What's up with the obviously different contrast curve? How on earth do you lose hight detail in a piece of cloth with an A7rII? Why are most colours warmer in the Sony pictures? Why start comparison at an aperture where the 35mm camera will be disadvantaged by diffraction when you refuse to stop down the medium format camera to get an equivalent dof with the argument that it makes the image softer due to diffraction. Why talk about "a finger grain structure" on a fixed pixel pitch image sensor with 2.5 times the resolution?
All in all, if I wanted to rig a test in favour of the Hasselblad, I'd do something similar.
