I have most of their primes, and most of their XF non pro zooms (no 18-135).
14 2.8 - sharp, light, little distortion
16 1.4 - sharp (borders need stopping down), nice bokeh combined with close focus, WR
23 1.4 - does everything well without being exceptional in any particular category
27 2.8 - sharp, very compact and light
35 1.4 - sharp (particularly in the center), can have awesome bokeh at times, slightly slower focusing
35 2 - good, WR, I'm less taken by it compared to others
56 1.2 - sharp, nice rendering, bokeh can be nice with a little care (avoid very busy backgrounds)
60 2.4 - sharp, macro, very light, takes its time to focus
90 2 - best of their primes, WR, misses stabilization (if you don't have the X-H1)
10-24 4 - very good and versatile, misses WR, sharpness is similar to other 16-35 equiv (very good till about 28-30 equiv)
18-55 2.8-4 - sharp, light and compact, misses WR
55-200 3.5-4.8 - sharper at the lower end, light for what it is, not the fastest focusing
