Sigma 65mm F2 DG DN Contemporary in L-Mount is an all-metal I series prime with a 36.8 degree angle of view, a nine-blade rounded diaphragm and a body 72mm in diameter. Sigma says reduced vignetting limits lemon-shaped or swirly bokeh, and the supplied LH636-01 hood helps against backlit flare. The lens is discontinued.
