Since when was the A7SII a “prosumer” camera?
Utter poppycock! The colour science is just fine. I have used it to part shoot countless hours of high end broadcast documentaries. Anyone who says that needs to learn how to grade.
I am sorry but that’s ridiculous thing to say. Anyone who puts out footage that looks like you say needs to learn how to do basic colour grading.
MUCH better autofocus, 1080p 120p no crop, better dynamic range, better battery, full frame video looked great, s35 is apparently better but not tried it. That’s for video.
Stills, autofocus again is much better, eye AF is excellent, 10fps is really impressive, two slots including one for UHS ii cards, better 5 axis stabiliser, 1 stool cleaner with noise. This is now a fast stills camera. I was very impressed.
