Canon released this new AF guide for 1DX2 and it is of course applicable to most modern cameras with the 61 pt AF system although more so for 1DX2 and 5D4.

There have been similar previous guides and after reading this new one it does seem Canon has refined it and explanations are much better. I find it a good read for newcomers to the 61/65 pt system and even those of us who have had years learning the system can pick up a tip or two...
