Chings , how to use AF-ON ?? what's its difference from the AF-MF switch on the lens body ?

[checkylam]

AF-ON我得一個用途咋,開左liveview時,按實af-on個liveview就會自動對焦~~
唔知仲有無其他用途,請其他師兄補充~~

AF-ON always use for sport shooting with the AI servo mode. Keep pressing the AF-ON button so the IS and tracking always keep on no matter what action on the shutter button. It will decrease the chance loosing the tracking on AF by only pressing halfway of the shutter button

Chings, as I am still using camera without AF-ON, may I ask

can AF-ON set as FEL ?
