I don't know about any parallax error about the X-Pro 2 but to me the X-Pro 1 was like a mixed experience, i bought it mainly for the OVF, image quality, the amazing fuji lenses and the "retro" controls/dials, at first didn't noticed any terrible parallax error, then i started to compose "in more critical situations" with my 35 1.4 and started to notice it was there, at first was kinda frustrating because i don't liked the idea of using the EVF, so i started to practice at different distances with the camera mounted into a tripod and i saw the error is only present at the bottom and the right side of the image, top and left line of the OVF frame are very precise in my experience, nothing really bad if you aren't extremely obsessive, i just got used to it so i know when im taking pictures that there is going to be a little bit more at bottom/right, so i recompose based on what i learned, not distracting, it just becomes second nature, sometimes i just crop the extra bit without any problems or regrets, i just use EVF when the subject is at one arm of distance or less and that is like the 5% of the time, the other 95% i'm enjoying the OVF. Important note!!! The OVF zooms in by default when i mount the XF35 1.4, i ALWAYS zoom out the OVF, that's maybe the reason why it is less precise to me, i just shoot that way because i like to see more context outside the frame, just to get more of the "rangefinderish experience" and that's the way i like it
