How does Sony camera focus?

1, Sony MC2500 factory default autofocus. If in actual operation, the camera has been set to focus manually, then enter the menu to find the zoom ring setting, and then set it to not focus.

2. If you want the zoom ring to focus manually and sometimes switch to automatic, you can switch between automatic and manual by setting the "ASSIGN 1" key on the left side of the camera through the menu. When in use, the key switches between auto focus and manual focus.
