My X-T20 switches to EVF when the LCD it tilted out. I know some cameras automatically disable the EVF when the LCD is pulled out, since the only reason to pull the LCD out is to use it. How can I set my camera to automatically disable EVF when the LCD is pulled out?
The Fujifilm X-T20 does not have that feature. There is no way to add because the camera has no idea that the LCD is pulled out. On those with that feature, there is usually a sensor or mechanical switch that gets pushed in when the LCD is flush against the body which enables the camera to behave differently.
