Re: Not exactly gone...

Luminance with the Sony 36MP sensor is sampled at 18MP (if we take the green pixels as exclusive for luminance sampling) with b + r channels getting 9MP apiece. The quattro offers 20MP in the luminance layer but only 5MP in the other 2. What effect does this have. And what effect does having the two lower layers at least partly co-located spatially have?
