For me the biggest problem with the X-H2S is the manual focus experience on newer Fuji lenses (the only ones I have experience with). Manual focus on the 33 1.4 and 18 1.4 is unusable — huge jumps in between focus areas when set to linear focus. And since the autofocus isn't great (for anything other than a 1-person interview, where it does fine), you need good manual focus. And if I'm going to manual focus, I'd much rather shoot on my 6K Pro.
Also the image is way too sharp, even at -4. It's unflattering when you're shooting people, even with a 1/8 BPM. I'm a big Fuji fan and I'm not getting rid of my X-H2S because I like it for photos, but to make it usable for video I wish they'd fix the operation of their lenses, add touch tracking AF, and figure out sharpening.
That said, the dynamic range and rolling shutter is good. And I love all of the codec options + open gate. It's so close to being good, but these issues make me reach for my FX6/3 or Pocket 6K.
