From DXOMark: More pixels offsets noise3

you guys are once again making no sense

Arrg, I shouldn't step in . .

The effect of the microlenses is to change the sample from a discrete
sample to an averaged sample over the width of the pixel. This in
itself will reduce the very highest frequency response of the system,
another factor that oversampling can overcome.

The pixel averages the light whether you want it or to. Microlenses have nothing to do with sampling theory. A pixel resolves a pixel resolves a pixel. It's like saying that one bit records a certain amount of information, but filtering the data to one bit reduces the information. One bit records one bit records one bit . . .

Once more, even if the microlenses are substantially larger than the pixels there in no change in frequency response, except that more light is gathered, possible lowering noise.
