It's also worth mentioning that, of the fuji lenses out there, this is one of the few that is kind of known for not being super-sharp in general ..... and you have quite a huge number of elements in motion here on top of that with lots of areas that would compete for focus ..... so like the guys above said, first things first, do an objective test of the camera and lens at the focal lengths and aperture that you're describing with everything else out of the picture to determine if your combination is going to produce what end result with every other variable accounted for.

If I have to choose 3 it would be the 14, 23 and 56 with an honorable mention for the 35 ....

Your hit rate with the X-T1 will be similar to what you're seeing with the D600 or better and at least as good as you are seeing with the D800(likely better) but not nearly as good as you would be doing if you were using the D810 you wouldn't be nearly as happy .... the fuji beats my 800 but can't even compare with the focus system in the D810.
