Within the Z6-III Photo Shooting menu choices is “AF/MF subject detection options“. When you change from no subject detection and select a subject, the next menu item below it, “MF subject detection area” is no longer greyed out and you can make a few choices from three areas. What is am not understanding is what does MF subject detection area do. I understand full well "AF" subject detection, but I am not understanding the "MF" option and what it does and what functionality it provides.
