Samyang 50mm f/1.4 Overview
Utilizing a "normal" field of view and a fast f/1.4 maximum aperture, the 50mm f/1.4 AS UMC Lens for Sony E from Samyang is optimized for effective low light shooting, fast shutter speed capture and shallow depth of field control. It is compatible with full frame cameras and when used on cameras with an APS-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 shape lens hood blocks unwanted light and protects the lens.
