All shot raw, using same Voigtlander 40mm Ultron SL II @ f/5.6 F-Mount lens (6D via adapter). Processed in LR 4.4 all defaults except WB. Df file converted to look like a D4 so that it's readable by LR (via hack here). All downsampled to 8MP for comparison.

The full gallery of 100% crops and full 8MP images for ISO 3,200 through 102,400 can be found in the following link: Gallery. I'll try to make the raws available tomorrow.

Here are select 100% crops:

ISO 100, 5 stops underexposed and pushed +5EV in LR, 100% Crop #1

ISO 100, 5 stops underexposed and pushed +5EV in LR, 100% Crop #2

ISO 12,800, 100% Crop #1

ISO 12,800, 100% Crop #2

ISO 102,400, 100% Crop #1

ISO 102,400, 100% Crop #2

Is it me or does the Df appear to be cheating claimed ISO levels? The images look darker.
