Df Photographic Dynamic Range (PDR) - no surprise
2

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

Re: Df Photographic Dynamic Range (PDR) - no surprise

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

Not quite

: you use the nominal ISO values, correct?

Yes, the so called "manufacturer" ISO.

Re: Df Photographic Dynamic Range (PDR) - no surprise

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.
