    cameras* compatible with EF-S lenses.
    ¡“USM” stands for Ultrasonic Motor.Features
    1. An aspheric lens element and super UD lenselement afford excellent image delineation
    and ultra-wide zoom.
    2. Ultrasonic motor (USM) for quick and quiet autofocusing.
    3. Manual focusing is available after the subject comes into focus in autofocus mode (ONE
    SHOT AF).
    4. A truly round aperture hole results in a nicer background blur.

    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.

    1Mounting 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
    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  ¢index of the dust cap as shown
    in the diagram, and turn clockwise. To remove
    it, reverse the order.
    2Setting 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.
    4Infinity 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.
    To zoom, turn the lens’ zoom ring.
    Be sure to finish zooming before focusing.
    Changing the zoom ring after focusing can affect
    the focus.
