The Sony FE 50mm f/1.8 Lens is a versatile full-frame E-mount prime that delivers exceptional brightness and sharpness in a lightweight, everyday-ready package. Its f/1.8 maximum aperture strikes the perfect balance between low-light performance, beautiful background separation, and a compact profile ideal for walkaround photography.
Built around a Double-Gauss optical design featuring one aspherical element, this Sony prime lens minimises astigmatism, field curvature, and coma for edge-to-edge image consistency. A silent DC autofocus motor and a 7-blade rounded diaphragm round out a lens that performs equally well for portraits, street photography, and video on any Sony full-frame or APS-C mirrorless camera.
