Although the autofocus system is very ac
curate, there are some subjects that present
some difficulty.
1) Subjects with low contrast (misty scenes,
light-colored or white objects).
2) Subjects with extremely low-light situa
tions (a dark room, night scenes).
3) Subjects having generally horizontal pat
terns (window blinds).
4) Subjects in extremely strong backlight
with strong reflections.
5) Subjects with an object in front of them
(caged animals).
6) Fast-moving subjects (difficult to keep
within the AF frame).
