Continuous
At Continuous setting (
AF C
), the shutter can be released rapidly
before the lens is focused in order to capture a split-second shot (in
Single Shot
, an exposure cannot be made until the camera has
had time to focus). However, the camera will continue to focus if
a moving subject is within the focusing zone or if you recompose,
even though the shutter release button is half pressed.
One method to exploit this feature when photographing in a rap-
idly changing situation such as photojournalism, for example, is
to keep the shutter release button pressed down. In this way the
lens focuses constantly (according to the focusing zone) and by
momentarily releasing the pressure on the shutter release and then
immediately pressing again, you minimize the amount of time
needed for the lens to check focus, thus ensuring a split-second
shot at optimum focus.
Autofocus mode
Autofocus is set via the control wheels in the following manner:
In camera active mode:
1) Press the
AF
button on the grip.
2) Turn the front control wheel to:
Single Shot
or
Continuous
as required.
3) Press
Save
(
DRIVE
button) to store the setting.
Manual override in autofocus mode
Manual override is always possible in automatic focus mode with-
out any need to make a new setting; just rotate the focusing ring
in the conventional manner. As the lens barrel does not rotate in
autofocus mode, you can hold the focusing ring for instant manual
adjustments as you would with a conventional lens. However, to
retain the new manual focus adjustments, you must maintain the
pressure on the shutter release button. You can instantly return
to the automatic focusing mode by releasing the pressure on the
shutter release button first and then pressing the release button
halfway again.
The instant manual override facility produces a convenient way of
working. You can take advantage of autofocus while retaining an
instantly adjustable manual focus check if preferred for pin-point
accuracy without making any changes in the settings.
Another method for users who prefer more manual focus control
while maintaining the benefits of the accuracy of autofocus is to
set the camera to Manual focus and the User button to AF (Single)
drive (see ‘User button function list’).
Focus is then adjusted manually with the focusing ring as normal
but when the User button is pressed, the autofocus facility temporar-
ily operates in AF S mode. After the new focus adjustment has been
made automatically, the camera reverts immediately to manual
focus control when the User button is released. Therefore, you can
recompose the picture without having to maintain pressure on the
release button in order to retain the newly automatically made
focus setting
.
