    Handling Cautions● If the lens is taken from a cold environment into a
    warm one, condensation may develop on the lens
    surface and internal parts. To  prevent condensation
    in this case, first put the lens into an airtight plastic bag
    before taking it from a cold to warm environment. Then
    take out the lens after it has warmed gradually. Do the
    same when taking the lens from a warm environment
    into a cold one.
    ● Do not leave the lens in excessive heat such as in a
    car in direct sunlight.  High temperatures can cause
    the lens to malfunction.

    a Safety Precautions
    ●Do not look at the sun or a bright light source
    through the lens or camera. Doing so could result in
    loss of vision. Looking at the sun directly through the
    lens is especially hazardous.
    ●Do not point the lens or camera at the sun or
    photograph it. This is because the lens concentrates
    the sun’s rays even when the sun is outside the image
    area or when shooting with backlight, which could cause
    malfunction or fire.
    ●Whether it is attached to the camera or not, do not
    leave the lens under the sun without the lens cap
    attached. This is to prevent the lens from concentrating
    the sun’s rays, which could cause a fire.

    See your camera’s instructions for details on
    mounting and detaching the lens.
    To  shoot in autofocus (AF) mode, set the focus
    mode switch to AF.
    To   shoot in manual focus (MF) mode, set the
    focus mode switch to MF, and focus by turning
    the focusing ring. The focusing ring always
    works, regardless of the focus mode.
    1. Mounting and Detaching the Lens2. Setting the FocusMode
    ● After detaching the lens, place the lens with the
    rear end up to prevent the lens surface and
    contacts from getting scratched.
    ● If the contacts get soiled, scratched, or have
    fingerprints on them, corrosion or faulty
    connections can result. The camera and lens
    may not operate properly. 
    ● If the contacts get soiled or have fingerprints on
    them, clean them with a soft cloth.
    ● If you remove the lens, cover it with the dust
    cap. To attach it properly, align the lens mount
    index and the 
    index of the dust cap as shown
    in the diagram, and turn clockwise. To remove it,
    reverse the order.
    After autofocusing in ONE SHOT AF mode, focus
    manually by pressing the shutter button halfway
    and turning the focusing ring. (Full-time manual

    3.Switching the Focusing
    Distance Range
    You can set the focusing distance range to 1.8
    m/5.9 ft. to infinity or 6.5 m/21.3 ft. to infinity. By
    setting the suitable focusing distance range, the
    actual autofocusing time will be shorter.
    If you use AF from outside the specified focusing
    distance range, the lens may stop focusing when it
    reaches the limit of the range. This is not a
    malfunction. If this occurs, press the shutter button
    halfway down again.

    4. Adjusting Zooming Resistance
    Move the zoom ring forward or backward to
    ou can adjust the zoom ring “touch”
    (resistance) as needed by holding the focusing
    ring in place and turning the zoom touch
    adjustment ring.
    ● Be sure to finish zooming before focusing.
    Changing the zoom ring after focusing can affect
    the focus.
    ● To   prevent unintended extension of the front of
    the lens, be careful not to set the zoom ring too
    T urn the zoom touch adjustment ring towards the
    word SMOOTH to reduce the zooming touch, or
    towards TIGHT to increase it. To lock the zoom
    ring in place, turn the zoom touch adjustment ring
    towards TIGHT until it stops.

    button halfway, the Image
    Stabilizer will start operating. 
    ●Make sure the image in the
    viewfinder is stable, then
    press the shutter button the
    rest of the way down to take
    the picture.
    5. Image Stabilizer
    You can use the image stabilizer in AF or MF mode.
    Set the STABILIZER switch
    to ON.
    ● If you are not going to use the
    image stabilizer function, set
    the switch to OFF.
    Select the stabilizer mode.
    ●MODE 1: Corrects vibrations
    in all directions. It is mainly
    effective for shooting still
    ● MODE 2: Corrects vertical
    camera shake during
    following shots in a horizontal
    direction, and corrects
    horizontal camera shake
    during following shots in a
    vertical direction.

    6. Tips on Using the Image Stabilizer
    ●In semi-darkened areas such as indoors or outdoors
    at night.
    ● In locations where flash photography is prohibited,
    such as art museums and theater stages.
    ● In situations where your footing is uncertain.
    ● In situations where fast shutter settings cannot be
    The image stabilizer in this lens is effective for hand-held shots under the following conditions.
    ●When panning subjects in motion.

    Tips on Using the Image Stabilizer
    ●The Image Stabilizer cannot compensate for a
    blurred shot caused by a subject that moved.
    ● Set the STABILIZER switch to OFF when using the
    camera on a tripod. If the switch is set to ON, the
    Image Stabilizer may introduce errors.
    ● Set the STABILIZER switch to OFF when you are
    taking pictures using the Bulb setting (long
    exposures). If the STABILIZER switch is set to ON,
    the image stabilizer function may introduce errors.
    ● The Image Stabilizer might not be fully effective in
    the following cases:
    •You shoot from a violently moving vehicle.
    •Y ou move the camera dramatically for a panning
    shot in Mode 1.
    •Y ou shoot using techniques other than following
    shots in Mode 2.
    ● The Image Stabilizer consumes more power than
    normal shooting, so fewer shots can be taken if you
    use the function.
    ● The image stabilizer operates for about two seconds
    even when your finger is off the shutter button. Do
    not remove the lens while the stabilizer is in
    operation. This will cause a malfunction.
    ● With the EOS-1V/HS, 3, ELAN 7E/ELAN 7/30/33,
    E/50/50E, REBEL 2000/300, IX, IX Lite/IX7, and
    D30, the Image Stabilizer will not work during self-
    timer operation.●The stabilizer is equally effective for hand-held
    photography and photography with a monopod.
    ● The image stabilizer function also operates when
    the lens is used with an extension tube EF12 II or
    EF25 II.
    ● When using extender EF1.4× II/EF2×II, you can
    use the Image Stabilizer with the following cameras:
    EOS-1Ds Mark III, EOS-1Ds Mark II, EOS-1Ds,
    EOS-1D Mark III, EOS-1D Mark II N, EOS-1D Mark
    II, EOS-1D, EOS 40D, 30D, 20D, 20Da, 10D, 5D,
    DCS3, D2000, D6000, EOS-1V/HS, EOS-
    1N/DP/HS/RS, 3, ELAN 7E/ELAN 7/30/33, ELAN
    7NE/ELAN 7N/30V/33V, ELAN II/ELAN II E/50/50E,
    3000/88, REBEL XS/500, REBEL 2000/300, REBEL
    T i/300V, REBEL T2/300X, REBEL K2/3000V, IX, IX
    ● Depending on the camera there may be image
    shake, such as after releasing the shutter. However,
    this does not affect shooting.
    ● If you set the camera’s Custom Function to change
    the assigned button to operate the AF, the Image
    Stabilizer will operate when you press the newly
    assigned AF  button.
