Utilizing a "normal" field of view and a fast f/1.4 maximum aperture, the 50mm f/1.4 AS UMC Lens for Pentax K from Samyang is optimized for effective low light shooting, fast shutter speed capture and shallow depth of field control. When used on cameras with a ASP-C format sensor its 35mm focal length equivalence is 75mm.

The optical design of the lens consists of 9 elements in 6 groups including one hybrid aspherical element and one aspherical element to reduce chromatic aberrations. Also, lens elements are coated with an Ultra Multi-Coating to improve light transmission and minimize flare and ghosting. Eight diaphragm blades create a circular aperture for more attractive out-of-focus highlights.

As a manual focus and manual aperture lens, it provides a rubberized focus ring and clear aperture, distance and depth of field markings. Additionally, an included petal-shaped lens hood blocks unwanted light and protects the lens.

Standard length prime lens for full frame cameras, also compatible with APS-C cameras on which it has a 35mm focal length equivalence of 75mm
