The Sigma 18-200mm f/3.5-6.3 II DC OS HSM Lens for Pentax AF 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 Pentax digital SLR camera with an APS-C size sensor*. It includes a Hyper Sonic Motor (HSM) for quiet, high-speed autofocus.
The 18-200mm's optical design incorporates aspherical lenses, with FLD and SLD glass, which provides the utmost correction for color 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.
