I can't agree absolutely what you say; we works better when we now them limit and the best setting, it's the same with lens.
today I can say this evo 6k works not bad with this setting in LOG mode:
H265, 4k, 24fps to 30fps, aperture between 3.5 to 8, the best is f4, AWB manuel 4500, ISO 100 to 400, ISO 100 is the best, sharpens -2, contrast -1 saturation -1
like that post production is really easy and fast.
but there's a big probleme autofocus is terrible, really ! he work slowly and pumping a lot.
impossible to make proxy under 1 meter.
not so good this 6k.
