Actually you're right, enlarging to 300% view I can see a faint noise. But seriously I would love to know which camera does better? My K10D sure had noisy skies visible at 100%. But nothing that slight NR couldn't remove anyway. I can recall the D300 being also criticized for noisy blue skies. As I understand blue is always the noisiest channel, surely why high-ISO under tungsten is always noisier than in daylight.
P.S. I agree with others that your avatar is just tasteless.
