Samyang AF 50mm f/1.4 AS UMC 50mm
Its bright f/1.4 aperture and 9-blade diaphragm produce smooth bokeh, while the optical design with 2 aspherical and 1 ED element delivers sharp images in a compact 420g build. A linear STM motor enables fast, silent autofocus for stills and video, and weather sealing adds reliability in harsh conditions. This lens suits Sony E-mount portrait photographers who need a lightweight, weather-resistant 50mm with quick AF and cinematic focus transitions.
