I own the Rokinon 85mm f1.4. I bought it a year ago or so, since the Fuji 90mm wasn't available at that time.
Pro: distinctive look and feel of the image (if you like it)
Con: (1) it's huge and heavy, (2) colors need post processing, mostly too flat, less contrasty, and it stays that way even when stepped down, (3) chromatic abberation is quite obvious.
I would not especially recommend this lens, since Fuji has now better options available. The Rokinon gets the job done, but requires some skills, patience in post processing and will always be the heaviest lens in your bag.
