Just been looking on
mpb and they have an xe2 and a 35mm 1.4 and 2 56mm 1.2..someone did suggest I went for the 60mm 2.4 instead of the 56mm but had heard it was a fairly slow focusing lens?
In low light, and on a XP1 the 60 is positively glacial, I'm talking seconds here, not hundredth seconds, but full on seconds
On my XT1 it's quite a lot more spirited! (If it's in the PDAF part of the sensor)
In good light, the 60 is really not terrible on the xp1
Although apparently better (I've never owned it) the 56 is NOT renowned as a fast focusing lens... (But better than the 60)
The XF60 is very sharp though and offers 1:2 macro, which can be handy, also (according to Fujivsfuji iirc) the 60 goes to a higher aperture before diffraction sets in, I seem to recall F11 vs F8 (on the 56), but of course the 60 doesn't open up to 1.2
I'm a bit of a shallow DOF junkie... And have pondered the 56 many (many) times but as a 60 owner, it's been hard to justify, and FWIW I'm more of a wide shooter (xf18 and by far xf35 being my used XF lenses. Obv YMMV) there's a rumour of a 35 F1.0 that I'm excited by...
The trouble with answering questions about AF is it's fairly objective and subject dependant, one persons 'not bad' is another persons intolerable!
Going back to your original question, can you not get somewhere to 'touchy feel' the xe2 and xp1? IMO the feel of the camera is so important to my desire to own it.
