When I set my Fujifilm to AUTO mode, the focus points area seem to be only at the center of the screen.
Is there a way to make this to cover the whole area? So that if my subject is at the edges, it can also focus properly?
Many features are disabled or cannot be changed when Auto mode is enabled. In particular, the auto-focus mode and points cannot be changed in Auto mode. FujiFilm's Auto mode is fully automatic, which means the number of decisions the camera makes for the user is maximized. The more settings a user is allowed to customize, the less automatic it would be.
FujiFilm X-Series cameras are modeless by default. All settings can be changed or set to Auto, individually. This can be confusing for users who have come from other systems with separate Auto, Manual, Shutter Priority, and Aperture Priority modes.
To use "Shutter Priority", select a new shutter speed with the shutter speed dial. To use "Aperture Priority", turn on the aperture switch and rotate the ring (or thumb wheel). For full manual control, change both.
To make the camera automatically select all settings, similar to Auto mode, turn the all dials to "A" (aperture, shutter speed) or "AF" (focus). Also enable Zone focusing and face detection.
