Earlier quoted context omitted.
Red cameras are overhyped, but picture quality is not the issue. It is very likely that what you describe is more due stylistic differences in lighting, color grading and editing than due to the camera itself — coming from someone who professionally had to match colors on films shot on multiple different cameras on more than one occasion. Reliability is the main reason why Red cameras are overhyped, but you get good…
ARRI also has their own "picture style", at least the ARRI Alexa. I remember seeing video on YT where the guy bought a really old ARRI Alexa that was used in Hollywood back in 05 or 06. When they showed some of the footage they took with it, it looked exactly like an mid-2000's big screen movie, I honestly didn't realize those movies even had a "look" until I saw his video.
Is this the video?
