Just downloaded the Blackmagic Design camera app, and I have to say I'll never again miss Filmic Pro, which is now subscription only. I don't immediately see how to record in any kind of LOG color scheme, but since the app does allow ProRes 422 10 bit recording, I suppose it's just a matter of importing a LUT that goes from Rec.709 to something like Sony Slog, or Arri, or.... I'll be playing with this in the coming days and will post my results. I once again applaud Blackmagic.
