A larger sensor still gathers more light. My X100 with the lens set to f4 gathers a lot more light than my iPhone 5 with its lens wide open at f2.4. Sure, I'll have to raise my ISO on my X100 a stop and a half more than the iPhone to reach the same exposure, but my X100 at ISO 600 is still MUCH cleaner than my iPhone at ISO 200.
In other words, you have to think of equivalencies in terms of both depth of field and light, not solely depth of field, because larger sensors are inherently cleaner than smaller sensors (assuming somewhat like sensor technologies.)
So, using a 56/1.2 at ISO 200 on Fuji X will result in similar depth of field and noise characteristics as using an 85/1.8 on something like a D600 at ISO 400, give or take. ...Show more →
No it most certainly will not result in the same noise characteristics. When comparing the Fuji to the FF you will have to keep in mind that the Fuji has a different filter array that will reduce the noise at higher ISO (at the cost of some reduction in detail at low ISOs). So this sort of comparison goes completely out the window when comparing sensors that are quite a bit different. It of course also matter which FF camera we are talking about. I would not be surprised at all if the Fuji cameras have lower noise than an older FF camera like the Canon 1Ds. In fact, I am almost sure that they do. Large sensors are not inherently cleaner. They just tend to be cleaner. It does very much depend on the particular sensors you are comparing. Old FF sensors in fact can have more noise than many of the newer 1.5 crop sensors, and the Fuji sensors have a trick up their sleeve when light is lower that none of the FF sensors have. So, especially comparing with the Fuji the equivalence argument is broken. Or said another way your qualification, "assuming somewhat like sensor technologies," is an assumption we know we cannot make when comparing the Fuji sensors to any FF sensor. We know they are not similar technologies.
