Can someone help me understand a bit more about the difference between dynamic area AF and 3D tracking? I shoot a fair amount of high school football and soccer games. Page 94 of the manual states that 21 point dynamic area is best for football games when "players are moving unpredictably." 3D tracking is recommended for subjects that are moving erratically." I don't really understand the difference between the two.
Also, does the focus point indicator move as the subject moves or do I simply keep the highlighted focus point on the subject? Typically I use a high burst rate when shooting soccer or football. Which of the two tracking methods works better when in Continuous High?
