iRentals.cn (the Chinese equivalence of lensrentals.com) has just tested the GFX 50S. They have found that the GFX 50S + 63mm f/2.8 combo is a tad softer than the 5DSR + Otus 55mm f/1.4 combo, when both are shot at f/5.6 with the center cropped at 100%.
They also found that the dynamic range of GFX at pixel level is below D810, but would get a draw when down-sampled to 36MP. The high ISO performance of GFX can be about the same as D5 if down-sampled to 20MP.
However, due to the small aperture of the 63mm f/2.8 lens, under low light situations (hand-held without strobe) the GFX is even a bit weaker than its APSC sibling - XT20 + 35mm f/1.4 due to purple shadow. The degree of bokehliciousness (separation of main subject from background, aka diameter of circle of confusion) is also a bit weaker than the APSC.
Other findings include inflated ISO numbers for the GFX, but that's not as severe as Fuji's APSC cameras.
