I'm thinking about buying a Samyang/Rokinon 12mm, XF14mm, or maybe XF18mm so I could have a wide angle prime (the XF16mm f/1.4 is too big and too expensive for me) but maybe I should wait for Fuji to release a wide angle WR prime in f/2 (looking at what they did recently). Sadly the roadmap hasn't told us anything about this but I'm hoping. Do you think that something like this will come out in 2018? I'd like a 12mm f/2 WR but if it's too big and expensive then I could live with XF16mm f/2 or XF18mm f/2 Mk. II (the last two are most likely to come out I think).
