Olympus Infinity Super Zoom 330 - Manual (Page 21)

Shooting Range
The autofocus system is designed to handle
subjects that are among of below chart. If the
subjects are out of this shooting range, the "AF"
light in the viewfinder will blink, and the shutter
will not release.
However, the shutter may sometimes be released
erroneously when the subject is extremely close to
the camera.
When shooting in extremely dim light, the AF
illuminator on the front of the camera will emit a
beam of infrared light to measure the distance to
the subject. The AF illuminator has a range of
approximately 4 m (13.1 ft).
