
Features superior optical performance. Throughout its entire zoom range, it offers a minimum shooting distance of 19.7 inches. Its circular diaphragm provides natural, soft focus foregrounds and backgrounds, while keeping the main subject in sharp focus.
Every detail was designed from the photographer's point of view — evident in such ergonomic touches as the easy to use manual focus ring and the smooth feel of the focus ring and zoom control.

The sigma 28-200 IF aspherical lens combines compact design with ease of use features. The front ring does not rotate even when using manual focus. This means no more adjusting your polarizer. Also the manual focusing ring is located directly in front of the zoom ring which gives a little easier control between the two. The quality of my photos did not seem to suffer even at the 200mm end. I did notice a small amount (hunting) on distant or abnormal subjects, otherwise I have had no problems. In the end this is a great lens for a beginner or amatuer and it won't cost you an arm and liver get it. Smile photo and video which has an internet store that carries it for around $189.00. Don't qoute me on that though, prices always change.
