Canon EOS R Mirrorless and Canon DSLR Autofocus Systems Overview 
Canon autofocus systems are so easy to use and so effective that many photographers rarely switch to Manual Focus or MF (not to be confused with Manual exposure mode, denoted by M in the camera menu and on the mode dial, if your camera has one). But how do they work, and what do the different options mean?
