Hey, ease up a bit, I'm just trying to learn here. And I'm not quite the idiot you think I am, I shoot sports and it's almost always center point only, I get good shots, as good as the pros at the tournaments I've gone to.
Perhaps you can explain how these defined set of parameters choose what they choose. Why does it sometimes choose what is the background, ignoring a decent foreground? Why does it sometimes choose stuff off to the side and other times not?
Did you look at those pictures and can you explain why it choose what it did?
Am I the only one scratching my head over that? For the record, the 5DIII does not do that, the 7DI did not do that, my 20D and 40D and T4i did not do that. But I'm sure the problem is me and the camera is perfect and all those other bodies just happened to do a better job.
Did you have iTR metering enabled for this? If you look at which AF points are selected in the shots you've provided you can see that the camera is always selecting the high contrast target closest to the camera which is exactly what the 5D3/7D1/70D will do as well as the 1DX if you turn iTR off. With iTR turned on, the camera should try to find faces in the frame to lock onto first and then go for the closest high contrast target. As others have said though, for this kind of scenario large area AF mode in AI Servo mode with iTR turned off is probably the worst mode you could have picked. In order of preference, I would have chosen Spot AF/Single Shot --> Single Point/Single Shot --> 65 point/Single Shot/iTR. Also, iTR only looks for faces in single shot mode; in Servo mode it samples the color underneath the "seed" AF point and then uses that information to help track the subject through the frame.
