I thought DxO revenues came from DxO Optics Pro raw processing software and a series of specialzed film simultion plug ins. If I remember correctly the DxOMark web site is a means to promote the technical excellence of DxO Optics Pro.
The camera evaluations they publish are essentially derivative measurements thay already make for the R&D conducted in support of DxO Optics Pro. They also have data for lenses.
A few years ago I discovered that DxO Optics Pro outperformed ACR for the DSLR/lens combination I used professionally. In my case the improvements were not practical because my workflow demanded overnight image delivery. Speed and convenience are more important to my clients than a 5-10% improvement in IQ.
I am not motivated to defend DxO nor am I interested in annoying Leica owners. At the same time it is relevant to state that every single method DxO uses is completely documented in mathematical detail. I personally can't see how DxO's results are not objective.
While I usually detest automobile/camera analogies, all DxOMark's data measures is the signal-to-noise ratio of the sensor to raw file data flow. Of course S/N is critically related to dynamic range and bit depth. This is similar to only evaluating the overall performance of sports cars' drivetrains. Of course these tests don't completely characterize any camera or lens. They just objectively measure one critical component of the complicated mixture of objective and subjective factors that comprise the whole of the camera.
If I used digital Leica Ms, I would point of that careful optimization of exposure is typically more important than the technical potential of the camera's S/N. The large number of cameras with higher S/N than the Leica CCD sensors rarely function at their full potential because sub-optimal exposure is the norm Convenience trumps evaluation and thinking about exposure. In general photographers tend to place more faith in the camera automation than their own experience and ability to evaluate and optimize exposure.
Finally, DxO will soon test the new Leica CMOS sensor. Let's suppose this system has the best S/N of any camera evaluated by DxO. Does this mean these results would be silly, unimportant and unauthentic? Should camera buyers ignore those results too?
