    							EF-S18-55mm f/3.5-5.6 IS II
    Thank you for purchasing a Canon product.
    The Canon EF-S18-55mm f/3.5-5.6 IS II lens is
    a high-performance standard zoom lens
    developed for digital SLRs compatible with
    EF-S lenses*.
    It is equipped with an Image Stabilizer
    effective for hand-held shooting at slow
    shutter speeds.Features
    1. The Image Stabilizer gives the equivalenteffect of a shutter speed four stops faster*.
    This function provides optimal image
    stabilization depending on shooting conditions
    (such as shooting still subjects and following
    2. Aspheric lens element for excellent imaging performance.
    3. Great close-ups at 0.25 m/0.8 ft at all focal lengths.
    4. A truly round aperture hole results in a nicer background blur.
    *Based on [1/(focal length x 1.6)] second. Generally,
    it requires a shutter speed [1/focal length] second or
    faster to prevent camera shake (in 35mm format.
    With an EF-S lens, it would be [1/(focal length x
    1.6)] second).

    aSafety 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.
    • 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
    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.

    1Mounting and Detaching the Lens
    See your camera’s instructions for details on
    mounting and detaching the lens.
    ¡After detaching the lens, place the lens with the
    rear end up to prevent the lens surface and
    electrical 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.
    2Setting the Focus Mode
    If a hood (sold separately) is installed, you can
    turn the hood to adjust the focus.
    To shoot in autofocus mode, set the focus mode
    switch to AF.
    To use only manual focusing, set the focus mode
    switch to MF, and focus by turning the focusing
    ¡Do not touch the rotating parts of the lens while autofocus is active.
    ¡Do not adjust focus manually when the focus mode switch is set to AF.
    To zoom, turn the lens’ zoom ring.
    Be sure to finish zooming before focusing.
    Changing the zoom ring after focusing can affect
    the focus.
    4Hood (Sold Separately)
    The EW-60C hood can keep unwanted light out
    of the lens, and also protects the lens from rain,
    snow, and dust.
    Turn the hood in the direction of the arrow to
    attach it securely.
    The hood can be reverse-mounted on the lens
    for storage.
    ¡When attaching or detaching the hood, graspthe base of the hood to turn it. To prevent
    deformation, do not grasp the rim of the hood to
    turn it.
    ¡Part of the picture may be blocked if the hood is not attached properly.
    ¡Remove the hood when using the cameras built-in flash, otherwise it may obstruct the flash
    and result in a dark area at the circumference.
    5Image Stabilizer
    You can use the image stabilizer in AF or MF
    This function provides optimal image stabilization
    depending on shooting conditions (such as
    shooting still subjects and following shots).
    1Set the STABILIZER switch to  .¡If you are not going to use the imagestabilizer function, set the switch to  .
    2When you press the shutter button
    halfway, the Image Stabilizer will
    start operating.
    ¡Make sure the image in the viewfinder isstable, then press the shutter button the
    rest of the way down to take the picture.
    ¡The Image Stabilizer cannot compensate for a
    blurred shot caused by a subject that moved.
    The Image Stabilizer may not be fully effective if you shoot
    from a violently shaking vehicle or other transportation.
    ¡ The Image Stabilizer consumes more power
    than normal shooting, so fewer shots can be
    taken if you use the function.
    ¡When shooting a still subject, it compensates for
    camera shake in all directions.
    ¡ It compensates for vertical camera shake during
    following shots in a horizontal direction, and
    compensates for horizontal camera shake
    during following shots in a vertical direction.
    ¡ When you use a tripod, the Image Stabilizer
    should be turned off to save battery power.
    Even with a monopod, the Image Stabilizer will be
    as effective as during hand-held shooting.
    However, depending on the shooting environment,
    the Image Stabilizer effect may be less effective.
    ¡The image stabilizer function also operates when the
    lens is used with an Extension Tube EF12 ll or EF25 ll.
    ¡ 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.
    The image stabilizer in this lens is effective for hand-held shots under\
     the following
    ¡In semi-darkened areas such as indoors oroutdoors at night.
    ¡In locations where flash photography is prohibited, such as art museums and theater
    ¡In situations where your footing is uncertain.
    ¡In situations where fast shutter settings cannot be used. ¡When panning subjects in motion.
