Remedy
The camera may have difficulty in
focusing on such subjects as: low
contrast subjects (a white wall, a blue
sky, etc.), dark subjects, finely-patterned
objects, rapidly-moving objects. It is also
difficult to get proper focus when
shooting through a window or a net. Try
shooting using the focus lock (p.72), or
Manual Focus (p.108).
Locate the desired subject in the focus
frame (focusing area) in the center of the
display. If it is difficult to do so, first lock
the focus on the desired subject (focus
lock), and then move the camera to
recompose.
Set to , (Auto) or b (Flash On) (p.105).
The flash does not discharge in these
modes.
