Stylishly sleek, the Leica L-mount 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. A Super Multi-Layer Coating has also been applied, which reduces flare and ghosting for greater contrast. Benefitting handling, this lens features a stepping motor for quick and quiet AF performance that suits both photo and video applications. As an I Series lens, too, this lens incorporates a manual aperture ring and all-metal barrel constriction into its design for enhanced tactility. Additionally, there is a rounded nine-blade diaphragm for smooth bokeh quality and the lens housing is also weather-sealed to suit working in inclement conditions.
