Taking Pictures
The camera automatically focuses on your subject when you press the
shutter release button halfway. If, however, you want to quickly focus on
a specific point, you will need to select one of the camera’s focus modes.
This section explains the various focusing settings.
Choosing the Focusing Range
By default, the camera automatically focuses on subjects within a range
of approximately 40 cm to infinity. By setting the [Focus Limiter] (p.66) to
Off, you can focus on subjects within a range of approximately 15 cm to
infinity.
Set the focus mode when you want to quickly focus on close or distant
objects, when you want to keep everything on the screen in focus, or
when you want to focus manually (p.63).
Choosing the Focusing Area
By default, the camera focuses on the closest object in the middle of the
focus frame. Select another focusing option if you want the camera to
focus on a different point (p.65).
Subjects Difficult to Focus On
The camera may not be able to focus under the following conditions. In
this case, lock the focus on an object the same distance away as the
subject (by pressing the shutter release button halfway), then aim the
camera at your subject and press the shutter release button fully.
