Products Information
When the MFL switch is set to the LOCK position, the focus ring operation is disabled, but AF operation is possible. So please check if the setting is set to AF.
Also, even with the MF setting, there are some camera bodies that temporarily operate AF by operating the AF-ON button, so please check the camera body settings.
