Sigma launched today a new Four-Thirds system compatible, large aperture zoom lens; Sigma 18-50mm F2.8 EX DC Macro. This lens has a large aperture of F2.8 throughout the entire zoom range. A minimum focusing distance of 20cm (7.9) and a maximum magnification of 1:3, makes it ideal for close-up photography. Specially designed to suit the characteristics of digital SLR cameras, this lens provides a high level of optical performance. Its design incorporates both glass-mould and hybrid aspherical lens technology which offers extremely high image quality as well as a compact and lightweight construction. Minimal vignetting and superior peripheral brightness is ensured.

Special Low Dispersion (SLD) and Extraordinary Low Dispersion (ELD) glass elements provide excellent correction of color aberrations. The super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras. High image quality is assured throughout the entire zoom range. An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the petal-type lens hood (supplied) plus circular polarizing filters. The introduction of this new lens increases Sigma's lens line-up for Four Thirds mount to a total of eleven models. With Four Thirds cameras, the focal length will be equivalent to 36-100mm.
