Samyang is a Korean manufacturer of lenses that are designed to fit a number of mounts (including some DSLR mounts as well as many mirrorless mounts).
Samyang lenses are also licensed to others and may appear under a different brand name, so the exact same lens may appear under the Bower, Falcon, Rokinon, Pro-Optic, Vivitar, or Walimex name. In a few cases, a lens only appears under one of the other brand names as an exclusive, but is still made by Samyang.
