Using the Quick-Shift Focus System (
-series cameras only)
If you use the lens with an
camera and the focus mode is set to autofocus, you can
focus manually after autofocus is achieved. Just turn the focusing ring to manually touch-
up the focus. You can do this without switching the focus mode to MF.
How to use the Quick-Shift Focus System
1. Using Autofocus
Set the camera’s focus mode switch to autofocus, then press the shutter button halfway
(or press the AF button) to autofocus.
2. Adjust the focus by turning the focusing ring.
3. Finally, press the shutter release button to take the picture.
CAUTION
• During the autofocus operation, the focusing ring does not rotate. Do not
turn the focusing ring during the autofocus operation. Doing so will cause a
malfunction.
• When using the Quick Shift Focus System, keep pressing the shutter button
(or AF button) after you achieve focus and before taking the picture. If you
let go of the shutter button before taking the picture, you will have to focus
all over again when you press the shutter button again.
