As a "hand-holder" photographer, I place a lot of value on high ISO image quality as a means to keep shutter speeds high. When I bought my D80 four years ago, I decided I would upgrade the body when advancements in sensor technology reached the point where I can get two additional stops of ISO speed, in other words, the same IQ at ISO 1600 that I get now at ISO 400. To measure this, I use the DXO sensor signal-to-noise ratio at 18% gray (SNR 18%).

From what I have read, it appeared the D90 fell short of this goal, and I was hoping the D7000 would do the trick. But when I look at the DXO SNR 18% graphs at this site, it looks like the D7000 also misses, delivering about 1.25 to 1.5 stops better than the D80 and just slightly better than the D90.

DXO Sensor Ratings

Am I correct to use these SNR 18% graphs to measure sensor high ISO image quality, and are my conclusions correct?

Thanks!
