Yesterday I was able to handle an X-T2 at Camera World, a shop off Oxford Street which I have used several times in the past.
I did not have long, but my immediate impressions were very favourable. It feels like an improved X-T1, with many things familiar but better. The joystick to move the focus point is indeed a joy, and pressing it in to the camera body centres the point. The EC dial is a little stiffer, which makes it harder to nudge accidentally. The ISO and shutter speed dials have a lock/unlock button, so you can lock a setting or have the dial moveable, as you wish. These dials are a little taller than on the X-T1, and easier to adjust without moving the drive and metering mode dials below. Focus seems much faster, and the camera more responsive, but I was not able to carry out a proper test.
The booster grip makes the camera noticeably heavier, but that does include two extra batteries. The grip fits well and is comfortable to hold.
The D pad buttons are slightly raised and easy to operate.
I pre-ordered camera and grip from Camera World, as they offered a very good deal on my old D300 and grip.
All in all, from my brief experience, I would say that Fuji has listened to its customers.
