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. However, I thought that Alexa fared worst in resolution than it probably should have (less than 2K measured), given that it is a 3.5K sensor (though with larger photosites), so perhaps there are some issues there to iron out. I’m sure there will be subsequent tests from others that can confirm or dispute these results, so we’ll see. For today, I’d like to concentrate on the dynamic range charts, which most DP’s are probably more interested in. Read on…
