Don't forget that the image quality is not only the sensor, it's also the optics.
In theory, the resolution of a quad bayer sensor would be close to the resolution of a bayer sensor with the same number of pixels (the information of resolution is given by the luminance, the 2x2 binning in color does not affect a lot the resolution). But the problem is that with pixels of 0.8 micron only :
1/ you need an excellent lens
2/ at 2.8 you get diffraction
For that reason, the 48MP of the MA2 cannot beat the 20MP of the MP2.
The good point is that the chroma noise, which is the most annoying to process, is reduced by the binning. Actually you get a noise of 12MP with a resolution which is in between 12 and 48.
This is without take into account the performances of the lens (distorsion, vignetting, homogeneity of resolution)
It's like hifi, a good CD player is not useful if the loudspeakers are crappy |
