with regards to the mentioned low lag time with the X100t, this is true if you are in manual focus (you can still auto focus with the back button). However I find the focus speed slightly annoying, say compared to my old 5D. If anything is moving you'll miss it. I'm seriously considering the X-T2 when it comes available as the focus speed looks promising. 

 

Agreed, if the subject moves, matters become difficult on the X20 as well.  You have to lock focus and the subject must not move towards or away from the camera.  Still the camera is best when I want to capture a facial expression (and extremely silent).

 

I would like an X200 with a 90 equivalent lens.  Not going to happen, I know.  The X-Pro2 is in the typical 0.05s delay range of fast SLR/mirrorless (5 times longer than the X100/X10/X20).
