We have a Fujinon HA14x4.5BERM - EFP/ENG B4 2/3' lens and are interested in using it on an Epic, now that it will record 2K. Does anyone know if that is possible? I was just checking the Red store and noticed that the B4 to PL adapter only works with the Red One, not the Epic or Scarlet. Is this a mistake? It seems like it would work with all the cameras. Also, I think Red made some cables to give power and button on control to the EFP/ENG B4 Fujinon lenses. Does anyone know if the same cable will work with the Epic?
