An FF sensor caches the same light at equivalent settings. Old FF sensors are noisier at higher ISOs than new FF sensors.
Again, how noisy a sensor is has nothing at all to do with lens equivalence. Lens equivalence is about how DOF and FOV translate from format to format. And if one for whatever reason looks for catching the same amount of light/similar exposure time, use equivalent ISO settings. That is all.
Not about noise in images, not about bokeh rendering, not about how sharp a particular lens is, or how soft, not about astigmatism or coma or other lens aberrations.
