Focusing
Focus Mode Switching
Switch between the autofocus mode and manual
focus mode on the camera. For details, refer to
your camera operating manual.
* The forms of focus mode switch vary with the camera.
Using Autofocus
Set the camera’s focus mode to AF, and press the shutter release button halfway
to autofocus.
• With the cameras having the AF button, you can also press the button
to autofocus.
Using Manual Focus
Set the camera’s focus mode to MF, and turn the focusing ring to focus manually.
Precautions When Using a Flash
• When the built-in flash is used with a 24 mm or shorter focal length at a 0.8 m or
shorter shooting distance, vignetting will occur. Use the built-in flash at a distance
of 0.7 m or more even if the focal length is longer than 24 mm. When the distance
is shorter, exposure control is incorrect and vignetting in the picture occurs.

Using the Quick-shift Focus System
When using the lens with PENTAX digital SLR cameras, you can focus manually
after autofocus is performed. Just turn the focusing ring to manually adjust the focus.
You can do this without switching the focus mode to MF.
<How to use the Quick-shift focus system>
1. Using the autofocus mode.
2. Hold down the shutter release button halfway (or hold down the AF button),
then turn the focusing ring to finely adjust the focus.
3. Finally, press the shutter release button fully to take a picture.
CAUTION
• Keep pressing the shutter release button (or AF button) after you achieve proper
focus and before taking a picture. If you let go of the shutter release button before
taking the picture, autofocus will operate again when you press the shutter release
button again.
• During autofocusing, the focusing ring will rotate.
Do not touch the focusing ring while autofocus is operating as it may cause
a malfunction.
