Olympus stylus 800 ユーザーズマニュアル

When the subject you want to focus on is not in the center of the frame and 
you cannot position the AF target mark on it, you can focus the camera on 
another point at roughly the same distance (focus lock) and take the 
picture as explained below.

• When shooting a hard-to-focus or fast-

moving subject, focus the camera on an 
object about the same distance away as 
the subject.

• The green lamp lights when the focus 

and exposure are locked.

• When the green lamp blinks, the focus 

and exposure are not locked. Release your finger from the shutter button, 
re-position the AF target mark on the subject and press the shutter button 
halfway again.
