D80 vs D90 ISO comparison:

[ExplodingTaco]

So here we go, I tried to take them under the same light all at JPEG Fine, and Normal and Auto on all settings. 100% Crop Same lens

Also, I have come to hate the light meter in the D80 it is never consistent or reliable. You can see that pretty quick from the images bellow that the D90 did a better job of exposure. But the main things is WOW check out the ISO difference. Obviously some of this is just software but it is good enough for me. After shooting a bunch tonight I am satisfied to shoot the D90 @ ISO 3200 for web and 1600 for most prints of people indoor.

D90 On left @ISO 200, 1600, 3200, 6400

Cool shots! Yeah, I've used the D90 as high as 3200 a few times (I still try to avoid 6400). It gets pretty grainy, but the grain is very cool looking - more like film grain than any of the horrible noise you get with older DSLR's and P&S's.
