Viltrox AF 50/1.4 FE

The Viltrox AF 50/1.4 FE is a full-frame lens with a constant aperture, designed for Sony E-mount lenses.

This lens has a focal length of 50 mm and a low aperture of F 1.4. Focusing is provided by a VCM mechanism – the silent VCM motor can precisely control movement and provides smooth and accurate focusing. The optical design consists of 15 elements in 11 groups, including 3 ED elements, 8 high-refractive-index elements, and one ultra-precision aspherical element. The front element features a high-quality HD nano multi-layer anti-reflective coating that is water-resistant and fingerprint-resistant.

The lens features an electronic aperture, internal focusing, and a constant length. It is compatible with a standard 77mm filter and is dust and water resistant. The USB-C interface allows for easy firmware updates.
