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.
Cinematic images too if you know how to light - monstrinthedark.com
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.
Just shot a commercial on an a7s. My DP owns the camera and a Metabones Speedbooster, not the regular adapter. So all our shots are done in the APS-C crop mode which leads to less rolling shutter. We shot on Canon glass and had no issues. In fact, we shot for about 8 hours and only used two batteries, which seems contrary to everything i read about poor battery performance with the a7s.
