Sigma 777109 Overview

The Sigma 18-200mm f/3.5-6.3 DC lens is specially optimized for digital SLR cameras, and offers an "all-in-one" super-zoom lens solution. This lens provides the equivalent focal range of approx. 27-300mm when used with a Pentax digital SLR camera(*).

It's design incorporates aspherical lenses and SLD (Special Low Dispersion) glass that provides the utmost correction for all types of aberrations and enables this extended super-zoom lens to be housed in a compact and lightweight construction.

DC lenses are exclusively designed for digital SLR cameras. The image circle (rear of lens) is made to match the smaller dimensions used for the image sensor on digital cameras. As a result these lenses are also more compact and lightweight, and are better matched to digital SLR cameras.

(*)Note: Not compatible with 35mm cameras or digital cameras using full-size image sensors.

Super Multi Layer (SML) coating reduces ghost and flare
Two pieces of Special Low Dispersion (SLD) elements and two hybrid aspherical lenses provide high quality images throughout the entire zoom range
The lens design incorporates an inner focusing system, which prevents the front of the lens rotating, making it particularly suitable for use with circular polarizing filters and petal shaped lens hoods
A magnification scale is displayed on the lens barrel for each focal length, ensuring ease of use
