Description — Samyang 50mm f/1.4
The Samyang 50mm f/1.4 AS UMC is a full-frame compatible prime lens with a 50mm focal length and a bright f/1.4 maximum aperture. It is available across four mount options — Canon EF, Nikon F, Sony E, and Micro Four Thirds — making it one of the more versatile manual-focus primes for photographers working across different systems. Weighing 535g, the lens has a reassuring build quality without adding excessive bulk to your kit.
All focus operation is manual, with no autofocus support, which suits deliberate shooting styles. The 77mm filter thread is a practical, widely compatible size for those already invested in a filter system. There is no image stabilization, so steady technique or a supported camera body is important when shooting at lower light levels.
As a standard-range prime, the 50mm focal length is well suited to portraiture, street photography, and documentary work across both full-frame and crop-sensor cameras in the supported mount families.
