CAUTION
• When using the Quick-Shift Focus System, keep pressing the shutter release button
after you achieve focus and before taking a picture. If you let go of the shutter release
button before taking a picture, autofocus will operate again when you press the
shutter release button again.
However, by configuring the camera's custom settings, you can take pictures without
autofocusing after letting go of the shutter release button. See the camera operating
manual for details about the setting procedure.
• When focusing with manual focus or the Quick-Shift Focus System, the mechanism
allows the focusing ring to rotate freely after it is set to the ∞ (infinity) or the minimum
focus distance ends. However do not attempt to rotate it any farther than these ends
as this will result in decreased performance.
