Sony FE 50mm f/1.4 GM Lens (Sony E)

Sony FE 50mm f/1.4 GM Lens
Flagship G Master Normal Prime – Bright f/1.4 Aperture, Dual XD Linear Motors, 11-Blade Iris & Compact Weather-Sealed Design

The Sony FE 50mm f/1.4 GM is a high-performance G Master standard prime lens engineered for full-frame Sony E-mount camera bodies. Combining supreme optical resolution, creamy background bokeh, and fast autofocus in a lightweight 18 oz frame, this versatile 50mm lens provides a natural field of view suited for portraiture, street photography, commercial shoots, and videography. Its bright f/1.4 maximum aperture excels in low-light environments while offering precise shallow depth-of-field control for distinct subject isolation.

The advanced optical design features two Extreme Aspherical (XA) elements and one Extra-Low Dispersion (ED) glass element to virtually eliminate spherical/chromatic aberrations, distortion, and color fringing. Applied Nano AR Coating II suppresses internal reflections to prevent ghosting and flare in backlit conditions. Driven by dual XD Linear Motors, the lens delivers fast, quiet, and accurate autofocus with responsive subject tracking for both stills and video. Outfitted with video-centric features—including a de-clickably engraved aperture ring, an iris lock switch, two customizable focus hold buttons, and Linear Response MF—this prime is sealed against dust and moisture for field operation.
