Sony FE 50mm f/1.4 GM - Sony E-mount

The FE 50mm f/1.4 GM is a high-performance standard prime lens designed for Sony full-frame mirrorless cameras. It features two XA (extreme aspherical) elements and two XD linear motors, providing high resolution across the frame and silent, rapid autofocus. Despite its large f/1.4 aperture, the lens is notably compact and lightweight compared to previous iterations, making it suitable for both professional stills and video work. When purchasing a used example, inspect the front and rear glass for any marks or coating damage. SDS technicians check the XD linear motors for smooth operation and ensure the de-clickable aperture ring functions correctly across all stops. The weather-sealed gaskets are examined for integrity, and the lens is tested for centring to confirm optical alignment remains within factory tolerances.
