lease button fully.

your finger off the shutter release button.
• When the drive mode switch is set to the
Consecutive-Frame Mode [ Oil ], the lens focuses
each time you release the shutter.
• When using the SMC Pentax-F Soft 85mm f/2.8
lens, set the aperture between f/2.8 and f/4.5. See
page 52 for details.
Predictive Autofocus Mode
When the camera senses subject movement during the
autofocus operation, the camera will automatically
switch the focus mode to the predictive autofocus
mode to measure the speed of a moving subject, and
predict where it will be at the moment of shutter release
to maintain sharp focus on the subject.
• If the subject is moving too fast, the shutter may not
be released.
