Re: "equivalent to" and exposure

25mm f/2.8 1/200 ISO 400 on mFT is equivalent to 50mm f/5.6 1/200 ISO 1600 on FF.

Completely agree but then what I see is that for the same "equivalent" scene, one has to use ISO1600 on the FF vs. ISO400 on the mFT. What about noise now? I would expect the mFT will have a cleaner image. Where is the FF advantage when user is constrained with achieving a given DOF with everything else being equal? Can you expand on that?

Thanks
