I don't know. I guess I'm not enough of a nerd, because this cam does absolutely nothing for me. The 4K thing is way down on my list of priorities. The no changeable lens thing, and abysmal low light performance disqualify it for me right out of the gate. Once you give me that kind of low-light, there is nothing to discuss any further. Goodbye. It's like saying, hey guys, this new sports car has Ferrari wheels... oh, and a Yugo engine. Pfft. And the hassle with multiple SD cards? Insane. I don't know what JVC is thinking, but I cannot imagine this is going to be a big seller for them. But then again, when was the last time they were relevant to indie filmmakers? I say indie, because that's whom I assume they are addressing themselves at that price point.
