PDR values for the Df are only slightly below the D4 and D4S.

Comparable to the D800/D800E at high ISO (ISO 800 and up).

I love how the D3s still makes the grade

Thanks, good job. Just one question, for the millionth time: you use the nominal ISO values, correct?

Not quite

Yes, the so called "manufacturer" ISO.

Thanks for doing this.  Interesting and useful.  On the current generation of cameras D600, D800, D800E, Df, D4. D4S things have clearly hit a wall beyond some subtle (although perhaps perceptible) differences.  Even so the difference between a D800 at ISO 25,600 and Df/D4/D4S/D3S is clearly visible, but it comes through characteristics other than DR and noise.  Color retention and grain quality become the differentiating factor and there probably isn't a good quantitative metric that captures that.

Yes and no. For example, there are ways of measuring pattern noise as opposed to overall noise; but developing an easy to use and  reproducible tests that normal users can perform is another matter.
