ENG-7
Focus mode switch
Focusing ring
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.
2. Setting the Focus Mode
zQuickly turning the focusing ring may result in
delayed focus.
zDue to the structural characteristics, the focus
lens driving speed may vary according to the
variation in the air temperature and posture.
zDo not touch the operating part in the front of
the lens while the focus lens is operating. If
external pressure is applied to the moving part,
the lens initialization may be performed to return
the focus lens to the correct position for control
purposes.
zThe lens’ focusing ring is electronic.
zWith a camera capable of electronic full-time
manual focus, manual focusing is possible
in both One-Shot AF and Servo AF modes.
However, this requires a change in camera
settings.
zWhen AF operation is set to One-Shot AF,
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.
Please refer to the camera’s instructions for details.

3. Control Ring
The control ring can be assigned the functions
that are commonly used with cameras, such as
shutter speed and aperture settings.
Control ring
The click action of the control ring allows you to
have a sense of how much it is being turned.
Please refer to the camera’s instructions for
details on how to use the control ring.
zThere are cases in which the sound of control
ring operations may be recorded when shooting
movies.
zThe clicking sensation of the control ring can
be removed by the Canon Service Center.

ENG-9
Set the image stabilizer switch to ON when you
want to use the Image Stabilizer.
zThis function provides image stabilization
appropriate for shooting conditions (such as
shooting still subjects, panning shots, and
closeup (macro) shooting).
zThe Image Stabilizer will work in combination
with cameras with in-body Image Stabilizer.
zSet the image stabilizer switch to OFF when
you are not going to use the Image Stabilizer.
4. Image Stabilizer
zThe shorter the focusing distance is, the less the
image stabilizer effect.
zThe Image Stabilizer cannot compensate for a
blurred shot caused by a subject that moved.
zThe Image Stabilizer may not be fully effective if
you shoot from a violently shaking vehicle or other
transportation.
zWhen using a tripod, it is recommended that you
set the image stabilizer switch to OFF.
zEven with a monopod, the Image Stabilizer will
be as effective as during hand-held shooting.
However, depending on the shooting conditions,
there are cases in which the Image Stabilizer
effect may be less effective.
