In the high-ISO department, the X-Pro2 will perform at least 1 EV better than previous X-series cameras. Consequently, the X-Pro2’s Auto-ISO range has been expanded to cover 200-12800. Personally, I had no problems shooting as high as ISO 10000 or 12800. Even then, most of my samples were processed with minimized noise reduction settings. That’s because the camera’s noise is very fine (partly due to the increased sensor resolution) and looks much like film grain (thanks to X-Trans, there’s virtually no color noise, only “organic” luminance noise).
