They can charge whatever they want, there is no competition at all. Full frame is not the same as super 35 or Micro 4/3rds you can't compare products.
Saying they need to price against Sony is like saying the 1dx has to compete with the 7d price wise.
The Panasonic and Sony cameras get absolutely slaughtered in low light and I have little doubt this camera will continue the trend.
Although definite QQ no way I'm going to be able to afford that, I was hoping it would fall between the 5dIII and 1dx as well. No such luck.
If the Cinema 1d doesn't have clean HDMI out though, that's pretty brutal. Hopefully you don't need a additional recorder to capture 4k footage. They should just put SATA 3 connections on these 4k Cameras, consumer SSD are going to be vastly faster/high capacity than whatever they can come up with.
Those lens aren't going to be full frame I take it? Why are cinema lens typically zoom lens by the way?
