That's quite a lot. I don't find the raw files from *istD to lack much in dynamic range as it is, so an increase of just 2 stops would probably make me a very happy man. > However, that requires a linear intensity response from the sensor and the > same size of the steps.

That's understood. :-) I assume the CCD itself, or maybe its surroundig circuitry, has a theoretical maximum dynamic range as well. IIRC, this has been mentioned on PDML recently too, but, alas for my attention...:-( Since there are so many factors to limit the theoretical potential, I suppose there will be some increase with diminishing returns going on. -That expanding the colour depth to 16 bits doesn't pay back for the effort and cost, to put it in veeery general terms...
