Lens Overview — Samyang 85mm f/1.4

The Samyang 85mm f/1.4 AS IF UMC is a manual-focus prime lens built for full-frame camera systems, available across an impressively wide range of mounts including Canon EF, Nikon F, Sony E, Micro Four Thirds, Pentax K, Samsung NX, and Fujifilm X. With a maximum aperture of f/1.4, this lens is well-suited to shooting in lower light conditions and to achieving strong subject separation from the background. As a prime lens with an 85mm focal length, it sits in a range traditionally favored for portraiture and general-purpose shooting.

The lens is entirely manual focus, meaning there is no autofocus motor of any kind — a trade-off that keeps costs down but requires the shooter to be comfortable with manual operation. Image stabilization is not present, so steady technique or a stable shooting platform is important, particularly at the maximum aperture. The filter thread measures 72mm, which is a fairly common size for accessories.

Weighing in at 513g, it has a solid, substantial feel without being excessively heavy. The multi-mount availability makes it a versatile option for photographers who shoot across different camera systems.
