Clearly, the photographer is very skilled. It is also clear that the X-H2s is good enough to keep up with such a difficult subject and not be an impediment to his work. I'm not a video user at all, so I would probably wait for something like the X-T5 and hope a lot of this capability is available in that body. I'll be curious how much of the AF can transfer to the bodies without the stacked sensor. I'm sure would not be alone in that thinking.
