This honestly changes based on IRE scales of the camera. If your shooting C-log the middle gray may reside somewhere between 33-35 IRE for middle grey and it can be perfectly exposed. Same with SONY s-log 2; it is meant to be exposed at about 32 IRE for middle grey according to manufacturers , but tends to look better at 55-65 IRE on an 18% grey card. So when you expose with a spot meter whether it be a light meter or a camera spot meter, you have to account for exposure compensation. So for Sony it is classically said to expose 2 - 3 stops over. Each IRE value being 10-12 IRE per stop. So middle grey depends on the camera. Do tests and figure out where your camera sits vs where manufacturers place it. This is all based on log standards, however, if your camera keeps middle grey at 50 IRE as its standard, then this works fine.
Talked to a rep and engineer, they said MSRP is 6500 with the top handle and all. He said the raw upgrade will be free with firmware and will most likely be stuck at 10 bit. ISO he said will be native at 800 and the other native he estimated between 2500 and 3200. Also the raw is a form of compressed raw like Canon's new raw light
Unfortunately saw this at NAB. If you are more than 10 feet from the receiver the latency is horrible. The test they did has the receiver right next to the camera. You move 5 or 6 more feet and it becomes unusable. Save your money and get a Paralinx system. They are cheaper then Teradek and perform very closely.
They are using the same sensor, the biggest difference between the two is their capabilities with frame rates, cooling, use of raw at those frame rates, the fact that the Ursa has a few more physical features (like its massive screen), and an up-gradable sensor for the future.
They can't because then it would become a better camera than the 3000 dollar version of the Ursa Mini, image wise.
You are absolutely correct with what your saying. However, I believe in raw, the fs700 can produce about 13-14 stops of DR and having high frame rates with some moire is better than no high frame rates above 60fps. However, all that being said, each camera is a tool and each person chooses the tool that suites them.
