The Sigma 60mm f/2.8 DN Art is a compact short-telephoto lens. Complementing its modest size is a sophisticated optical design, which uses one SLD element and one aspherical element to reduce chromatic and spherical aberrations for improved clarity and a sharpness. A Super Multi-Layer Coating is also featured and minimizes flare and ghosting for heightened contrast and color accuracy when working in strong lighting conditions. Complementing the optics is a Linear AF motor, which realizes smooth and quiet autofocus performance, and a rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
