    							EF85mm f/1.2L II USM
    Thank you for purchasing a Canon product.
    The Canon EF85mm f/1.2L II USM lens is a
    high-performance medium telephoto lens
    developed for EOS cameras. It is equipped
    with a large-diameter, high-precision aspheric
    lens element to achieve a brightness of f/1.2.
    The lens is suitable for portraits and other
    types of photographs making full use of the
    large-diameter lens feature for nice
    background blur.
    ¡“USM” stands for Ultrasonic Motor.Features
    1. Large-diameter, high-precision aspheric lenselement for excellent imaging performance
    even at the maximum aperture.
    2. Ultrasonic motor (USM) for quick and quiet autofocusing.
    3. Electronic manual focusing detects electronically how much the focusing ring is
    being rotated for manual focusing.
    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.

    and taking pictures.
    aSafety Precautions
    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.
    • 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
    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.
    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

    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

    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:
    • Reorient or relocate the receiving antenna.
    • Increase the separation between the equipment and receiver.
    • Consult the dealer or an experienced radio/TV technician for

    2.Setting the Focus Mode
    ¡After autofocusing in ONE SHOT AF mode, focusmanually by pressing the shutter button halfway and
    turning the focusing ring. (Full-time manual focus)
    ¡However, full-time manual focus cannot be used under the following conditions.• When using the EOS 620, 650, 1000/1000F/REBEL/REBEL S, and
    1000N/1000FN/REBEL II/REBEL S II.
    • When taking photographs by setting the camera’s mode dial to Basic Zone modes.
    To   shoot in autofocus (AF) mode, set the focus mode
    swit ch to AF.
    To   use only manual focusing (MF), set the focus mode
    s witch to MF, and focus by turning the focusing ring.
    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 Lens
    Do not touch the front rotating parts of the lens
    while autofocus is active.
    3.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.
    F or accurate manual focusing on subjects at
    infinity distance, look through the viewfinder while
    rotating the focusing ring.
    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.
    4. Infrared Index
    Some EOS cameras cannot use infrared film. See
    the instructions for your EOS camera.
    ¡The infrared index position is based on a wav elength 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.

    5. 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. Numbers in the scale
    are in F values, and for example, if the shooting
    distance is 5m and the aperture is f/11, the
    sharp area will extend from about 4m to 7m.
    The depth-of-field scale is an approximate
    6. Hood
    The ES-79 II hood can keep unwanted light out
    of the lens, and also protects the lens from rain,
    snow, and dust.
    Attach the hood using the following procedure.
    ¡While pressing the button on the back of thehood, push it against the hood mount of the
    ¡Release the button and place the claws of the hood in the groove on the hood mount.
    The hood can be reverse-mounted on the lens
    f or storage.
    Pa rt of the picture may be blocked if the hood is
    not attached properly.
    7. Filters (Sold separately)
    You can attach filters to the filter mounting thread
    on the front of the lens.
    ¡Only one filter may be attached.
    ¡If you need a polarizing filter, use the Canon
    Circular Polarizing Filter (72mm).
    ¡To   adjust the polarizing filter, first remove the
    lens hood.
