Samyang 16mm F2 ED AS UMC CS
Specifications
The Samyang 16mm features some of Samyang’s latest optical technologies. The combination of hybrid-aspherical (H-ASP) and aspherical (AS) elements keep the image sharp from the center to the edge of the frame across its range of apertures. The proprietary Ultra Multi Coating (UMC) keeps flare and ghosting to a minimum and reproduces colors as true to life as possible. It is similar in style and performance to the Pentax SMC coating. A single extra low dispersion (ED) lens element reduces aberrations.
