>>3959669The big advantage m43 in low light are lenses. You can shoot at f1.8 with near perfect corner sharpness, and very little vignetting. On everything larger, both will be severe, and you'll need to close down. Noise performance is about the same on base isos, at extended isos larger sensors start to get advantage.
>>3959473My own test from few days ago. It was shot for something else, so it's not exactly same settings test. Both are at 100% magnification. Isos aren't the same 1000iso vs 1250iso. Guess which one is larger sensor.
