Hi everyone,
I'm using the XF 23mm f/1.4 and 56mm f/1.2 on my X-T1 on various situations since 1.5 year now and I'm very happy with those lenses.
I'm planning to get wider with the XF 16mm f/1.4 later this year for the situations where the 23 is not wide enough and where I can move farther from my subject
If Fuji has proposed a fast (lets say 2.8) 10mm prime lens, I would buy that one as a fourth lens.
I have to say I hate mounting zoom lenses on my fuji system. I prefer primes, they're much lighter.
For zooms I (still?) rely on my reflex camera.
Hope this helps...
