ABOUT FOCUSING
✍
MEMO
• While the focus indicator is lit, the focus will be locked (focus lock).
If you want to focus on another subject, take your finger off from the
shutter release button once to release the focus lock.
• If the focus indicator blinks, it indicates that focus has not been
achieved. In the AF Single mode (AF.S), you cannot take a picture
while the subject is out of focus. If the subject is too close to the
camera, move back and take the picture. If the camera still has difficulty
focusing (see page 101), the subject focus manually (see page 94).
