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.
