Canon 7D: C.Fn III -3 AI Servo AF Tracking Method
How to deal with intrusions when you are using the AI Servo for tracking? It is related to C.Fn III -1 AI Servo tracking sensitivity
- With 0, the default, the main focus point will switch and start to focus on the closer target. If I was photographing runners entering on the track at a stadium, this would be my choice. The AI Servo will switch to the main focus point and start tracking from the main focus point.
- With 1, the AI Servo will ignore the “intruding target”. The AI Servo will keep on tracking from the existing point in focus.
- My preference is 1, to ignore the “intruding target” and keep on tracking the “main target”.
- If I don't like it, I release my thumb from the AF-ON button and repress to re-acquire the target that I want.
