… And the "Print" results are inconsistent with the sensor output results. If it is "normalized" Dynamic range should not change or at a minimum the increase shift should be equal no matter the sensor size (MP) and should not show an exponential shift as it does.
people think that Nikon is spouting marketing bs to justify charging double for the D4.
The Dynamic Range @6400 (higher Ev indicates better noise handling)---Camera-----Ev Screen----Ev Print- D3s ------9.25 ------9.56- D4 ------9.21 ------9.73- D800 ------8.07 ------9.1This is the same with Tonal range and Color Sensitivity. That means when the "Normalization" happens, COLOR IS ADDED = IMAGE IS CHANGED = LOSS OF ORIGINAL IMAGE as colors (which result in details) are replaced. THAT IS NOT "NORMALIZING" DATA that is changing it.
PitchBlack: Actually, I have done so. I shot a full season of high school basketball in dimly lit gyms at ISO 3200 to ISO 6400, shutter speed around 1/400th second and f2.8. The D600 worked but the D800 was better due to two factors IMO: 1. The broader coverage of the AF area. and 2. The faster auto focusing. The D600 didn't fail to focus, it just took more time to do so. The D800 produced more keepers. But I wholeheartedly agree the D4 is the much better camera for low light action and would be the preferred choice over the Df. I do wish Nikon had put the D4 focusing module into the Df. Perhaps, a future version will get that module along with the Expeed 4 processor. Even then, the preferred choice for low light stop action shooting will be a D4. I do wish I could have one around for those few times I do such shooting. Most of the time I am shooing rather static subjects and desire the 24 or 26mp more than I desire blinding speed.
I just dug out my old Nikon FE2 to see how it felt in my hands. Honestly (and surprisingly), I didn't like it anymore! Why? Too small, too many sharp corners, insufficient hand grip for one handed carry. My conclusion is that the modern ergonomics are so vastly superior I don't want to use anything else. - See more at: http://forum.nikonrumors.com/discussion/1826/nikon-df-general-discussion/p10#sthash.tKQhzL7P.dpuf
