GH4 2 GH4's or buy a C100 to go with 1 GH4

I can verify that the bmpcc is not in the same league for low light as the other cameras being discussed in this thread.

I have the 17.5 f/0.95 and I also have other very fast primes. The problem is, shooting at f/1.4 all night isn't my idea of a good time. Maybe for stills, but not for video. It's nice to have the option, but it can be a pain to HAVE to shoot absolutely wide open. Sometimes it is an artistic decision to shoot with a deep depth of field, especially to show reactions in the background etc. Know what I mean?

I do know what you mean - as a matter of fact I am tired of super shallow depth of field video. mcbob mentioned 80k ISO(!?). That being the case I'd say if you can in fact shoot low light at f4 that would make life easy. One of the benefits of m4/3 to me is the deeper depth of field from the smaller sensor. Makes it easier to keep things in focus. Do let us know your results and good luck.
