I just bought a Fuji x100f and right out of the box I notice something with the autofocus (maybe it's normal and I just need to understand the camera). When you push the shutter button half way and the camera focus automatically, the lens doesn't stop moving... like it's always trying to focus. I can see the green box in the viewfinder, meaning that the subject is in focus, but the lens continuous to move, like trying to focus, and you can hear and feel the motors working. It doesn't stop.
I'm not focusing on a moving subject, so I would think that the camera would focus my subject and stop working.
Is this a normal behaviour in this camera? It's some kind of mode that I could turn off?
Thanks for your time and help!
