Features

The Sigma 18-50mm F2.8 EX DC MACRO HSM features 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.

The lens features special Low Dispersion (SLD) and Extraordinary Low Dispersion (ELD) glass elements provide correction of color aberrations. The super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras. It also features an inner focusing system that eliminates front lens rotation, making the lens particularly suitable for using the petal-type lens hood (supplied) plus circular polarizing filters.
