Isn't the Cion a PL mount camera? The Rokinon Cine DS line is not made in a PL mount. You may need some new lenses.
I've been shooting with the C100 Mark II since December and I love it. I'm on corporate gigs 5 days a week. Nobody is asking me for 4K delivery. Mark II AVCHD is nice, small file size, easy to work with. C-Log is great. It's out of my box and rigged with lens and audio in under a minute.

Why not have get a Ninja 2 or Ninja Blade for ProRes?
Seriously? You must be joking.
Could not agree more. New camera comes out and everyone posts a "test" video. Enough with the tests! Shoot something I want to watch. Your dog in slow motion sucks.
I sold my old 5d3 for a GH4. You'd just be going backwards. Not sure why you would need to switch to full frame though, unless you were really having trouble achieving shallow depth of field with your GH4.
