Under certain unusual conditions, the camera’s autofocus system may not be able to function accurately. At these times, you
should use the “Autofocus Lock” setting (→p.25). Conditions which may require these settings include:
● A bright light source with the picture area such as the sun near your subject or a strong reflection from water or the windshield of a vehicle;
● A mirror or other strongly reflective surface near the center of your picture;
● Photographing black or very dark light absorbing subjects such as hair;
● Presence of flames, smoke or gaseous substances;
● Photographing through glass.
