Sigma 17-70 f2.8-4.5 DC Macro
This revolutionary lens has a minimum focusing distance of 20cm (7.9”) throughout the entire zoom range. A maximum magnification of 1:2.3 enables extreme close-up photography. An impressive achievement for a standard zoom lens. The new lens design and multi layer lens coating reduce flare and ghosting, a common problem with digital cameras.
A Special Low Dispersion (SLD) lens and two aspherical lens elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range.
