    Safety Precautions
    1.
    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.
    2.
    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
    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.
    1. Mounting and Detaching the Lens
    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 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, and turn clockwise. To remove it, reverse the order.
    2. Setting the Focus Mode
    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.
    After autofocusing in ONE SHOT AF mode, focus manually by
    pressing the shutter button halfway and turning the focusing
    ring (Full-time manual focus)
    .
    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
    .
    For accurate focusing in MF on subjects at infinity distance, look
    through the viewfinder while rotating the focusing ring.
    4. Infrared Index
    The infrared index corrects the focus setting when using
    monochrome infrared film. Focus on the subject in MF, then
    adjust the distance setting by moving the focusing ring to the
    corresponding infrared index mark
    .
    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.
