Well, thats is a good news - you can shoot now Cineform in 4K. It was impossible in preview firmware. It started to record for 4 seconds and than stopped. EDIT - It's not true. You can't. You can shoot Cineform for 10 sec and than you get FLUSH instead of REC and it stops.
CinemaDNG & KRW was transcoded to Cineform RAW by Kinestation.
One frame of CinemaDNG is 13.3MB vs one frame of KRW - 3.8MB. Honestly I cannot see differences between these three codecs. Maybe you can when you add tones of effects. DNG will handle it better.
I also checked new LUT's - v.09 neutral & dslr. And I play with my settings.
