    Thank you for purchasing a Canon product.
    Canon’s EF300mm f/2.8L IS USM, EF400mm f/2.8L
    IS USM, EF500mm f/4L IS USM and EF600mm
    f/4L IS USM are high-performance super-telephoto
    lenses, for use with EOS cameras. 
    ●“IS” stands for Image Stabilizer.
    ● “USM” stands for Ultrasonic Motor.
    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 stand on top of the lens case. You may fall and
    injure yourself. 
    Do not pile lens cases on top of one another as they
    may fall and cause injury.
    ● Do not leave the lens in excessive heat such as in a
    car in direct sunlight.  High temperatures can cause
    the lens to malfunction.
    Features1. The Image Stabilizer gives the equivalent effect
    of a shutter speed two stops* faster.
    2. Use of fluorite and UD lens elements giving superior definition.
    3. Ultrasonic motor (USM) for fast, quiet autofocus.
    4. Manual focusing is available after the subject comes into focus in autofocus mode (ONE SHOT
    AF).
    5. An AF stop button to pause autofocus whenever desired.
    6. Can be used with EF1.4 ×II/EF2 ×II extenders.
    7. A focus preset function for advance storage of focusing positions in memory to allow
    instantaneous focusing.
    8. Tight seal structure ensures excellent dustproof and drip-proof performance.
    9. Designed for lighter weight with parts made of magnesium alloy.
    *Based on [1/focal length] second. 
    Generally, it requires a shutter speed [1/focal length]
    second or faster to prevent camera shake.

    a Safety Precautions
    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 fire.
    This device complies with Part 15 of the FCC Rules. Operation is
    subject to the following two conditions: (1) This device may not
    cause harmful interference, and (2) this device must accept any
    interference received, including interference that may cause
    undesired operation.
    Do not make any changes or modifications to the equipment
    unless otherwise specified in the instructions. If such changes or
    modifications should be made, you could be required to stop
    operation of the equipment.
    This equipment has been tested and found to comply with the limits
    for a class B digital device, pursuant to part 15 of the FCC Rules.
    These limits are designed to provide reasonable protection against
    harmful interference in a residential installation. This equipment
    generates, uses and can radiate radio frequency energy and, if not
    installed and used in accordance with the instructions, may cause
    harmful interference to radio communications.
    However, there is no guarantee that interference will not occur in
    a particular installation. If this equipment does cause harmful
    interference to radio or television reception, which can be
    determined by turning the equipment off and on, the user is
    encouraged to try to correct the interference by one or more of
    the following measures:
    Attaching the strap
    Thread the end of the strap through the strap mount on
    the lens and then back through the clasp on the strap.
    Pull the strap tight and check that there is no slack in
    the clasp.

    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
    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.
    The lens mount has a rubber ring for enhanced
    dust- and water-resistance. The rubber ring may
    cause slight abrasions around the camera’s lens
    mount, but this will not cause any problems. If the
    rubber ring becomes worn, it is replaceable by a
    Canon Service Center at cost.

    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.
    2. Setting the Focus Mode3.Switching the Focusing
    Distance Range
    You can set the focusing distance range with a
    switch. By setting a suitable focusing distance
    range, the actual autofocusing time will be shorter.

    Switching the Focusing Distance RangeAF Stop Button
    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. AF Stop Button
    During autofocus operation, you can press the
    AF stop button to temporarily pause autofocus.
    If the shutter button is still pressed halfway
    when the AF stop button is released,
    autofocusing will continue as before.
    ●With the EOS 630/600, RT, A2/A2E/5, or 10S/10
    set to the AI Servo AF mode and continuous
    shooting, AF will not resume even after you let
    go of the AF stop button. Press the shutter
    release button halfway to resume AF.
    ● With the EOS A2/A2E/5 and 10S/10 set to the
    Sports mode, AF will not resume even after you
    let go of the AF stop button. Press the shutter
    release button halfway to resume AF.
    ● You can change the functions of the AF stop
    button using the camera’s Custom Function. For
    details, please refer to the camera’s instructions.
    The AF stop function also works in AI Servo AF
    mode.
