    							EF14mm f/2.8L II USM
    Thank you for purchasing a Canon product.
    The Canon EF14mm f/2.8L II USM is a high-
    performance super wide-angle lens designed
    for EOS cameras.
    ¡“USM” stands for Ultrasonic Motor.Features
    1.Aspherical and UD lens elements result in
    outstanding image delineation.
    2. Ultrasonic motor (USM) for fast, quiet focusing.
    3. Manual focusing is available after the subject comes into focus in autofocus mode (ONE
    SHOT AF).
    4. Close-up photography up to 0.2 m/0.7 ft.
    5. A truly round aperture hole results in a nicer background blur.
    6. Tight seal structure ensures excellent dust- proof and drip-proof performance.

    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
    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
    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
    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:
    • Reorient or relocate the receiving antenna.
    • Increase the separation between the equipment and receiver.
    • Consult the dealer or an experienced radio/TV technician for
    This Class B digital apparatus complies with Canadian ICES-003.

    See your camera’s instructions for details on
    mounting and detaching the lens.
    See the diagrams below for directions for
    removing and attaching the lens cap.
    ¡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
    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.
    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.
    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)
    To   shoot in autofocus mode, set the focus mode
    s witch to AF.
    To   use only manual focusing, set the focus mode
    s witch to MF, and focus by turning the focusing
    ri ng. The focusing ring always works, regardless
    of the focus mode.

    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. The numbers on the
    scale are F values, and for example, if the
    shooting distance is 0.5m and the aperture is
    f/16, the area in focus will extend from about
    0.3m to infinity.
    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.
    4. Infrared Index
    Some EOS cameras cannot use infrared film. See
    the instructions for your EOS camera.
    ¡The infrared index position is based on awav 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.
    6. Filter Holder
    There is a gelatin filter holder at the rear of the
    lens. Cut the gelatin filter to fit within the white
    frames. Then insert the gelatin filter into the filter
    ¡Only one filter can be used.
    ¡When you use a gelatin filter, ghosting mayappear in the image.
