Re: 1" sensor versus APS-C

This is the end of the road for me. I have said all there is to be said. What it comes down to is that you either do not understand or do not accept when I tell you, and referred you to the exposure vs brightness article, that exposure is all about how much light the sensor receives. when two sensors receive the same amount of overall light, provided they are of the same efficiency, they will generate more or less the same image, even if it means light is more concentrated on the smaller sensor. ISO on the other hand is a standard for output brightness, it is not part of exposure itself. Until you get that through your head you not be unstuck.

Good luck.

The fact is that you are wrong because you assume that you can always make up 3 stops of sensitivity on your FX sensor vs the CX sensor. That's not true even with the v2 vs D600 without post processing. If the v3 gets a backlit sensor and gains a stop or two sensitivity that won't even be true against the "same gen" 2013 D4.

Any gain you apply can be equally applied to both sensors and there isn't always 9 dB difference in their native sensitivity. This native sensitivity difference matters most not when both sensors have strong signals to work with (plenty of light) but when the signal is weak (very little light).
