Ok so while trying to understand the different AF modes, i have come to another learning stump, where i can't figure out when to use what..
One Shot AF: still subjects and snapshots..
AI Focus AF: used for unpredictable motion; Focsues as ONE shot, but swithces to AI Servo AF if the subject moves?? And focuses continously on the moving subject...Is this only if the Focus button is held down??
AI Servo AF: used for moving subjects and focuses continuously??
My questions are:
1) not clear when to use what??
2) Why not ALWAYS use AI FOCUS AF if it changes based on the subject, Automatically??
3) when is says, "focuses continously" is that only if i keep the button pressed, or does it lock the focus from when i first set up the shot??
