Im curious which settings they used for raw on the 300s vs D90. Since the D300s has more raw tweaking ability, (compressed,uncompressed,compressed lossy, 14 or 12 bit, high iso noise.....) and the 90 has less, it would seem that we should be able to mimic the settings. Active D levels too
Anyone studied it more? I have been curious, but not devoted to it

They are different cameras, as simple as that. Different electronics, different options, different processing, different AF and different exposure. The D300s is simply a different camera made by the same manufacturer.

But that isnt the point of the "DXO Sensor test" . Its purpose is to exclude all paramentrics such as those and only be an indication of unprocessed sensor data. AF and processing have not part in that. ActiveD does however adjust the exposure in addition to processing hence my inclusion.
