[QUOTE="J-see, post: 459435, member: 31330"] If I check the SNR across the ISO range, the signal is close to identical when it comes to noise. There is about 1dB difference at lowest ISO while the rest is almost a perfect match. The main difference is not the sensor itself but what happens afterwards during A/D conversion and amplification. It's a cleaner result of a similar signal. For it to be a stop better at ISO, it should have the same dB at a certain ISO as the D7100 at its next stop. It doesn't. [/QUOTE]
