It has been confusing over the last few years understanding who is doing what after the image is captured. This article does a nice job of explaining it.
Matthew Duclos has touted the Rokinon Cine primes since they debuted. Now they have rehoused the lenses and branded them as Xeen Cinema Primes.

Sounds great, anyone want to buy my used Cine DS primes?
