After I updated my X-T4 to the latest firmware (1.20). Exposure is locked in afc when focusing(half-press the shutter). Even though the shutter AE setting is off in menu. I found another X-T4 model with the same problem. But my friend's X-S10 with exactly the same settings don't have this situation. I heard that X-T3 with the latest firmware have the same problem. Don't know whether it's a bug or not?

Hmm, I can confirm the same issue with my X-T3 on Ver.4.10 firmware, indeed - no matter if "SET UP > BUTTON/DIAL SETTING > SHUTTER AE[1]" is set to ON or OFF for AF-C, once the shutter buttons is half-pressed the exposure is locked anyway.

The difference is "EL" (exposure lock) icon does appear when ON is selected, but not for OFF - yet exposure is locked still.

On the other hand AF-S works as expected - ON locks exposure on shutter button half-press (and "EL" icon is shown), and OFF does not lock exposure on shutter button half-press (neither is "EL" icon shown).
