So I was one of the lucky ones to get the 5d3 on that blow out price from Adorama on Ebay last week.
Played with it all weekend and I understand all the components of the AF set up, i.e. setting the area, tweaking the responsiveness, etc.
What I don't understand is whether I'm doing it right when it actually comes to use.
I have it set up to back button focus with the *. Also have the DOF button switched to go into servo from one shot. I know I have to hit that grid key (farthest right) and then I have it set up to use the dial to choose between area options.
Ok, so now here's what I'm not sure. If I'm using the manual AF options (spot, cluster of 4, cluster of 8, etc.) I need to find my focus point and then manually move the camera around as the subject is moving holding the *, correct? Obviously, the bigger the AF area, the better I can track as I move around the camera. But I might not get the exact spot, i.e. getting nearest eye in focus on a tight shot. Might end up with the eye brow, nose, etc. if not use spot focus.
If I use the last 2 zone options, how does that work? Am I indentifying the focal point and it tracks it for me in frame, or does it automatically pick and I really have no ability to focus on the eye for instance?
The other thing I don't understand is the 6 cases. Is that only working during the automatic (zone) focus areas, or is it still in place on the manual options? How is it affecting the manual since I'm moving the camera around to keep track.
I guess maybe best to give you a real world example.
If I'm trying to shoot my 2 and 4 year old playing. How would you set up the AF? They're bouncing around, sometimes criss crossing in front of each other, sometimes still, sometimes moving forward, sometimes moving backwards, sometimes going slow, sometimes going fast.
I usually get in pretty tight, I would say torso shot, sometimes a real tight head shot. And using 2-8 f/stop range. Obviously I'm trying to nail, bright, crisp eyes.
