    Thank you for purchasing a Canon product.
    The Canon EF135mm f/2L USM, the EF200mm
    f/2.8L II USM, the EF300mm f/4L USM, and the
    EF400mm f/5.6L USM are high-performance
    telephoto lenses designed for EOS cameras.
    ¡“USM” stands for Ultrasonic Motor.Features
    1. UD lens elements (in the EF135mm f/2L
    USM, the EF200mm f/2.8L II USM, the
    EF300mm f/4L USM, and the EF400mm
    f/5.6L USM) and super UD lens elements (in
    the EF400mm f/5.6L USM) for excellent
    imaging performance.
    2. Ultrasonic motor (USM) for quick and quiet
    3. Manual focusing is available after the subject
    comes into focus in autofocus mode (ONE
    SHOT AF).
    4. The lens is compatible with Extender EF1.4X

    aSafety 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
    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.

    							ENG-4 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 
    Kindex of the dust cap as shown
    in the diagram, and turn clockwise. To remove it,
    reverse the order.
    1.Mounting and Detaching the Lens2.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
    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. The focusing ring always works,
    regardless of the focus mode. 
    4.Infinity Compensation Mark
    To compensate for shifting of the infinity focus
    point that results from changes in temperature.
    The infinity position at normal temperature is the
    point at which the vertical line of the L mark is
    aligned with the distance indicator on the
    distance scale.
    For accurate manual focusing on subjects at
    infinity distance, look through the viewfinder while
    rotating the focusing ring.

    3.Switching the Focusing Distance Range
    You can choose the focusing distance range with
    a switch. By setting a suitable focusing distance
    range, actual autofocusing time can be shorter.
    ¡EF135mm f/2L USM :
    q0.9 m / 3.0 ft. – ∞w1.6 m / 5.2 ft. – ∞
    ¡EF200mm f/2.8L II USM :
    q1.5 m / 4.9 ft. – ∞w3.5 m / 11.5 ft. – ∞
    ¡EF300mm f/4L USM :
    q2.5 m / 8.2 ft. – ∞w6 m / 19.7 ft. – ∞
    ¡EF400mm f/5.6L USM :
    q3.5 m / 11.5 ft. – ∞w8.5 m / 27.9 ft. – ∞
    If you autofocus outside the set focusing distance
    range, 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. 
    6. Depth-of-Field Scale
    The depth of field is the distance in front of and
    behind the plane of focus on the subject that
    appears sharp. The depth of field is indicated by
    the area between the depth-of-field scale lines
    below the distance scale.
    The number on the scale is the F value.
    The depth-of-field scale is an approximate
    The infrared index corrects the focus setting
    when using monochrome infrared film. Focus on
    the subject manually, then adjust the distance
    setting by moving the focusing ring to the
    corresponding infrared index mark.
    5. Infrared Index(EF200mm f/2.8L II USM • EF300mm f/4L
    USM • EF400mm f/5.6L USM)
    Some EOS cameras cannot use infrared film. See
    the instructions for your EOS camera.
    ¡The infrared index position is based on a
    wavelength of 800 nm.
    ¡Be sure to observe the manufacturer’s
    instructions when using infrared film.
    ¡Use a red filter also when you take the picture. 
    Adjusting the Revolving MountYou can loosen the orientation lock-knob on the tripod mount to allow it to rotate as needed to fit a
    particular camera model for switching between vertical and horizontal positions.
    The EF200mm f/2.8L II USM lens can be used with the A II (B) tripod mount ring, sold separately.
    DetachingUse the following procedures to remove and attach the tripod mount.
    Turn the locking knob
    counterclockwise until it
    becomes loose (about 3 turns),
    and pull the knob in the direction
    of the arrow to release the collar.With the collar open,
    remove the tripod mount.To install, while pulling the
    locking knob, bring the collar
    to the original position, and
    tighten the locking knob
    If the foot of the tripod mount overlaps the switch, loosen the orientation locking knob on the tripod mount to
    move the foot.
    7.Using the Tripod Mount (EF200mm f/2.8L II USM • EF300mm f/4L USM • EF400mm f/5.6L USM)
    The tripod mount can be attached to or detached from the lens while the lens is attached to the camera. 
    8. Hood
    EF135mm f/2L USM • EF200mm f/2.8L II USM
    Attach and align the hood to the hood mount on
    the front of the lens, and turn the hood as shown
    by the arrow to secure it.
    The hood can be reverse-mounted on the lens
    for storage.EF300mm f/4L USM
    Bring the hood out from the end of the lens until
    it stops. For storage, reverse the procedure.
    EF400mm f/5.6L USM
    Bring the hood out from the end of the lens until
    it stops and turn in the direction of the arrow. For
    storage, reverse the procedure.
    EF135mm f/2L USM • EF200mm f/2.8L II USM
    ¡Part of the picture may be blocked if the hood is not attached properly.
    ¡When attaching or detaching the hood, grasp the base of the hood to turn it. To prevent deformation, do not
    grasp the rim of the hood to turn it.
    The lens hood can reduce unwanted reflections and also protects the front of the lens from rain,
    snow, dust, and other substances. 
    9. Filters (Sold separately)
    You can attach filters to the filter mounting thread
    on the front of the lens.
    ¡If you need a polarizing filter, use the Canon
    Circular Polarizing Filter.
    ¡To adjust the polarizing filter, first remove or
    store the lens hood.
    10. Close-up Lenses 
    (Sold separately)
    Attaching a 500D Close-up Lens enables close-
    up photography.
    The magnification will be as follows:
    ¡EF135mm f/2L USM (72mm)
    0.48× – 0.27×
    ¡EF200mm f/2.8L II USM (72mm)
    0.57× – 0.39×
    ¡EF300mm f/4L USM (77mm)
    0.82× – 0.59×
    ¡EF400mm f/5.6L USM (77mm)
    0.91× – 0.78×
    ¡Close-up Lens 250D cannot be attached
    because there is no size that fits the lens.
    ¡Manual focusing is recommended for accurate
