Combining a comfortable wide-angle design with an ultra-fast maximum aperture, the 16mm f/1.4 DC DN is part of Sigma‘s Contemporary series of lenses and designed for use with Canon RF-mount mirrorless cameras. Characterized by its bright f/1.4 maximum aperture, this lens is adept at working in low-light conditions and increases control over depth of field. The optical design makes use of several low dispersion and aspherical elements, which control color fringing and various aberrations. Individual elements also feature a super multilayered coating to suppress flare and ghosting for greater contrast and color fidelity. Benefitting the optical assets, this lens also sports a stepping AF motor for quick, quiet, and smooth focusing performance that suits both still photography as well as video applications.
