The RED Epic has a reflective surface around the OLPF that creates a Gate Flare. This is a flare that doesn’t come from a source somewhere inside the frame, but just outside. It’s an odd occurrence and according to some, used to happen on the Arri 235 and 435. Anyhow, Doug Underdaul from Long Valley Equipment, came up with a solution. Good read and very cheap, easy fix (if you don’t want those kind of flares).
