Optimizing focus
When the camera cannot auto focus, the focus brackets turn red. This indicates the
picture may be out of focus because the subject is out of the focus range or the scene
has low contrast.
If you are recording a video or taking a picture with a shooting mode (see Using the
shooting modes on page 16) other than
Close-up and cannot focus, it will still take
the picture. Try releasing the Shutter button, reframing, and then pressing the Shutter
button halfway down again. If the focus brackets are still red:
For pictures and video clips: If the scene has low contrast, use Focus Lock (see Using
Focus Lock on page 13) and aim at a point on the subject that has more colors or
crisp edges.
For pictures only:
● Select a shooting mode more appropriate for the scene you are capturing (see Using
the shooting modes on page 16).
● If the subject is too close (less than 100 mm or 4.7 in), move farther away from the
subject or use
Close-up (see Close-up under Using the shooting modes
on page 16).
If the camera is set to
Close-up and cannot focus, the camera will not take the picture.
Try one of the following:
● Move within the
Close-up range (100 mm to 1 m or 4.7 to 39.4 in) or set the
camera to
Auto (see Auto under Using the shooting modes on page 16).
● In low contrast scenes, use Focus Lock (see Using Focus Lock on page 13).
Using Focus Lock
Use Focus Lock to focus on a subject that is not in the center of the picture, to capture
action shots more quickly by pre-focusing in the area where the action will occur, or to
focus in low light or low contrast situations.
1. Frame the subject for your picture within the focus
brackets. In low light or low contrast situations,
frame a brighter or higher contrast object.
2. Press the Shutter button halfway down.
3. Hold the Shutter button halfway down and re-
frame.
4. Press the Shutter button all the way down to take
the picture.
Optimizing exposure
When you are taking a picture and press the Shutter button halfway down, the camera
also measures the light level to set the proper exposure.
