This was literally my first outing with the X-H1 to try out its high frame rate HD video and autofocus capabilities. All footage shot in HD @ 100fps with Eterna profile.
I just had the kit zoom with me at the time with a variable ND filter on the front. The camera was set to continuous autofocus, no special settings, it did a pretty good job though you can see a couple of very brief jitters. All in all it felt responsive and better than my GH5.
The soundtrack was recorded using the Dreadbox Erebus and Nyx semi-modular analogue synthesizers.
I should mention that the camera was running original factory firmware. I understand a latest firmware update from Fujifilm addresses autofocus improvements amongst other things.
