Thanks to Andy E. of Andy E.'s Photo Blog I have full Nikon D4 Photographic Dynamic Range (PDR) and Read Noise data.
The PDR is higher than my estimate, while the read noise is lower. This implies a higher Full Well Capacity (FWC) than I had guessed.
Don't be surprised by the "lumpiness" of some of the data. The D4 does intermediate ISO values through a separate amplification and this leads to "jagged" results.
See the updated PDR chart and read noise chart

Thanks. Did you do the same evaluation for D800 already?

I have D800 and D800E data also.Did you do the same evaluation for D800 already?
But these are not complete data from production cameras.
Look for D800(e) and D800E(e) on the charts.
(e) stands for estimate

Dave,
The ideal lines are based on no read noise with the exception of photon noise.
It's unclear how close to ideal we will ever get.
