Sigma 16mm lens, mixing a comfortable wide-angle design with an ultra-fast maximum aperture, thisSigma 16mm f1.4 DC DN Contemporary Lens from Sigma is a 24mm-equivalent prime for APS-C-format Sony E-mount mirrorless cameras. Characterized by its bright f1.4 maximum aperture, this lens is adept at working in low-light conditions, and also affords increased control over depth of field for selective focus control. The Sigma 16mm optical design makes use of several low dispersion and aspherical glass elements to control color fringing and various aberrations in order to provide high sharpness and clarity throughout the aperture range. Individual elements also feature Sigmas Super Multi-Layer Coating to suppress flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions. Benefitting the optical assets, this Sigma 16mm lens also sports a stepping AF motor for quick, quiet, and smooth focusing performance that suits both still photography as well as video applications. Additionally, a weather-sealed, durable construction enables this 16mm f1.4 to excel in inclement weather conditions.
