My initial impression is that the colour response looks somehow strange to my eyes. As for the "superior" image resolution, I just can't see any big difference against the other 16-18MP APS-C cameras here. I do see some optical imperfection, though. So, once again, I think the lens is the bottle neck for higher resolution, but not the sensor! Furthermore, I have to say that "a new APS-C sensor approaching full frame IQ" is just a marketing BS after all. Well, could the DoF (Depth of Field) be changed with the same *APS-C sized* sensor? And can the diffraction limit be ignored/overridden??
Update: 1001 Noisy Cameras write that the samples can be found at Fuji's own official website and there are a total of nine of the complete set:-
