Notice how comparatively blurry the canon pictures are? I suspect the canon had in-camera noise reduction on (whether or not it could be turned off) for the jpeg processing, whereas the Nikon doesn't look like it had NR enabled.
They state that NR was off on both cameras.
Yeah, are the colors wrong in the Canon? There's a huge difference as the ISO increases in the Canon.
Sure it looks pretty good, but that's really odd.
In any case, it looks like Canon did well with the higher pixels, but I'm still not liking the high ISO performance because of the weird color shifting.
You do get less intense colors the higher up you go with ISO. But I don't see as drastic of a change with the canon as I do with the color blue on the D5000. So I'm not sure what you're looking at NSX. The blue on the canon does fade out a bit but the color is still there. On the D5000 however the color blue disappears. Strange that it's just the blue and the other colors stay pretty much the same.
