Samyang 50mm f/1.4 AS UMC Lens

My Product Code: 7480

Samyang’s 50mm F1.4 AS UMC is a fast-aperture, manual focus photo lens designed for full frame image sensors as well as APS-C and smaller sensors. The low F number allows precise control of depth of field as well as the ability to shoot in relatively dark environments. The lens features 9 lens elements in 6 groups including 1 glass aspherical lens (ASP), and 1 hybrid aspherical lens (H-ASP) to offer outstandingly high resolution. In particular, the H-ASP minimizes colour aberration to realise exceptional image quality and high contrast for centre to edge of every image, even when the aperture is fully opened. Samyang’s Ultra Multi Coating (UMC) technology optimises the light transmission and minimises flare and ghosting. There are 8 rounded aperture blades which produce pleasing bokeh. The lens body is compact and solid, being made of high-strength aluminium alloy.
