Hi Doug,
Thanks for your comments.
That said, it seems that the OP missed something, which may be diagnosed as bad focus. Looking at the real image coming of the sensor at actual pixels, I don't think it can be bad advice.
I don't know how exactly the XF can focus, and I have not seen any test of focus accuracy on the XF.
With say the Fuji GFX we are in better shape, as Jim Kasson has made a lot of excellent testing on that camera.
Just as an example:

From the same test. Sony A7rII has less issues:
I have never seen such tests with Phase One.
In the figures above, you wouldn't like to have the CoC exceed say 1.5 times the pixel pitch.
As I said, I have not seen any tests like that on Phase One. Jim only tests things he plans to buy.
Best regards
Erik
Thanks, I know the definition of proxy.
I was disagreeing with your use of the word “only” in “live view is the only way to achieve correct focus”
It’s just flat out wrong to say that. Live view is very often a great way to focus. But there are many ways to achieve correct focus. In many cases live view isn’t even the fastest, easiest or most consistent.
