Cause
Subjects difficult for Autofocus include

objects, fast-moving objects, and
landscapes seen through a window or
net.Focus on something at the same
distance as your subject, lock the focus
(by pressing shutter release button
halfway), aim at your subject, and press
shutter release button fully.
Position focusing target within the frame
(Focusing Area) at the center of the LCD
screen.If your subject is not within the
Focusing area, first focus on your subject
within the AF area, lock the focus (by
pressing shutter release button halfway),
then reframe your picture as desired, and
press shutter release button fully.
Set the Focus mode to q. (p.37)
When the Focus mode is set to q, normal
range pictures will be out of focus.
If the subject is too far away, the image will
be dark.Take the picture within the flash
range.
When taking a picture of a person against
a dark background, the person may
appear clearly while the background
appears dark because the flash does not
reach the background.If you select the /
or & mode on the virtual dial screen, both
the person and the night-scene will be
clear. (p.50)
Set to Auto or b(p.39)
The flash will not discharge in these
