When I looked at the image on a monitor it was very clean. It had excellent detail and in S-Log2 there was certainly a lot of information in the shadows and highlights. There was some noise in the shadows but nothing excessive. Sony haven’t published the dynamic range of the sensor but I expect it to be very similar to the a7S. I would be surprised if anyone could tell this image apart from that of a FS7 or FS700 shooting 4K without careful examination. It is that good.
