Shooting Problem Subjects For The Autofocus - Canon PC1057 User Manual

Shooting Problem Subjects for the
Autofocus
The autofocus may not work well on the following types of subjects.
• Subjects with extremely low contrast to the surroundings
• Subjects mixing close and far objects
• Subjects with extremely bright objects at the center of the
composition
• Subjects that are moving quickly
• Subjects with horizontal stripes
To shoot these subjects, first aim the camera at an object at a similar
distance, lock the focus (focus lock) or autofocus (AF lock) and
recompose the image with the desired subject. You can also use
manual focus.
Shooting with Focus Lock

1
Aim the AF frame at an object at a similar distance to
the subject you wish to shoot.
2
Press the shutter button halfway to lock the focus.
The AE setting will also lock when you do this. The exposure may
occasionally be incorrect if the difference between the two items is
too great. Use the AF lock function or the AE lock procedure
(p. 104) when this happens.
3
Keep it pressed while you recompose the image and
press the shutter button all the way to shoot the
image.
