Re: Nikon is the best in noise reduction. YES!

The balance between luminance and chrominance noise has nothing to do
with the sensor, unless a sensor has high levels of low-frequency
noise, and that is generally not the case in expensive cameras, whose
noise is generally concentrated near the nyquist.

The demosaicing algorithm used, and any subsequent software PP is the
only thing that makes noise lean towards luminance or chrominance in
these cameras.

Well, that was exactly my point.
