Hello Hansen,
if I was out on the search for a reasonable priced X-Mount camera with a prime for universal use, I'd go for a X-E2 with a 23/2 or 35/2.
The X-E2 has the same first generation sensor like the X-T1, which is a really nice sensor and is built top quality. I still love my X-Pro1 (besides my X-Pro2).
The new primes are fantastic. Sold my 35/1.4 when I got the 35/2, which is sharp AND fast. If you like it a bit wider, you'll prefer the 23/2 (even better than the 35/2, but a bit more expensive), which I love!
