Continuing with more info on the Blackmagic Cinema Camera. We are going to look at some battery solutions for the camera. The current built in battery on the BMCC will get you roughly 90 minutes of battery life. Not much when shooting out in the field. However there are some other options. The camera will accept 12V-30V DC power.
