This past weekend I had the opportunity to shoot a short film on an Epic-M. We powered the camera off of Red bricks from the Red One. All we had for accessories was a Bartek follow focus. On nearly every take on our first scene, the camera stopped recording with a "Power Spike (C)" warning. The only option was to shut the camera down.
We tried rolling without the Bartek, which did not fix it. We tried all our batteries (we had 6) and they all produced the same effect. It seemed to get better when the batteries were more drained, and the error was more frequent the hotter the camera was, but it did it enough that we had to rent a different camera (not an Epic...) to finish out the shoot.
I talked to Red (thank you support staff) and they suggested that this particular camera body should be sent in to be checked out. Has anyone else encountered this issue? More specifically, has anyone had this happen with official Red bricks? I've heard this can happen with 3rd party batteries, but no one has posted anything about Red bricks causing any problems.
