>>3980315>Apsc crop of 25mp will have larger noise when you enlarge it, but apsc sensor of 25mp will have the same exact noise performance as ff sensor of 25mp. No it will not. Top row of pic are FF and APS-C sensors with the same MP at the same tech level viewed at the same size/magnification. Which has more noise?
>This is valid for well lit lighting scenes. Larger sensor will retain better sensitivity that will translate into better low light performance.>MUH SENSITIVITY! MUH READ NOISE!No. High ISO shots are dominated by photon shot noise. Bottom row of pic is a FF sensor with older/inferior electronics resulting in higher read noise versus a better tech/lower read noise APS-C sensor, roughly the same resolution (26mp vs 24mp) at the same magnification. Which has more noise? Why, the FF has less noise. Why? Because the noise is mostly shot noise and the only way to reduce that is to collect more photons.
