X-pro2 VS Nikon D3s 12800iso

12800 ISO, 1/80, F4 in same size:)

X-pro2:

D3s:

My first impressions :

+ Very nice colours

+ Low noise in high ISO for APS-C camera

+ Good DR

- AF is slower in low light with 56/1.2 than Pana GH4 with 42.5/1.2 and D3s with 85/1.4D and 85/1.8G

- Viewfinder is too small. It is hard to use this viewfinder for hard work and wedding photography
