The Sony FE 50mm F1.8 is a compact, lightweight 50mm prime lens for full-frame E-mount cameras. Its maximum aperture is f/1.8, and a 7-blade circular aperture gives smooth, defocused backgrounds. The wide aperture also helps when shooting night scenes or dimly lit interiors. Used with an α series body that has in-body image stabilization, it allows handheld shooting in dark scenes without very high ISO settings.
The optical design uses 6 elements in 5 groups. A double-gauss configuration suppresses field curvature and distortion. An aspherical element controls spherical aberration and coma, and the design also minimizes chromatic aberration. The lens has a metal mount.
Autofocus is driven by a DC motor focus actuator system that moves all lens groups and runs quietly. The lens uses internal focusing and is not weather sealed. A lens hood is included.
