So after spending about 3 weeks with X-H2s, I find myself liking more than I dislike, but some aspects aren't living up to my expectations.
CONTROLS
So, the controls are an issue for many people used to shooting with the X-T line of cameras... I personally love the X-Tx line of control and wish that were something they kept for the X-H2s, but they didn't. However, I do not consider this a deal breaker, as the 7 custom setups can more easily preset AF, shooting mode, EV Comp, AF Type, Burst Type, and IQ settings. This is all pretty intuitive and not a bad way to shoot over all.
AF PERFORMANCE
I find the AF top-notch and as good as I thought it was the day I received the camera. However, it has created a situation where I now find myself being in a whole new world of learning. Things like IS Stabilization cannot keep up with AF and Burst speed so I can see the limitations of this speed. This is honestly something I hadn't really even thought about.
Anyway, you can see it will lock on fast and you can snap the image really fast with good lighting.



HIGH ISO PERFORMANCE
In my opinion, the images are insanely good right up to ISO 6400 and that's pretty impressive. I never really went this high with my X-T4, because I found excessive noise at ISO 3200 with my X-T3 (maybe it was just the image processing chip or a poor sample on my part).
This image is taken at ISO 6400 using Auto-ISO with a peak ISO setting of 6400. The room had very low lighting and

IBIS AND OIS
So, this is the only area I find that camera struggling a little bit. When I first shot with the camera I was playing around with the 80 Macro OIS and I found the IBIS extremely good!
Since that time, I've tried it on the Fuji 35 F/1.4 and Sigma 56 F/1.4, but the performance was still only 3 to 3.5 stops and I could never get the 5 stops proclaimed without OIS being included in the equation. This is a bit of a disappointment to me as I was hoping for better and maybe the lenses will get some firmware to help this issue.
VIDEO
I really don't need to say much here, the camera does very well with video and it is really hard to beat the quality of this thing for video. If you're into video, you know what to expect here and my only note is that focus breathing was significantly less than with my X-T4.
IMAGE QUALITY
It's very good and I would say is pretty much what you would expect from Fuji.




OVERALL
I don't really have a lot of complaints about the camera, it has been excellent. I think my biggest issue has been the IBIS and the learning curve that comes along with a camera that can react as quickly as this can with top-notch accuracy. It's an excellent body and one I like a lot.
