An optically advanced wide-angle prime, the Canon EF 35mm f/1.4 DG HSM Art Lens from Sigma mixes a comfortable focal length with an especially fast design. The bright f/1.4 maximum aperture helps to achieve shallow depth of field and selective focus effects, and also suits working in difficult lighting conditions. The optical layout incorporates both low dispersion and aspherical elements, which help to improve sharpness and clarity by controlling both spherical and chromatic aberrations. A floating elements system is also used to maintain performance throughout the focusing range. A Super Multi-Layer Coating is also featured, and helps to minimize flare and ghosting for greater contrast and color accuracy when working in strong lighting conditions.
