I’m not a fan of the small Micro Four Thirds sensor size (yet I put my preorder in for the Blackmagic Pocket Cinema Camera 4K which is just that) but still the Panasonic DVX200 is quite the capable camera. Looking a couple of years back, this was and pretty much still is the cheapest fixed lens video camera that supports 4K60p. With a constant f/2.8 aperture throughout the zoom, you’d be very and I mean very hard pressed to find an interchangeable lens camera + 13x zoom lens combo at the $3.5K price point.
Here’s a quick rundown of the internal bitrates:
2160p59.94 = 18.75MB/s = 1.125GB/m = 67.5GB/h
1080p59.94 = 12.5MB/s = 0.75GB/m = 45GB/h
