Credit where credit’s due, the latest firmware fixes this and adds a dial toggle button option if you have the lens aperture ring disabled, so you can still easily adjust ISO, and all without jumping into that annoying ISO menu. Really pleased with this update. 

Yes I tried one a couple of days ago and was blown away by the video, which needed very little in Davinci Studio to look damn good. The images too are great and the camera grip is excellent. I have one to pick up in a few days.

He’s wrong about all of it and I seriously doubt he used the camera.  
 
I had the X-T3, sold it for the X-T4, and 2 years later I preordered the X-H2s.  I have had it since launch and here’s a quick rebuttals to that garbage review.
 
First, the people he spoke about, saying they backed up his claims…
Casey from Camera Conspiracies, only tried the pre-release and has since taken one on loan… He loves the thing now.
Gerald from Gerald Undone, said the camera’s DR is excellent, Still image capture AF is awesome, and he said thanks to the noise properties he can actually make the video better quality than the A1 (that’s impressive).
DPReview, said they wouldn’t rank the camera or comment on most aspects until they got a full retail version of it and that review is happening now.  
 
Second, he ignored the stacked sensor and the improved AF speed completely.  Then he made assumptions based on his ignorance of the camera and how it functions.  He claimed they didn’t think the design through, but his own complaints show he didn’t think it through.
 
I had the X-T4 sitting right beside the new body for about a week… The build quality was very much on par with the X-T4 and yet he praised one while panning the other.  So which is it, is the build quality of the X-T4 cheap, or is the X-H2S actually decent build quality.
 
Then of course he tried to equate knowing the X-T4 with knowing this camera and I can tell you they could not be further apart in the way they operate and still be a Fuji body.  
 
Many of us have action photos, portraits, BIF, and animal portraits, yet he seems to proclaim it is the worst camera ever. 
 
Of course he focused on 1 thing obsessively, that’s the fact that the dials don’t have any push button capabilities. Then he also made a comment that gave away his motivation for the whole review away… Fuji wouldn’t give him a body to review, so he rented or purchased one and panned the whole camera.  
 
Oh and as for Muddy images… I set both the X-H2S and the X-T4 to the same settings and swapped the lenses from body to body.  The image quality was pretty much identical, so you can ignore that garbage claim too.

I struggle to get past the early part of the review.
He comments very negatively that the Manual-Single-Continuous focusing switch of previous cameras has been replaced by a button and popup menu, due to cost saving.
Such switches will not work with the new C1-C7 custom settings, If you set C1 to Continuous and C2 To single, how would the mechanical switch update as you change from C1 to C2?
If I can figure this out and a professional reviewer does not I find it hard to trust their opinions.
 

sorry, but the guy is either crazy, or an ignoramous, or both and just wants your clicks. I happen to own two X-H1s and the new X-H2s, and there is not a single point where the new model isn't superior to its official predecessor. And regarding IQ: At least the high-ISO JPGs are definitely better. But Fuji never promised such and already said before their press-event on May 31 that regarding IQ there would only be minor improvements.
cheers, CF

I don't understand the big deal about this - ISO can be assigned to the dpad - press up and ISO goes up - press down and ISO goes down - it shows in the EVF but it doesn't fill the EVF and disappears as soon as the change has been made.

Hmmmm.  What is your shooting mode?  Maybe a dumb question, but did you somehow turn on the ADV. Filters mode?  The vignette almost looks like how the "Toy Camera" mode looks.

I found the cause. Advanced filter. Thanks you so much!

Here's a list of firmware requests for the X-H2 / X-H2s I've either had myself or collected from videos/reviews. Feel free to add more or disagree/agree in comments!
Control The ability to put ISO on a dial. Switch to Nikon ISO adjustment style (press + hold ISO button and use wheel, let go of ISO button and it selects, instead of tap). I came from Canon many years ago, but Nikon's system is much faster! Disable expanded ISO (helps make ISO adjustment faster) This may not be something everyone agrees with, but I'd like them to remove auto-ISO from the ISO adjustment menu, and put it in its own menu. Why? Because I want 125 to be the hard stop at the bottom when I'm quickly trying to re-adjust ISO with the wheel. Alternatively, give me a way to assign switching to a specific ISO setting to a button with one press. Basically, ISO adjustment is too slow and fiddly! A menu option to toggle the camera between 1/3rd stop adjustments and 1/2 stop adjustments for shutter/aperture/ISO. 1/2 stop makes doing manual adjustments much faster. The ability to assign a button to turn on and off any interface element in the EVF. The one I want in particular is the grid-- I would love to be able to quickly turn this on and off as needed. Pixel-shift In-camera combination of pixel-shift, or at bare minimum some way for the camera to mark that the cameras are a pixel shift group so they don't get lost before I load them into the app on my computer. Autofocus A better system for switching between AF subject detection for face/various kinds of animals. Currently I need two buttons (face and subject) and I still need to go into the menus to switch between subject type! It does seem as though autofocus needs a little tuning. The box in continuous tracking mode tracks things well, but if you try and shoot at the same time it "misses" some of the shots. This feels like asking for the moon, given how much AF as improved, except that Canon/Nikon/Sony/OM does this pretty much bulletproof now. Fuji is close, maybe they can get to 100% in an update... Thats all! Honestly for me the "control" options are most important. I picked the X-H2 for the viewfinder, but If I'm going to give up manual shutter/ISO dials, the command dial system has to be perfect. Love it so far but there's a lot they could improve with little changes.

FHD240 is particularly bad on this X-H2S.  What is this elongated noise pattern in the highlights at ISOs greater than 1500--impossible to get rid of with temporal noise reduction in Davinci Resolve.  Probably not going to happen as it is most likely a function of the stacked sensor.
Improvements must be made ISO adjustments..  I don't really care what they are as long as changing ISO does not obscure the histogram.  Who at FujiFilm thought this was a good idea?  They need to be terminated!  How about when you press the ISO button (or any other assignable button), you can adjust the ISO with the front command wheel something like X-T3/T4 without obscuring the histogram?
Video autofocus does not require a Kaizen change--small incremental improvement.  We have been getting small--very small improvements for years while other companies have been making far greater advancements.  What we need is Kaikaku--radical change..
If there are multiple faces in and area, face detect jumps around from face-to-face like a whore conducting her love life.  Same thing with subject detect.  If there is mildly complicated background FujiFilm continues to finds birds in the bushes that do not exist spoiling the clip.  How about a firmware change that once you press record, the subject that was detected stays detected until the subject moves out of frame or you stop recording.
FujiFilm needs to get some engineers who see things differently and can design a world class autofocus system. They have the hardware to do it.  But does FujiFilm have the will?  No more of this insect and drone detect BS and calling it an improvement!  Who do they think they are fooling?  Just the FR crowd. LOL.
While I am on a roll.  How about a smoother IBIS.  The X-H2S does not represent much change from the X-T4.
Plus,  all the other things the previous posters suggested.
 

I like these.  Especially the Nikon style ISO hold and release switch.  Would be way faster and more intuitive.  I will add a few:
Improve the FHD240 on the X-H2S. It is incomprehensible that it is as bad as it is. Just why? Option to turn off NR entirely.  The -4 still has some NR. Option to output 4K signal through HDMI while recording 6.2K open gate internally. I have searched for this in the menu system and have not found it anywhere, so I am guessing it isn't currently an option. Also, I don't know if it's possible, processing-wise.  But if it is, I would like to see it. Turns out if you turn on HDMI Info in the output settings it will send out a 4K signal of your 6.2K open gate that any 4K monitor can read. Seems like adding a clean 4K output of it is not only possible then, but should be a no-brainer. Anamorphic desqueeze modes. More video monitoring options like vectorscope and waveform.  This is low priority for me though.  It's a small screen, and I can monitor this stuff externally (if I can monitor at all, which I can't currently in 6.2K!) ADDED: Locked 3-axis IBIS mode for wide angle lenses to get rid of the wobbling. ADDED: Object Tracking AF mode for video. For some reason just realized it's only a photo AF mode right now. But the fact that it exists makes me hopeful it could be added to video. Other than these things, I am pretty happy with my X-H2S.  I do not see what others are complaining about in the colors, etc., though maybe I will when I start editing more.  Who knows.  But the output I've seen from the camera looks superb.  If I find limitations, I'll work with it.
