hi, I have some queries about the 7 AF points of my 350D. Hope anyone can explain.
Before i ask anything, all of us know that we can use either all 7 AF points on, or choose any AF point on.
1. When using all 7 AF points on and shoot, i realised only a few or one AF point will blink. How does the camera choose these points? and wat happened to those not blink? meaning those areas not focused?
2. When using only 1 AF point, does it mean that the remaining 6 AF points not focused and comes out blur?
3. When shooting a person, use which mode(7 or 1)?
4. Is it true that if I use 1 AF point to shoot a person and align that point at the person's face, only the face will be focused, the neck, shoulder will be out of focused?
I am confused. Please help.
