Can you find the "natural" (neutral gain) ISO of the sensor?


Define it, and I will find it.

Simply put, that region where the sensor needs only unity gain (analog
and digital).

For example:

....has the 7D noise lowest at ISO 200. This suggests that the unity
gain ISO is somewhere in the region of ISO 200 (though not exactly there).

Cheers,
