Thanks for all of the help, everybody. To clarify a little bit, I understand that there are many elements that come together to achieve that "film" look, but I am primarily concerned with matters pertaining to a MFT sensor (and I've received a lot of feedback about that, so thank you); specifically aspects of that particular sensor type that need to be taken into consideration when crafting a particular filmic look, i.e. crop factor, GH4-specific native abnormalities in skin-tone, which lenses look best on a MFT sensor, etc.
Thanks very much, Guy. Very helpful.
