I seriously doubt the idea that one would always try to make a full-frame sensor "behave" like an APS-C sensor. Sure, if you want identical field of view and depth of field and overall exposure, sure, you mitigate some (some, probably not all) of the gains a better sensor has to offer. I seriously doubt such a scenario is very realistic, however. I currently use an APS-C size sensor, and while it is great for wildlife shots, when I move to a full-frame, I will do so because of the wider field of view, not to keep the same FOV/DOF. | |

But this results in a smaller depth of field, so you have to close down your aperture, resulting in longer exposures, so you have to up your ISO again to compensate for that. If you want keep the same look, that is. | |

You could have an 8mp sensor on both a full frame and an APS-C, and the full frame will have better noise performance because of the larger and less dense photosites. | |
