An especially sleek portrait-length prime, the 56mm f/1.4 DC DN is a part of Sigma’s recent series of lenses and is designed to be used with APS-C-format Sony E-mount mirrorless cameras. The lens is characterized by its bright f/1.4 maximum aperture, which suits working in difficult lighting conditions and also offers improved regulate over depth of field for isolating subjects and working with selective focal point techniques. The optical design utilizes two aspherical elements and one SLD element, which assist to reduce both spherical and chromatic aberrations for greater sharpness and clarity. A perfect multi-layer coating has also been applied to suppress flare and ghosting with a purpose to achieve more contrast and color accuracy when working in strong lighting conditions. Complementing the optics is a stepping AF motor, which suits both photo and video applications because of its quick, precise and near-silent performance.
