Samyang

Samyang Optics is a South Korean manufacturer of photographic and cine lenses. Often marketed under the Rokinon brand, Samyang lenses can be found for most major lens mounts for mirrorless and DSLR cameras.

Unlike other lens manufacturers, Samyang focuses on full-frame prime lenses, though it had in the past also produced zoom lenses. It is one of the few companies that produce autofocus lenses for photographic cameras, with a strong focus on mirrorless.

Currently, Samyang's autofocus lenses cover focal ranges from ultra-wide to short telephoto, with Sony E-mount being the best served. Like other third-party lens makers, Samyang also has a large collection of manual focus lenses.
