    							EF28-300mm f/3.5-5.6L IS USM
    The Canon EF28-300mm f/3.5-5.6L IS USM
    lens is a powerful high-performance zoom
    lens for EOS cameras equipped with an
    Image Stabilizer, and covering a wide range
    of focal lengths from wide angle to telephoto.
    •IS stands for Image Stabilizer.
    • USM stands for Ultrasonic Motor.
    1. The Image Stabilizer gives the equivalent
    effect of a shutter speed three stops faster*.
    The lens also has a second image stabilizer
    mode that is optimized for following shots of
    moving subjects.
    2. Aspheric and UD lens elements for truly exceptional imaging capability.
    3. Ultrasonic motor (USM) for quick and quiet autofocusing.
    4. Manual focusing is available after the subject comes into focus in autofocus mode (ONE
    SHOT AF).
    5. A truly round aperture hole results in a nicer background blur.
    6. Adjustable zoom ring touch lets you lock at any focal length.
    7. Tight seal structure ensures excellent dust- proof and drip-proof performance.
    *Based on [1/focal length] second. Generally, it requires
    a shutter speed [1/focal length] second or faster to
    prevent camera shake.
    Thank you for purchasing a Canon product.

    a Safety Precautions
    aPrecautions for using the lens with the
    EOS-1N RS
    When shooting with this lens attached to an EOS-1N
    RS, use -2/3 or -1/2 step exposure compensation.
    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.
    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
    wa rm  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.

    See your camera’s instructions for details on
    mounting and detaching the lens.
    1. 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  Kindex of the dust cap as shown in the
    diagram, and turn clockwise. To remove it, reverse
    the order.
    The lens mount has a rubber ring for enhanced
    w ater- and dust-resistance. The rubber ring may
    cause slight abrasions around the cameras lens
    mount, but this will not cause any problems. If the
    rub ber ring becomes worn, it is replaceable by a
    Canon Service Center at cost.
    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
    f ocusing ring. The focusing ring always works,
    regardless of the focus mode.
    2. Setting the Focus Mode
    After autofocusing in ONE SHOT AF mode, focus
    manually by pressing the shutter button halfway
    and turning the focusing ring. (Full-time manual
    f ocus)
    3. Switching the Focusing
    Distance Range
    You can set the focusing distance range to 
    0.7 m/2.3 ft. to infinity or 2.5 m/8.2 ft. to infinity.
    By setting the suitable focusing distance range,
    the actual autofocusing time can be shorter.
    If you autofocus outside the set focusing distance
    r ange, the lens may stop focusing at the start of
    the focusing range; however, this is not a
    malfunction. Press the shutter release button
    halfway again.
    5.Adjusting Zooming Resistance
    You can adjust the zooming “touch” (resistance)
    as needed by holding the focusing ring in place
    and turning the adjustment ring.
    Tu rn  the 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 adjustment ring towards TIGHT until
    it stops.
    4. Zooming
    Move the zoom ring forward or backward to
    z oom.
    • Be sure to finish zooming before focusing.
    Zooming after focusing can affect the focus.
    •T o prevent unintended zooming when not
    shooting, be careful not to set the zooming touch
    too loose.
    When you press the shutter
    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
    6. Image Stabilizer Settings
    You can use the image stabilizer in AF or MF mode.
    Set the STABILIZER switch
    to .
    • If you are not going to use the
    image stabilizer function, set
    the switch to  .
    Select the stabilizer mode.
    •MODE 1: Corrects vibrations in
    all directions. It is mainly
    effective for shooting still
    • MODE 2: It compensates for
    ver tical camera shake during
    f ollowing shots in a horizontal
    direction, and compensates for
    horizontal camera shake
    during following shots in a
    ver tical direction.
    7. 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
    • In situations where your footing is uncertain.
    •I n situations where fast shutter settings cannot
    be used.
    The image stabilizer in this lens is effective for hand-held shots under the following conditions.
    •When panning subjects in motion.
    ● MODE 1 ●MODE 2
    Tips on Using the Image Stabilizer
    •When you use a tripod, the Image Stabilizer
    should be turned off to save battery power.
    • 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 ll or
    EF25 ll.
    • Pictures may look distorted after being taken
    depending on the camera, but this doesnt affect
    • 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 cannot compensate for a
    blurred shot caused by a subject that moved.
    Set the STABILIZER switch to when you are
    taking pictures using the Bulb setting (long
    e xposures). If the STABILIZER switch is set to ,
    the image stabilizer function may introduce errors.
    • The Image Stabilizer might not be fully effective in
    the following cases:
    •Y ou shoot while riding on a bumpy road.
    •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.
    •W ith the EOS-1V/HS, 3, ELAN 7E/ELAN 7/30/33,
    IIE/50/50E, REBEL 2000/300, IX, and D30, the
    Image Stabilizer will not work during self-timer
