Then why is there more "visible" noise in the D4 images on Dpreview?

You don't seem to be able to tell what is "more" and
what is not.

I personally can't tell from those image if there is
more noise or not. All I can tell is that the images
are *clearly* not comparable by visual inspection. They
are not taken with exactly the same light, they are not
normalized to the same pixel dimensions

That is a B.S. tactic. "Normalized." Take a 500,000 pixel area from BOTH
cameras, the D3s is CLEANER. If you can't see it in the images, you are
blind.

Learn something about it before you spout off.

I can't see it in the images because it isn't there!
One is bigger than the other, so how do you compare?
One clearly has shadows/reflections that the other does
not have. How do you compare them? The one you say is
noisier clearly has more contrast than the other, how do
you compare them?

Well, in fact there *are* ways to make *valid*
comparisons. And when that is in fact done... the D4
images that have been seen so far are cleaner than D3S
images. The images also confirm what Nikon has said.

Your "take a 500,000 pixel area" idea is hilarious. The
simple fact is that if you take the best images you can
of a scene and then print them both at some large size
(the same size for images from both cameras)... that
will provide a useful visual test, and it will verify
what the scientific tests, on normalized images, are
showing.
