The 85mm is very nice, it's the best 85 I've used to date at least though I've not had many, the Nikon 85 1.8G and Canon 85 1.8 USM being the only serious ones I could compare to. It's better than both, easily. The only competition for Fuji is the 90F2 and from the comparisons I've seen since it's release, the Viltrox 85 stands up very well. it might not be quite as sharp, or quite as fast on the AF but after recent firmware updates it's close enough to save £300+ on. And that's Brand new Vs used, you don't often see the 90mm for less than 600 even used.
You can have the 85mm and either the 23 or 33mm for the price [if not less than] the 90mm alone. No brainer if ever there was one
