That's peculiar to fujis. I realized years ago that in AF they focus with the aperture closed (at fixed apertures depending on the light, if I remember well, not necessarily the chosen one; my old X-T10 with the 18-55 closed down till 7.1 and in medium light it focused at 5.6).

I have just verified with my X-T3, it's the same. But I didn't know that in MF with the AFL button it focuses fully open indeed. So thank you for letting me learn something useful.
