Born and raised in LA. Passionate about all things video and film.
I absolutely love my GH4. It's got a ton of functionality with custom frame rates, low and high bitrates, and multiple resolutions. I've had zero issues with it in the six months I've owned it.
I've never shot with the BMPCC, but my friend who owns one says that the color grading process can be somewhat time consuming. If you like instant gratification and being able to deliver quickly, go with the GH4. Plus the lenses are pretty inexpensive and it takes great photos as well.
