I use manual Nikkor lenses for 95% of the pictures I take. AF just annoys me more often then not, so it gets in my way.
A while ago I considered switching from my D3 to a Fuji X-Pro2 because the files it produced seriously impressed me. They also had the preferred 24 Mpix size, and the system as a whole would become somewhat smaller and lighter. Another great thing is the user interface. Rather then strange thumbwheels you get a real shutter speed dial, right there where it's supposed to be. Combined with a real aperture ring, like found on the Nikkor lenses, using those cameras would have been really intuitive for me.
I the end, having to rely on EVF did not work for me. If it does for you, the Fuji cameras are an awesome way to use a multitude of lenses, even some of the excellent Canon and Nikon rangefinder lenses. Those are the ones I miss most on my current camera solution, but I found out that for the time being, I can't photograph the way I desire without having a mirror and a pentaprism.
