Product Description Exclusively designed to suit the characteristics of digital SLR cameras. The image circle was designed to match the size of the image sensors of most digitalSLR cameras and this has resulted in a compact lightweight lens. Sigma has incorporated an HSM Hyper Sonic Motor into the 18-50mm F3.5-5.6 DC HSM, that now allows quite and high-speed autofocusing with all Nikon DSLR cameras. Aspherical lens and Super Multi Layer Coating are used for excellent lens performance. High image quality is assured throughout the entire zoom range. Compact-Lightweight zoom lens has a maximum diameter of 60mm (2.4in.), overall length of 69.6mm (2.4in.) and weight of only 250gr (8.8 ounces) and filter size of 58mm. Compact dimensions offers superb handling and mobility. The use of aspherical lenses provides correction for various aberrations throughout the entire zoom range and produce high level of optical performance. Sigma took digital characteristics into consideration when designing the lens power layout and created the most suitable lens that makes high quality images a reality throughout the entire zoom range. We used the most appropriate coating for digital products to cut down flare and ghost caused by digital SLR cameras and to produce the best color balance. It can be used with the supplied lens hood to block out extraneous light. 18-50mm F3.5-5.6 DC HSM zoom lens has a minimum focusing distance of 25cm (9.8in.) at all focal lengths and is capable of macro photography with a maximum magnification ratio of 1:3.5. The focus ring provides easy operation in manual mode. A distance scale on the focus ring is an easy to use and convenient addition.
