We will be shooting Blackmagic RAW because this is easy on our PC.Since this is common to both cameras, we will not account for this. We are recording audio via one XLR microphone.One zoom lens would be simpler than two primes, but low light is a concern so we have to account for that. We need two focal lengths, a 25mm and 50mm in the full frame equivalent.We can’t afford a focus puller or wireless system.
