Sigma updates 18-200 to 'D40-friendly' status

By dpreview staff on Dec 19, 2007 at 11:21 GMT

Sigma has announced that it is to make its unstabilized 18-200mm F3.5-6.3 DC lens compatible with Nikon's D40 and D40x SLRs which lack an in-body focus motor. Previously 'screwdriver' driven, the new lens will sport an integral motor to shift the glass around and will sit aside the 18-200 OS in Sigma's 2008 range. Making up for the lack of stabilization is the reduction in size and weight - over 24 mm (0.9 in) of length and a handy 215g (7.6 oz) of weight have been lost compared to its big brother which wasn't exactly obese to begin with. Pricing and availability are yet to be announced.

Press Release:

11.1x high zoom ratio lens with a built-in AF motor allowing autofocus with all Nikon APS-C DSLR cameras.

18-200mm F3.5-6.3 DC for Nikon

2007.12.19 - 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 (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 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.

*Vignetting will occur if the lens is used with 35mm SLR cameras, APS format film cameras or digital cameras with image sensors larger than APS-C size, including 5:4 and FX format of Nikon D3 camera.

Petal-type Hood (LH680-01) supplied
