hello,
Nothing complicated. You maybe miss the point.
Can you try this ? :
hold the FN button, and set DOF on this button.
then close lens at 8.
eye through EVF, you make focus on near thing, with an half press, and release the shoot button.
Then if you push the fn button you will see icon on EFV, and the real DOF of f/8. If you press another time the fn button, the back plan will be blur again.
That’s it.
I am so ashamed of my so bad english. Apologies for this, i just try to help
After that said, you should follow the official topic of xe3, and post your demands there instead of creating a new post. Or maybe not
