I just decided to look it up. I always remembered it as 12 for Raw photo. I remember Matt sheepishly introducing it as 11'ish for video. With a grin on his face.Well where did I get the 11.3 from? Must have been the GH2... sorry 'bout that. If the GH4 can deliver a full 12+ stops of dynamic range then yes that eliminates the concern I'd raised earlier (which I'll now go edit out and delete, as we don't want inaccurate info out there).
