1. When the main subject in the focus
brackets is relatively small
When a person standing in front of a distant
background is positioned within the focus
brackets, as shown in Fig. E, the background
may be in focus, while the subject is out of
focus.
2. When the main subject is a finely
patterned subject or scene
When the subject is finely patterned or of low
contrast, such as a field filled with flowers, as
shown in Fig. F, focus may be difficult to
acquire using autofocus.
