Sigma 35mm f/1.4 DG HSM Art Lens for Canon

Sigma 35mm f/1.4 DG HSM Art Lens for Canon. 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.
