I also think these movies were shot before s-log. They all look like video. Where can I see good cinematic s-log footages with no sony look? Any links?
My standard recommendation is rather than looking for footage, rent the camera and an external recorder for a couple of days and see what you get from both internal and external recording. Grade the footage to your taste. That is the only way you can definitively assess the look.
