J IF CORRECT FOCUS CANNOT BE OBTAINED (FOCUS LOCK)
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.
1
Open the lens barrier.
The camera turns on in the shooting mode.
2
Look into the viewfinder and position
the AF target mark on the subject.
When shooting a hard-to-focus subject or a
fast-moving subject, point the camera at an
object about the same distance away as
the subject.
3
Half-press the shutter button until the
green lamp on the right of the viewfinder illuminates steady.
The focus and exposure are locked when the green lamp lights up.
4
Keeping the shutter button pressed
halfway, recompose your shot in the
viewfinder.
5
Press the shutter button fully.
