The answer is yes. Rokinon and Samyang are two brand names for the same line of lenses manufactured by South Korea’s Samyang Optics Co., Ltd. Both brands offer a variety of manual focus, prime and zoom lenses for SLR cameras with various mounts including Canon EF, Nikon F, Sony A, Pentax K-mounts, MFT (Micro Four Thirds) systems and more. The lens designs are identical across both brands; however the physical construction may vary slightly depending on the mount type used. While prices may also differ between Rokinon and Samyang lenses due to variations in distributor pricing strategies or additional features like lens hoods or carrying cases that come included with some models, you can generally expect similar performance when comparing comparable lenses from either brand name.
