Shooting Problem Subjects for the Autofocus
The autofocus may not work well on the following types of subjects.
•Subjects with extremely low contrast to the surroundings
•Subjects mixing close and far objects
•Subjects with extremely bright objects at the center of the composition
•Subjects that are moving quickly
To shoot these subjects, first aim the camera at an object at a similar distance, lock the focus and recompose the image with the desired subject, or use the manual focus.
