Greybeard - you're a legend. Thank you so much for taking the time. I've changed to Electronic Shutter and it solves the issue.  Didn't realise the mechanical was limited to 2000ss. And yes, you're correct about the ISO too. Thanks again!

Can the GFX100ii shoot video undercranked, for example 3 fps on a 24fps project frame rate? Step printing is something we use on many projects, so it'd be good to know before buying the camera. I can't see anything in the manual. Sounds like the XH2-S can do this, though again, I'm not sure. Thanks folks.

The max mechanical shutter speed for the X100VI at f2 is 1/2000. If you have the max sensitivity for Auto2 set to 3200 then the rear screen will show 3200 until you half press the shutter. 

Hi, did you find out the cost? I have the same issue

I have turned off the touch screen on both my Fuji cameras, it is a nuisance often.
