The Sigma Corporation is pleased to announce the launch of the new 18-200mm F3.5-6.3 DC for Nikon. This high zoom ration lens, designed exclusively for digital SLR cameras, covers wide angle to telephoto. The built-in motor is capable of autofocusing with all Nikon DSLR cameras. Two SLD (Special Low Dispersion) lenses and two Aspherical glass elements provide excellent correction for all types of aberration. Sigma's super multi-layer coating reduces flare and ghosting and provides high image quality throughout the zoom range. The compact and lightweight construction of 70mm in diameter, 75.6mm in length and 395g (13.9oz) makes it ideal for field work. This lens has a minimum focusing distance of 45cm and a maximum magnification of 1:4.4. An inner focusing system also eliminates front lens rotation, making the lens particularly suitable for using the petal lens hood and circular polarizing filters. A zoom lock switch mechanism is provided to prevent the lens from creeping due to its own weight.
