Back Button Focus interrogation

[ElysiumFuji]

Hello everyone,

I recently bought my first Fuji camera.

Could you please enlighten me on a point I don't seem to have understood? Concerning the back button focus, i.e. the AF-ON button. I don't seem to be able to do what the videos explain: use the button for AF-C by holding it down, or for AF-S by pressing briefly and then releasing.

In my case, if I hold down the button, AF-C works fine. But if I press just once, nothing happens, apart from a short activation of AF-C as if I were going to keep pressing.

I've changed the option in my key settings, but both actions produce the same effect.

Have I misunderstood something, or do Fujifilm cameras simply not allow this?

Forgive me if this isn't very clear 😅

In order to use AF-ON/AF-C for back button focus you need to detach the focus action from the shutter button.

In the menu here:

Once the focus action is detached from the shutter button then AF-ON controls focus.
