- Suppose you have your subject at point A, and you and camera are at point B
- Lets invent 2 situations, each with an imaginary distance between points A & B:
- Situation 1: It has 10 meters between point A & B and NO camera zoom
- Situation 2: It has 20 meters between point A & B with the camera zoomed in to get a same composition as situation 1
- In both situations the photographer has pre manually focused on point A
- Now lets say in both situations a subject runs through point A and then a further 1 meter towards point B causing a loss of focusing accuracy.
- In theory: in situation 1 the focusing point is then 10% out, ie 1 meter error from a distance of 10 meters
- In situation 2 the focusing point is only 5% out, ie 1 meter error from a distance of 20 meters.
Therefore I'm imagining the focusing area would be less critical if you stood further back and zoomed in more.
Does that makes any sense? Would I be right in my assumption?
