I am going through the 'AF Setting Guidebook of the 5D MKIII'. Great document.
Reading about all AF-related menu functions on page 5, I noticed in AF5 the menu option 'AF status in viewfinder'.
Now, maybe this question was raised before, just couldn't find it. So sorry if I raise it again:
I checked my 5D MKIII menu and this menuoption is not visible. I have the other 4 options that this Guidebook is showing.
My firmware is 1.1.3
What other menuoption must be enabled for 'AF status in viewfinder' showing up in the AF5 menu?
