My X-T20 switches to EVF when there is an object within about 3 inches of the EVF. This often happens when I am using the LCD tilted up as a waist-level finder. I want it to only react to objects within less than an inch, since I never look through the EVF from 3-inches away. I have looked through the manual and settings and cannot find a way to do it.
How can I customize the distance at which the camera switches between LCD and EVF?
