How does manual focus of Canon 700d become automatic focus?

Hello; You are using a Canon 700D camera. Now focus manually. If you want to change to autofocus, that's easy. You can see that there is a button on the lens of the camera you are using, which is called the focus mode button. When you push it to autofocus, it means autofocus. When you push it to MF, it means manual focusing. All right.
