Marianne's data and the D4's low ISO behavior
Mar 1, 2012

I think some may have overlooked what I find the most interesting info from Marianne's wonderful graphs posted here (which have reached 150 posts):

http://forums.dpreview.com/forums/read.asp?forum=1021&message=40756917

The ISO200 data indicates that the D4 behaves quite differently than the D3 and the D3s at base ISO:

Observe that the D4 curve, as the EV value goes down, starting at -2, stays flatter and actually more similar to the D800's than to the D3/D3s (use 12MP curves for reference). Eventually, the D800's curve stays flatter longer, from -4 and lower.

That means the shadows behavior of the D4 will be very close to the D800 down to -4EV, which should translate im much cleaner results, compared to D3/D3s, at low ISO. That will also translate in wider base ISO DR, something not many were expecting.

And we are looking at ISO200, the ISO 100 curves for D800 and D4 should be higher, pushing them even higher in terms of shadows/DR performance compared to D700/D3s.
