lets have a look at a video from guys who actually shot video.
enough boring talk from guys in this tread who know not much about video but talk like they have invented photography and videography.
just for a change...
Don't get me wrong, I love the look from the C500, but I was lost when they talked about reliability. it is incredibly annoying when the fan comes on during an interview setting, but experiencing the overheating warning and followed by an error makes it far from reliable IMHO. For reliable 4K professional video I think renting the F55 is still the way to go.
For affordable large sensor 4K cameras to own, the Blackmagic and the GH4 are my top choices. But I'll still need to rent a real camera until we have a few better solutions. I can't wait until we have CFast 2.0, it'll be nice to be able to record 4K at 23.976 and 29.97 fps 4K on a compact flash card and not have to worry about hooking up external recorders.
