The main appeal of the X-Pro series is that you get a clear view optical finder like a rangefinder. For those of us who learned and continued to shoot with rangefinders (and rangefinder-like cameras such as the Hexar), the XPro series, along with Fuji'x X100x series, make it possible to shoot as with a rangefinder. This has nothing to do with film, it has to do with camera type. However, the X-Pro has the advantage that when you shoot with different lenses, you can switch to a digital finder (or use the screen) and get the standard through the lens view. This avoids the issue of accessory finders and tiny outlines in the center of the finder that wide and long lenses can cause.
