Sigma recently updated its 18-200mm super zoom lens to be D40/D40x friendly with a built-in auto focus motor. The press release states,

Sigma Corporation is pleased to announce the launch of the new 18-200mm F3.5-6.3 DC for Nikon. This high zoom ratio lens, designed exclusively for digital SLR cameras, covers wide angle to telephoto focal lengths. 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 (2.8″) in diameter, 75.6mm (3.0″) in length and 395g (13.9oz) makes it ideal for field work. This lens has a minimum focusing distance of 45cm (17.7″) and a maximum magnification of 1:4.4. An inner focusing system also eliminates front lens rotation, making this 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.

This is apparently not a professional grade lens (lack of the EX label), but it should a good candidate for people who are looking for a light weight super zoom intended for walk-around and travel lens. For people who wants more reach, the Tamron AF18-250mm F/3.5-6.3 Di-II LD Aspherical (IF) Macro, which also has a built-in AF motor and is D40/D40x friendly, is also worth considering.

Sigma actually has four different 18-200mm zoom lenses. If you are confused by the Sigma’s lens offerings, you may want to check out its complete lens line-up.
