Sigma 28mm F1.4 DG HSM | Art Lens - L-Mount
Sigma SKU: 441969 | Helix SKU: SM441969
*Expected delivery Fall 2019*
The new Sigma wide-angle model stands out with its thoroughly corrected magnification chromatic aberration and sagittal coma flare, as well as completely minimized distortion thanks to its optical design. It features water- and oil-repellent coating on the front lens element and its overall dust- and splash-proof structure ensures excellent performance even in the most challenging shooting conditions. The high-speed AF, thanks to the HSM (Hyper Sonic Motor) with an updated algorithm, captures the perfect moment instantly. Available in Sigma, Nikon, Canon and Sony E camera mounts, this lens is a great contender for street photography, as well as shooting landscapes and night skies.
