Description The Sigma 24-70mm f/2.8 DG DN Art is a versatile wide-angle to portrait-length zoom characterized by its f/2.8 constant maximum aperture. The bright design suits working in available lighting conditions and also affords increased control over depth of field. The optical design incorporates a series of low dispersion and aspherical elements that greatly reduce a variety of aberrations in order to achieve high sharpness, enhanced clarity, and improved color accuracy. Both Super Multi-Layer and Nano Porous Coatings have also been applied to improve contrast and color rendering by suppressing lens flare and ghosting when working in strong lighting conditions. Complementing the optical attributes, this lens also sports a stepping AF motor, which yields fast, precise, and notably quiet autofocus performance. At the wide end of the zoom range, a maximum magnification ratio of 1:2.9 suits working with close-up subjects and an 11-blade diaphragm contributes to a pleasing bokeh quality. Additionally, a weather-sealed design benefits working in trying environmental conditions.
