This is a 50mm standard prime lens for Sony E-mount cameras, designed for full-frame use. It has a maximum aperture of f/1.8 and a circular seven-blade aperture, which produces a defocus effect in the background.
The optical design is a double-gauss configuration with an aspherical element. The double-gauss design suppresses field curvature and distortion, and the aspherical element controls spherical coma and distortion aberrations. A DC motor focus actuator system drives all lens groups for precise, fast and quiet focusing.
The lens has a metal mount for protection in challenging environments. It has a 0.14x magnification ratio, a minimum focusing distance of 1.48 feet and accepts 49mm filters.
