At a Glance

Built for APS-C cameras on L-Mount, this 50 mm lens reaches an f/1.2 maximum aperture. It corresponds to 75 mm in full-frame terms, so the view is that of a short telephoto. Focusing is manual only. The large opening shortens shutter times in dim light and allows a shallow depth of field. At 336 g, it suits portraits above all.
