There was an old saying that a musician that I managed once used to toss around, and I've always liked it. "The clothes don't make the man" he used to say.
This saying can be modified slightly for filmmakers to read "The camera doesn't make the filmmaker". In other words, if you're a good story teller, it really shouldn't matter what you shoot your story with.
This has to be one of the best articles I've read yet on the state of current camera technology and image formats. Specifically, it covers the debate over raw/4k image capture vs other formats, why raw is great why it sucks and how at the end of the day, the camera doesn't make the filmmaker.
