camera, and turn the lens clockwise until you
hear a click.

rear end up and attach the dust cap to prevent
the lens surface and contacts from getting
scratched. Make sure the lens and dust cap
mount indexes are aligned when attaching the
dust cap.

ngerprints on them may result in faulty
connections or corrosion, which may lead to
malfunctions. If the contacts get soiled, clean
them with a soft cloth.
zThe lens mount has a rubber ring to improve
dust-resistance and water-resistance
performance. This rubber ring may cause
friction marks to appear around the camera’s
lens mount, although this will have no effect on
usage.
zRubber rings can be replaced at a Canon
Service Center. (chargeable)

2. Setting the Focus Mode
To shoot in autofocus (AF) mode, set the focus
mode switch to AF.
To use only manual focusing (MF), set the focus
mode switch to MF, and focus by turning the
focusing ring.
zQuickly turning the focusing ring may result in
delayed focus.
zThe lens’ focusing ring is electronic.
zWith a camera capable of electronic full-time
manual focus, manual focusing is always

manual focus is possible after autofocusing
has been completed by continuing to press the
shutter button halfway (electronic manual focus
function). However, this requires a change in
camera settings.
zWhen movie recording, the AF speed will be
slower than the still photo shooting mode. It is
possible to adjust the AF speed on the camera
by setting Movie Servo AF to [Enable].
Please refer to the camera’s instructions for details.
