About Focusing
Hard-To-Focus Subjects
The camera automatically focuses your shots for you. In most cases you’ll get great
focus simply by centering the subject on the monitor and then half-pressing the shutter
release button.
In certain situations, however, autofocus may not produce optimal results. With subjects
such as shown in diagrams 1 to 3 below, the camera may not be able to focus at all:
the green lamp will blink and the camera will not shoot. In cases such as 4 and 5, it
may also happen that the camera will focus incorrectly: the green light may come on
solid (allowing you to shoot) even though the image is not properly focused. And if you
line up a shot as shown in case 6, the camera will focus on the background rather than
on the subjects.
