>>4074278The preamps are the same to cut cost. bigger pixels SHOULD give more room for a larger and cleaner preamp. preamp and adc. still, the larger microlenses will perform MUCH better, so you should see ultrawide lenses do better (not equivalent, but same mm).
in addition, the surface has thv, but this year Sony announced a way to maybe dedicate more of the surface to the "pixel" (light receiver photodiode or maybe new tech will come).
ALSO more waste in terms of the surface of the pixel.
PROOOOOOF
compare the high iso performance of the Z6 vs Z9
