I found this forum in a link from another Fuji forum so I'm glad to be here.
Regarding Ken, he's a strong, unique personality and part of his identity is to rattle the pots and pans. He's a quirky, intelligent person who has opinions, like we all do. His presentation can be extremely off putting, but he's worth listening to when deciding on a new Fuji.
I agree with others here who say it's best to rent a new camera if possible, and compare to one's own knowledge base and shooting preferences.
I thought Ken raised a few valid points and others which were fit for the floor mounted circular filing cabinet. But they were his points as he saw them so good for him.
But irrespective of his views and his 4/10 rating, I bought an X-H2S and have to say that it is an exceptional camera. It is so fast, the subject detection system is phenominal and the EVF is in a different league to any of my FujiFilm cameras.
I have it side by side with my beloved X-H1, a camera that was hewn from rock, and whilst it doesn't quite have that same 'feel' of indestructability, it is superbly made and tactile wise, a level above the X-H1. What I mean by that is the controls are well damped and responsive, the shutter button is less touch sensitive (ie doesn't fire at the lightest touch), and the control wheels, whilst not clickeable, are precise. The joystick is not as well positioned as the X-H1 but as I have only had the camera for two days, it will improve as my muscle/brain memory kicks in. The extended grip is as good as, if not better than, the X-H1 and though still early days, I found the 100-400mm nicer to hold and use when on the X-H2S with or without either of the TC's.
As for the charger, never got one with my X-T4 and yes it is tight of FujiFilm but I am glad that they spent the money on the sensor and the overall package. It shouldn't and didn't put me off but I see where he is coming from.
PSAM is not a big deal for me, its on all my Sony's and on mylovely little X-S10 so it came natural to me. The C1-7 modes are just superb and if I had to trade the conventional dials just for this feature then I would...almost, as I still love the manual control nature of my other FujiFilm's. To be able to dial in my favourite settings and recall them at the click of a dial (and lock it should I wish) is fantastic and instant.
I have a Delkin Black 150 Gb CFExpress card as well as a SanDisk Extreme SD Card. Never had a CF before, it makes the SD card seem pedestrian and even when on high speed bursts it clears the buffer immediately.
I enjoyed Ken's review but I beg to differ with his conclusions and thoughts. As for muddy twixt the X-T4, I am not sure where he got that from but IQ is exactly the same as my X-T4 and X-S10 using all my FujiFilm lenses ......but many more images are 100% in focus and processed 4 x quicker than any other body.
It is a cracking camera.
The f-stop is not changing, which is the ratio stays the same. Constant aperture is really constant f-ratio., which means effective or virtual ratio. A truly manual constant aperture lens operates differently than by-the-wire lenses, which is why the older ones are so large, they have to maintain that ratio over their range. Newer lenses do it differently which is why they are referred to as having virtual constant ratios.
Btw, that Canon approach is pretty limited. Try that trick on a wterfall and you will see the waterfall change from falling water to shaving cream.
