Olympus 170 - Manual (Page 41)

The use of the Spot mode is
recommended in the following
cases:
• When there is an object in front
of the main subject.
• When the subject is on the edge
of the frame.
• When the background is
brighter than the subject (the
subject is backlit).
Difficult-to-Autofocus Subjects
Although this camera's autofocus
system can lock on virtually any
subject, under certain conditions,
such as ~ below, it may not
lock on the correct subject even if
the shutter releases. This can
happen either when the green
lamp lights or blinks rapidly.
