 Sigma 18-200mm F3.5-6.3 DC lens
This 18-200mm F3.5-6.3 DC lens has a minimum focusing distance of 45cm (17.7in) at all focal lengths and has maximum magnification of 1:4.4. The Sigma lens design incorporates an inner focusing system, which prevents the front of the lens from rotating, making it particularly suitable for using circular polarizing 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.
