In the measurements by Lenstips the Samyang actually beats the Canon:I can confirm that the Canon 135 f2 really doesn't autofocus in a useful way on any adapter I've tried (And according to others not on any other - I've tried MBIII and Fotga)
So it's effectively a manual focus 135. I'd buy the Rokinon ahead of it. But if, like me, you have a Canon 135 I'd keep it until a native AF option (Batis or Zony) comes out. Looking at Photozone the Canon and the Samyang/Rokinon are pretty similar, maybe the canon is even a tiny bit better wide open.
