SETTING THE FOCUS MODE SWITCH TO THE SERVO POSITION ziti
Predictive Autofocus Mode
When the camera senses subject movement during
the autofocus operation, the camera will automati-
cally switch the focus mode to the predictive autofo-
cus mode to measure the speed of a moving sub-
ject, and predict where it will be at the moment of
shutter release to maintain sharp focus on the sub-
ject. If the subject is moving too fast, the shutter
may not be released.
If the shutter release button is held at the halfway
position, the lens focuses continuously to follow the
subject. The shutter can be released even if the
subject is out of focus.
