I was using an X-Pro1 for my Leica M mount lenses until I could purchase a Leica digital. I finally purchased a Leica M10 digital body but was so dissatisfied with its performance that I returned it.
I have since replaced the X-Pro1 with an X-Pro2 and replaced my three Leica manual focus lenses with a Fuji auto focus APS-C equivalent. I replaced the 35mm f/1.4 with a 23mm f/1.4 Fujinon; the 21mm f/1.4 with a 16mm f/1.4 Fujinon, and the 90mm f/2 with a 56mm f/1.2 Fujinon. I was able to make the replacements for less than the cost of the one Leica M10 body.
