Got a local connection on a good deal on the Canon lens. Already have the Fringer pro 2. I have the Fuji 50-140 so I'd be selling that if I got the 70-200. I'd imagine that the Canon is either equal or superior optically but my big wonder is with regards to AF performance. Anyone using that lens care to offer some feedback and possibly an image or two?

I have not used that lens on a Fuji body but I did use it for several years on Canon crop bodies.  I much prefer the XF 50-140mm.  Optics are great on the Canon lens, but I never liked the focal length on crop.  For me, it was a weird middle ground.  Too long for a portrait zoom or event shooting.  Not long enough for sports and wildlife.Your needs are likely different from mine, but I would not consider the 70-200 a direct alternative to the 50-140. The size and weight differences between these two lenses are also pretty dramatic.
