The Sony FE 50mm f/1.8 is a sleek and super portable normal-view lens that is ideally suited for every day street and travel photography. A double-gauss optical configuration reduces field curvature and distortions for more consistent image quality from edge-to-edge, which is a great feature for portraits and architecture. The DC actuator offers quick, quiet, and accurate AF performance for both still and video shooting. It is compatible with full frame (FE) E mount cameras and crop sensor NEX E mount cameras. Its effective focal length on a crop sensor is 75mm, which is great for short telephoto work and produces very pleasing headshot portraits.
