Fuji x-pro 1 af
In good light and good luck. I was just shooting yesterday with 18mm and it is not that focus was not fast, it gave-up half of the time on the first try...
I can not recognize your statement.... I have used X-Pro1 for 2 months now. Before that I had Sony Nex 5n and Sony Nex 7. Both slower than the X-Pro1.
Maybe some more practice!
