I'm not necessarily against the film-camera-like control system for the shutter-, ISO- and exposure compensation dials or aperture rings on the lenses. They are handy because you can see the settings without pushing the function buttons or even switching the camera on.
What I don't like about Fujifilm is their "make-believe" film camera design concept. I picked up X-E3 at first because it looked least like a film camera in their lineup and switched to X-T3 for the excellent AF system. The co-existence of the dedicated dial system from the film cameras and the assignable system of buttons/command dials makes the overall user interface cluttered and superfluous.
Sigma fp is not a camera perfectly comparable to the established DSLR or mirrorless cameras of other makes, but it works well enough for my shooting style, and I really love its stripped-down design. The placements and assignments of the control buttons and dials are a bit unique, but it is well worth trying to get used to.
