The Sigma 65mm f/2 DG DN Contemporary Lens is a shot-tele/long-normal prime offering a unique field of view well-suited to portraiture and selective everyday shooting. Complementing the slightly long focal length is a bright f/2 design that helps to maintain a portable form factor while also contributing to low-light performance and depth of field control. Optically, this 65mm f/2 includes a pair of aspherical elements and one low dispersion element in its design to control a variety of aberrations and achieve notable sharpness and clarity.
