ISO performance of D90 vs D7000

As far as IQ, dynamic range, and noise go, my answer to your specific question would be no. My answer would change if you plan to do a lot of shooting at ISO 3200, 6400, and higher.

I got one because I wanted the specific features the D7000 body offers over the D90. This includes more dials, faster flash sync, user setting banks, AF fine tune, a better interface, better video, and more fluff.
Having both, if you were buying one now would the D7K be worth $1,100 to the D90's $700? For me it's family pictures, etc. I currently have a D50.
 
that count, not the individual pixels. You demonstrated this well, my D90 brother. Pretty cool images to show your point. Thanks.

I'm currently recovering from the disease of pixel peeping-itis. In general, the better the IQ (i.e. the lower ISO value), the better I feel about the image. But I feel worse when I miss something that a higher ISO would help with. One of my first actions as pixel non-peeper is to up the max value of my auto-ISO to Hi1 (6400). I'll do what I can to minimize my ISO in a given situation, but, damn, I want to get those hard to get shots.
I like Greystar's statement (above post):

"That's not what the RAW data shows. The shadow detail is the same. What the D7000 has is a better processing engine. It also has other features that make it well worth the asking price...but better IQ at ISO 800/1600 is not one of them."

If I peep at the pixels, I can see a little difference (more detail) in the D7000 vs D90 images. But when I back off, I see no difference in IQ. I have a suspicion that sensor designers has reached a plateau with the performance they can wrestle from a given piece of silicon real estate with the current technology. They can capture light as well as they are going to. My belief is that D7000, in addition to all of it's cool new features, has advanced it's even higher ISO capabilities through clever firmware and a quicker micro controller.

All these conclusions suggest, however, that if I can't capture stunning images with the D90, then it's the finger on the shutter release that needs upgrading.
 
Wow you shoot only outdoors in bright sunlight or only stationary objects in low light.

Try shooting indoors sports or outdoor field sports at night!
Is it really that important that the ISO is a bit better on D7K above 3200? You never really are going to shoot at those types of ISO's unless you are testing cameras. Maybe 1% of photographers shoot above 1600 ISO on a full time basis. So really you should be comparing low ISO's. To the human eye there really isnt much difference

If I was buying a new DSLR and didn't have the D90, then I would probably get the D7000. But having the D90, I dont see the D7000 as a new technology jump. More pixels isn't always a good thing when you cram them together on the same sensor size? more features but also missing some features. I think that in about 1 year the D8000 is going to have new sensor technology and that will be worth the wait.
1.5 stops better DR, 33.3% more pixels. . . and a bunch of features including 100% viewfinder.

Had D90, sold it and bought D7k. Seems a LOT better. I only shoot raws, and the most striking difference is how much I'm able to lift shadows until I get unacceptable noise. I don't know about measurements and all, but using PP I get MUCH better results from high iso photos - concerts and such - than what I got from D90.
Overall, I'm very impressed.
 
The d7k suffers zero performance hits vs higher density. It improves on resolution, DR and high ISO over the D90. I agree a D90 owner should look very carefully to see if he needs the small IQ upgrade, but the pixel density still beats the D90 across the board. Kudos sony for a fine sensor.
