FIND THE SWITCH
Y ou won’t find a manual focus option on the majority of EOS cameras. To use manual, you’ll generally need to set the AF/MF switch on the lens to MF – look for ‘MF’ or ‘M Focus’ on the camera’s display(s) and in the viewfinder to confirm the change. If you’re using a lens that isn’t equipped with a focus mode switch, then you’ll need to set ‘MF’ in the menu or via the dedicated button (or customizable button) on the camera, if present.
Many lenses offer full-time manual focusing (FTM), which means that you can turn the focus ring to touch up the focus even when the focus switch on the lens is set to AF.
