Ok, I should have said it provides the same amount of light per unit area of the sensor....surely???? Or are you saying that, for a given ISO ...

Not for given ISO. For ISO bumped up 1 stop (a little more actually), yes: the exposure time will be the same for Nikon 85/1.8 and Fuji 56/1.2. As would be the noise/detail ratio despite 1-stop ISO penalty, bigger sensors do perform better whatever Fuji marketing folks say (actually, more details under most conditions will be resolved by Canikon because of their higher pixel count, but that's another matter).

Full frame sensors seem to have about 1 stop less noise than APS-C sensors, and it really only becomes an issue in the real world (as opposed to the camera forum world where a millimeter is the same as a kilometer) at high ISOs above 1600 or perhaps 3200. Certainly in a situation where a person was shooting at more reasonable ISOs or in a studio at low ISO, it isn't going to make enough of a difference to care about.

I really wish people would stop trying to justify large sensor cameras based on the rather small advantages they have in a couple of parameters.
