18-200mm f/3.5-6.3 DC added to Sigma's digital line-up - Compact, lightweight superzoom lens with high 1:11 zoom ratio
The lens design incorporates an inner focusing system, which prevents the front of the lens from rotating, making it particularly suitable for using circular polarising filters and petal shaped lens hoods. The overall length of the lens does not change during focusing, ensuring convenient handling and ease of use. A zoom lock switch eliminates zoom creep during transportation, a convenient addition when travelling.
