In what way? I have 5dmk3, XT1 and they both do same in studio. I saw your earlier about XT-2 no nailing AF in case of burnt out modeling light. I have same issue with 5dmk3, 85L when modeling light is off.
I didn't use my 85Lmk2. The 24-70L f/2.8mk2 nailed every single shot.
Maybe the fuji 55-200 isn't so great even when it's f/3.5 on the wide end of the lens.
