FIXED with 3.01!
Sony a7siii 3.0 firmware update issue with RAW output. It seems we no loger have dual ISO while outputting RAW to Atomos Ninja recorders. Since the long awaited update, many come forward with different glitches but this one is MAJOR. Having no way to go under 640 ISO and 1600 ISo beeing the cleanest, the RAW recording from Sony a7siii is very limited. Hope they fix it soon.
