The Sigma Corporation is pleased to announce the launch of the new 18-200 F3.5-6.3 DC lens. This high zoom ratio lens is exclusively designed for digital SLR cameras and capable of covering a wide range of focal lengths from wide-angle to telephoto. Two Special Low Dispersion (SLD) glass elements and two hybrid aspherical lenses offer the utmost correction for all types of aberrations, and enable this extended range super zoom lens to be housed in a compact and lightweight construction of 70mm (2.8”) diameter, and 78.1mm (3.1”) in length, and weighing just 405g/14.3oz. The new lens coating reduces flare and ghosting, which is a common problem with digital cameras and also creates an optimum colour balance. This lens has a minimum focusing distance of 45cm (17.7”) at all focal lengths and has maximum magnification of 1:4.4.

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 traveling.
