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
) 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
) 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
).
●
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
).
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
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.
