Ray, that is not correct. You have to look at the full SNR graphs. They have a wealth of data if you know how to read them. Emil gives a good introduction. I think I have posted on this before.
Ah! I see! You are quite right Bill. There is another heading for more detail, including the color sensitivity rating of each individual primary.
But as far as I can tell, there's no easy method of comparing different sensors when viewing the more detailed information in that lower heading.
Not being as technically minded as you, I'm more concerned with the relative performance of cameras, so the 'Compare Sensors' page, with the headings as I described, provides sufficient information to help me to make a decision. I'm not sure I need to know that the additional color sensitivity of a particular camera applies more to the blue channel than the red channel, especially if the over all differences in color sensitivity are in the order of 1 bit and less.
Most of us experienced guys know what the performance parameters are that matter the most to us. For me, the main concerns are lens quality, sensor resolution, high ISO performance, and dynamic range (within a reasonable price range that represents good value). SNR, tonal range & color sensitivity are generally so close that they are not an issue, comparing models of similar format.
I consider DXOMark a valuable tool only after one has sorted out the type of camera one would like, of the size and weight with which one is comfortable, in the price range which is acecptable, after considering the range of lenses and features one finds, or is likely to find, most useful.
Sometimes a purchasing decision can be difficult because competing camera models are often so close in performance. A slight advantage in one area is so often offset by a slight disadvantage in another area. But occasionally, a particular model of camera stands out from its competitors in one particular performance parameter that one might value.
Such was the case with Nikon D7000 for me. At its base ISO of 100, this camera has even better performance than the full frame D700 at its
base ISO of 200. Not better in every parameter, of course, but at least as good
in every parameter and significantly better in one parameter, namely DR which is 1 & 2/3rds EV better at equal print sizes. What a remarkable achievement!
However, at ISOs higher than 200, the D700 begins to show an advantage over the cropped-format D7000; and that's useful to know.
