 Sigma 18-200mm lens for Nikon : We got news from Sigma Japan. Sigma is pleased to announce the launch of the new Sigma 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 auto focusing 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 (2.8”) in diameter, 75.6mm (3.0”) in length and 395g (13.9oz) makes it ideal for field work.
