Sigma 18-50mm f/2.8 EX DC Macro Lens

The Sigma Corporation is pleased to announce the launch of the new 18-50mm F2.8 EX DC MACRO lens.

Sigma Press Release

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, making 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-mold and hybrid aspherical lens technology which offers superior peripheral brightness, extremely high image quality as well as a compact and lightweight construction. 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.

FEATURES

· Minimum focusing distance of 20cm with a maximum magnification of 1:3.
