Honestly, I think people would be shocked with how well cameras much lower on the totem pole would look under those conditions. You never see it because no one spending that kind of money on talent, art direction, lighting, grip etc.. is gonna bother with a GH4.
But I'd love to see it. I'm quite convinced if you chucked a GH4 (or hell, a GH2) on a top grade hollywood lit set and hit record, people would be blown away.
Yep agree. You posted as I was posting but we basically are thinking alike.
