HOW TO USE AUTOFOCUS
I
n such cases, please use one of the following focusing methods.
1. Use the Focus Lock function to focus on another subject, which has a similar
focusing distance as your subject.
2. Set the lens to MF mode and focus manually.
SELECTING THE AUTOFOCUS MODE
Press the AF mode button and turn the “C”-dial to select either
(Single AF
Mode) or
(Continuous Mode) icon on the LCD panel.
SINGLE AF MODE
Depress and hold the shutter button “Half-way”
to activate the autofocus function. In order to
avoid out of focus exposures, the shutter cannot
be released until the subject is in focus. This is
called “focus priority”. Focus indicator appears
in the viewfinder, when the camera focuses on
the subject and the focus is locked. Press the
shutter button the rest of the way to take the
picture. If the camera cannot focus on the
subject properly, remove your finger from the
shutter button and press again.
Focus indicator will blink, if the subject is out of focus.
Use your camera in this mode for regular photography.
CONTINUOUS AF MODE
Press the shutter button “Half-way” to activate the autofocus function. If the subject is
in motion, the camera will focus continuously with motion prediction function. You can
release the shutter any time, even if the subject is not precisely in focus. However,
depending on the subject situation, (i.e. speed and direction of moving subject, the
lens and shutter speed etc.) there is a possibility that the picture may be out of focus.
Focus indicator will not appear.
Autofocus lock does not work.
Depending on some unusual conditions of the subject, sometimes autofocusing is
not possible.
