To all those dithering about a purchase of an X-T2, I would say having used one for a couple of days, it's a complete no-brainer. It really is like having a different camera.
Two things stand out:-
1) Speed, its a real step up on an X-T1 in just about everything, but most notably switch on, focus lock and writing to the card
2) ACROS - this is just amazing, its like having a new camera (I can see my self setting several different Acros custom settings), noise at high ISO is handled superbly, and using algorithms only available in the X-T2 and X-Pro2 (thats in-camera not in LR or any other film simulation) it creates film like images. For me I reckon it's going to cut down on a load of editing time, and I reckon that I will be using more JPEGs than I have previously. It really is quite superb.
To me, it's the step change in mirrorless that we all cried out for - Mirrorless has come of age.
