Focus Tracking Mode
This mode allows you to define the
target and the camera will attempt
to
follow the movement of the subject
whilst you compose the picture and
take the image.
Focus tracking
Selecting target point
Target acquired icon shown
To set up the focus tracking mode
first align the target area onto
part of your subject which has
high contrast, good definition
edges and then press the AF/AE
Lock button. If the area has
sufficient contrast the camera will
be able to lock onto it. Ensure the
subject is within the camera focus
range by half
depressing the
shutter button to confirm focus
can be achieved.
The shape of the target
becomes
a square with a vertical cross
through it. Now acquired, if the
target moves you will see the
tracking icon follow the area you
defined in the set up procedure.
There are a number of
circumstances in which tracking
focus may not
follow the defined
subject. If the subject moves too
quickly (see the section under
continuous autofocus for an explanation
of this)
or the subject is too bright, or too dark, or if the background has similar
contrast to the subject then lock on may not be successful.
To cancel the autofocus tracking press the AF/AE lock button again. I
will
return to the face detection mode later in the guidebook when I
explain
the process of registering and deploying face detection.
