Jim Jannard has posted some test charts shot by RED, comparing ARRI Alexa with the Red Epic MX. Given that Epic is currently in development as a prototype, it’s not a shocker that RED is the first to do any actual chart tests with Epic. The two tests were Dynamic Range and Resolution. On the resolution charts, RED bettered Alexa. That’s not that surprising, given RED’s historical fixation with resolution and that Epic has a 5K sensor.
