A simple, bright, and lightweight normal-length prime, the FE 50mm f/1.8 from Sony is a versatile lens designed for full-frame E-mount mirrorless cameras. Blending a sleek stature with a versatile focal length, this 50mm prime excels in a variety of shooting situations and the f/1.8 maximum aperture helps straddle an ideal balance between brightness and a compact form factor.
 
Optical Design
One aspherical element is incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.
Double-gauss optical configuration helps to reduce field curvature and distortions for more consistent image quality from edge-to-edge.
