Few more things. Tried the autofocus, both single and continuous. Test: kids playing in the mall, not great lighting, so a difficult one.
Result: overrated autofocus performance.
Now granted I might not have used at its best but even so, it's not a fast focusing camera. Maybe if you have the subject a little farther with more time to guide your actions it will be better. On single shot I can't say it was better than my X-E1 either. Once I get to know it better it could become.
Contrary to what I've heard the 35 was many times faster than the 18-55 which could be that something was not right.
These I can deal with it. What did annoy me was focus accuracy. It was faster many times with face detection on but still was missing more often than expected. On the 35mm I could expect misses as I shot wide at 1.4, but it shouldn't be on the 18-55. If you really want to have a higher keeper rate for kids this doesn't seem to be the one. Also because the focus was subpar I had a distinct feeling of shutter lag,
I did not have the high performance ON at that time.
Even with these shortcomings (apparent at least) it's still a nice camera. The JPEGs are really good. No access to raw yet. It remains a good camera for what I got it: a lighter higher quality image producer that's easier to take with me, for random things or travel, which has a decent resistance to the elements.
As my Nikon is a D90 the Fuji is my best pixel level camera also, but any current Nikon I could buy (D7100, D610, D800) will be better at pixel level and if you print big, or probably for not missing the moment with kids.
