Sigma 18-200 F3.5-6.3 DC Lens for Nikon

Sigma has added an internal motor to its unstabilized version of the 18-200mm lens in order to make it compatible with the Nikon D40 and D40x. If you recall, back in September, Sigma released their 18-200mm OS version for Nikon.

Press Release:

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.

Sigma 10mm and 4.5mm Lenses Announced

Sigma has announced a couple of new fisheye lenses – the fast 10mm f/2.8 and the crazy-wide 4.5mm that stands alone with no real competition in the crop-sensor category. A couple of noteworthy points – first, both are DC lenses, which means that they are only for cropped-sensor cameras like the Canon Rebel and 40D series (along with all of Nikons DSLRs). These will not work properly on the Canon 5D, 1D or 1Ds series cameras. [Read more...]

Sigma’s 18-200 Stabilized Lens Available in Nikon Mount

It took awhile, but the Sigma 18-200mm OS lens is now available in Nikon mount. If you recall, Sigma held up the release for the Nikon mount in order to add the HSM autofocus motor so that the lens would be fully compatible with the Nikon D40 and D40x. If you’re shopping for a nice superzoom lens and don’t want to fork over $750 for Nikon’s own AF-S 18-200mm, the Sigma lens comes in at a more reasonable $550.
