Designed for reflex digital cameras, the 18-50mm F2,8 DC EX Macro from Sigma is a large aperture zoom lens with a constant maximal aperture of F2.8 for all focal distances. Equipped with an ingenious system of SLD, ELD and aspheric glass lenses, this device offers excellent performance in a compact package.
Photos will turn out bright with very little vignetting. What's more, the Super Multi-Layer lens treatment reduces ghosting and flare. The 18-50mm F2,8 DC EX Macro lens also features a minimum focal distance of 20 cm, with a maximum magnification of 1:3:0
