Pick the Rokinon 12mm f/2 if you need an ultra-wide prime for landscapes, architecture, or tight interiors and can work with its f/2 aperture. Choose the Samyang 85mm f/1.8 if shallow depth-of-field portraits or low-light telephoto shots are your priority and you prefer the brighter f/1.8 aperture. Both share the same price, so the decision hinges solely on focal length and aperture needs. Neither holds an advantage in cost or build specs from the provided data.
