On ENG cameras we have typically had controls for ND filters and controls for gain. Of course more ASA speed (higher gain) means more electronic grain.
Perhaps the M sensor, like SLR sensors can be adjusted for gain across a wide threshold?
If so then to quickly reduce exposure instead of an ND filter we could just reduce the gain to say -20 enriching the picture reducing gain and saving ourselves from an external filter in a matte box sort of change when going from indoors to outdoors for example. The changes in sensitivity could be both the gain settings usual to ENG cameras and also the little filter dial....
Our digital slr adjusts to 3200 gain at the other end more than equal to the Super gain of a SONY or PANASONIC news camera for getting that dark in the cave rescue shot
This has previously been discussed a little earlier (see above)with no real answer but not for the needs of ENG type shooters.
