Viewing the hacked footage, the only complaint I have left is that the camera appears to perform some sort of spatial filtering (presumably for NR purposes) in dark areas. The noise in the midtones and brighter areas is fine and high-frequency, and almost film-grain like. However, shadow noise appears to be spatially filtered, with fine details missing. This occurs even with all the NR settings disabled on the camera, and is problematic for doing further NR in post production, especially when underexposed footage needs to be brightened.

Is this something you're aware of? Can it be disabled to give us a "warts and all" image from the camera?
