Sigma 18-200mm f/3.5-6.3 DC OS Lens for Canon

The Sigma 18-200mm f/3.5-6.3  DC OS HSM Lens for Nikon offers an "all-in-one" super-zoom lens solution, from wide-angle to long telephoto. It provides the equivalent focal range of approx. 27-300mm when used with a Nikon digital SLR camera with an APS-C sized sensor. This lens has the OS (Optical Stabilizer) system, which minimizes image blur caused by camera shake, and offers the equivalent of shooting at a shutter speed 2-3 stops faster. This allows handheld telephoto zoom shooting even in poorly lit conditions. It also includes a Hyper Sonic Motor (HSM) for quiet, high-speed autofocus.

 

The 18-200mm's optical design incorporates aspherical lenses and SLD (Special Low Dispersion) glass, which provides the utmost correction for all types of aberrations. It also enables this extended super-zoom lens to be housed in a compact and lightweight construction.

 

DC lenses are exclusively designed for digital SLR cameras. The image circle (rear of lens) is sized to match the smaller dimensions used for the APS-C image sensor found on many digital cameras. As a result these lenses are also more compact and lightweight, and are better matched to digital SLR cameras.
