I just got this from a source:
Hello there, so I’ve come across a small variety of interesting news regarding the new Panasonic full frame cameras from a few credible sources.
Tip #1, A few weeks ago I was on a location scout and started a conversation with a fellow. We began talking about the new Panasonic full frame camera and he informed me that he has a friend in Japan who is working on the full frame sensors they’re producing. He said that his friend told him they are designing them to be able to shoot raw video.
Tip #2, I received this past Monday at Adobe Max in LA where I’m currently workshopping. I went and spoke with one of the Panasonic reps at their booth where I asked the rep about the rumor of being able to shoot raw video. The older gentleman replied, “I can neither confirm nor deny that it will be able to shoot Raw”, and then he subtly, yet meaningfully winked at me in a rather guaranteeing fashion. He then freely offered more information to me by telling me that the 150 megapixel capabilities of their camera will actually be closer to 168MP. With that information, I suspect we will be seeing some great thing from Panasonic this next year.
I have to admit this is not the first time I got this rumor. So probably there is something solid behind it. Of course, you have to expect RAW video to be recorder externally on a special recorder and not internally. That I really can’t see happening any time soon.
