No offense but I think its difficult to conclude much from this set of test images. Tests like this can be misleading if the focus has not been very carefully set because even when stopped down the apex of the focus can be seen when zoomed in to 100%. Furthermore, one of the bigger differences between 35mm format and MF is the more rapid transition from in focus to out of focus. You can't see that when shooting a flat surface, and if you just compare the one facet of images, sharpness, you can't know that the point you are comparing is at the apex of focus in all the shots.
I agree with the above, but one can check shadow noise by looking at the darkest neutral patch of the ColorChecker. Since some of the images are not white balanced, I split out the RGB channels in Photoshop for the D3x, M9, and HasH4D60 images and determined the means and standard deviations with the Photoshop histogram tool.
D3x
red channel: mean = 49.34 SD = 0.89
green channel: mean = 48.55, SD = 1.92
blue channel: mean = 47.96, SD = 1.27
M9
red channel: mean = 48.61, SD = 2.24
green channel: mean = 43.91, SD = 2.74
blue channel: 40.34, Sd = 3.16
Hasselblad H4D60
red channel: mean = 44.22, SD = 0.78
green channel: mean = 44.38, SD = 0.87
blue channel: mean = 44.32, SD = 0.73
The noise is considerably greater with the M9 than with the D3x. Owing to its large total sensor area, the Hasselblad has the least noise. These values are likely within what would be considered photographic DR.
