    Limiting the Focus Distance Range
    This lens is equipped with a focus-limiting switch, which makes it ideal for use
    as a moderate telephoto or portrait lens. Lock the lens out of the macro range
    to shorten the focusing time by setting this switch to the LIMIT position instead
    of the FULL position.
    FULL: The lens will focus from 0.3m to infinity.
    LIMIT:
    The lens will focus from
    approximately 0.38m to
    infinity OR from approxi-
    mately 0.3m to 0.36m in
    the macro range.
    Attach/detach the lens to/from your camera according to the instructions in the
    manual provided with your camera.
    * When attaching/detaching the lens, be careful not to touch the electronic
    contacts on the lens mounting surface nor crush these contacts by strong
    impact.
    Use the appropriate sized threaded filters with these lenses. Be sure your filters
    are clean before taking a photo. Perfect photographs cannot be taken if the
    filter is dirty or when water droplets or other foreign particulates are on the filter.
    Clean the filter thoroughly before taking photographs.
    * Always use one filter at a time. If two or more filters are used together, or when
    a thick filter such as a polarized filter is used, vignetting (darkening at the
    corners of the exposed image) may occur.
    * Depending on the lens model, you may hear a sound from inside the lens
    when the lens is shaken lightly. This is the sound of the ball bearings that are
    designed to smooth the action of the focus ring. It does not indicate a prob-
    lem with the general functioning of the lens.
    Precautions for Use
    Attaching a lens hood
    Unlike a SLR camera using a silver halide film, a digital SLR camera
    produces a large measure of reflection due to its imaging sensor. It is
    therefore recommended that a lens hood be attached when you're
    taking photographs with a digital SLR camera. Especially when a
    wide-angle lens is used, a lens hood should be attached even indoors.
    The DX lens is designed exclusively for a digital SLR camera of
    APS-C size.
    Tokina’s DX lenses are deigned exclusively for use with digital SLR camer-
    as having an APS-C sized image sensor. Using the DX lenses with a digital
    SLR camera with an imaging sensor of a size larger than APS-C, or with a
    SLR camera designed for silver-halide film, will cause vignetting.
    Using Ultra-Wide Angle Lenses.
    If you are using a super/Ultra-wide angle lens in auto focus, it may not
    focus on the periphery (outer edges) of the frame in AF mode.
    Since the depth of field is an ultra-wide angle zoom lens is very deep,
    focus detection in the periphery of the frame becomes difficult for
    cameras set in multi-point auto focus.
    We recommend using a central focus detection setting on your camera
    when using auto focus with ultra-wide angle lenses.
    The Mark (certication mark for conformance with the European export inspection requirements) is shown on lenses containing electronic parts.
    The specication data is based on the use of the lens with a Nikon camera.
    Note on Macro Photography
    In macro photography, the subject and lens become very close and the magnifi-
    cation increases as a result. Therefore, even a slight vibration or movement of
    the camera can affect image quality. In macro photography, hold the camera
    securely to eliminate vibrations. For vibration-free photographs Tokina highly
    recommends the use of a tripod, cable release and/or a wireless remote control
    and an external flash.
    <Eective F-Value and Exposure Magnication>
    The F-value shown on the lens indicates the brightness of a subject located at
    infinity. The Maximum aperture of a lens is always measured with the focus at
    infinity. If the macro magnification is raised, the brightness of the subject will
    decrease. This reduced brightness is called the effective F-value, while the
    exposure correction corresponding to the decrease in subject brightness is
    called “exposure magnification.
    * If you are doing macro photography using a Nikon mount, the display on the
    camera body will indicate a change in aperture as the focus distance
    approaches the minimum value, even when the lenss F-value is set to F2.8
    (fully open), until the effective F-value finally reaches F5.6.
    Aperture Ring
    Lock the aperture at the minimum (Highest F number), otherwise, the shutter
    will not release.
    Exposure Correction
    When the macro magnification is increased, the brightness at the film plane will
    decrease. On a TTL auto-focus camera or when shooting with a TTL flash, the
    quantity of light passing through the lens is measured and the exposure is
    corrected automatically.
    If the exposure is measured using an external light meter or when a non-dedi-
    cated external flash is used, the exposure must be corrected by a corresponding
    increase (in exposure magnification) equal to the decrease in brightness from
    the change in macro magnification.
    The table shown at right lists the exposure magnifications for the different
    macro magnifications applicable to the 100mm F2.8 Macro D lens.
    <Macro Magnications in the Exposure Magnication Table>
    The table shown at right lists the
    exposure magnifications and aperture
    openings at different macro magnifica-
    tions of 1:10 and above. If you don’t
    want to change the aperture setting,
    correct the exposure by changing the
    shutter speed.

    Tokina's DX lenses are designed for use with digital
    single-lens reflex (SLR) cameras having APS-C sized
    sensors. Do not use DX lenses with digital SLR cameras
    having an imaging sensor of a size larger than APS-C,
    nor with a SLR camera designed for silver-halide film.
    The Tokina D lens can be used with both digital SLR
    cameras with APS-C size sensors, digital SLRs with full
    frame sensors and SLR film cameras.

    Descriptions of Parts How to Attach/Detach the Lens
    The lens normally focuses automatically when the focus mode switch on the
    lens is set to the Auto focus (AF) position. If the camera is in the manual-focus
    (MF) position, adjust the focus by looking into the finder and turning the manual
    focus ring. This lens also supports focusing through the use of a focusing aid.
    Focusing
    If the camera’s built-in flash is used, the light of the built-in flash will be partially
    obstructed by the lens, so the picture shows a large shaded area at the bottom
    of the image. Therefore, it is advisable to use an external flash when this lens is
    attached.
    Caution Regarding the Use of a Built-in Flash
    When photographing people with the aid of a flash, their eyes sometimes show
    as red in the image. This is called the “red-eye phenomenon. Follow your
    camera manual instructions on how to remove red eye.

    <How to switch from the Auto focus position to manual focus position>
    The lens focus mode can be switched between the
    auto focus (AF) mark on the lens barrel and manual
    focus (MF) positions at any time by moving the
    manual focus ring forward or backward. When the
    focus ring is moved back toward the mount the AF
    mark will be covered and the lens will only focus
    manually. Move the focus ring toward the front of the lens for auto-focus.
    * For lenses using either the Nikon or Canon mounting system, it is possible to
    use manual focus without switching the focus mode switch on either the
    camera body or the lens to the manual position.
    In the Auto focus position the manual focus ring turns freely.
    * For all Canon mounts and,

    F2.8 DX II / 12~28mm F4 DX
    Nikon mount, the built-in AF motor will be
    automatically turned off when the focus ring is switched to MF mode position.
    One-Touch Focus Clutch Mechanism
    A lens hood is designed to help reduce or prevent flare and ghost images that are
    caused by strong diagonal or side rays of light striking the front of the lens. We
    recommend that you use a lens hood at all times to ensure clear, problem-free
    photographs and to protect the lens.

    hood clockwise, as viewed from the front,
    until a click is heard. Then, confirm the
    position of the mark on the hood aligns
    with the position of the hood position
    Indicator on the lens.
    * When attaching the hood, turn it until you hear a click” to ensure a secure fit.
    If the hood is not attached properly, vignetting could occur.

    Macro Magnification
    “Macro magnification refers to the ratio of the
    image captured on film or the sensor to the actual
    subject size. For example, if a subject 3cm in size is
    captured as a 1cm image on film, the magnifica-
    tion is “1:3. The macro magnification is indicated
    above the focus distance. In the example shown
    at right, the focus distance is 0.32m, while the
    macro magnification is approximately 1:1.3.
    [11~16mm F2.8 DX]
    To securely install the hood, align the mark
    on the hood with the hood attachment
    indicator (
    ) on the lens, and then turn the
    hood clockwise, as viewed from the front,
    until a click is heard.
    Important-Confirm that the mark on the
    hood is aligned with the center index on
    the lens.
    <How to attach the lens hood>
    [100mm F2.8 Macro D]
    Place the lens hood on the lens by aligning
    the index ( ) on the hood with the hood
    attachment index dot (
    ) on the lens.
    Secure the hood by turning it clockwise
    (when viewed from the front) until it clicks
    into place. Grabbing the tip of the lens
    hood with a strong force will make it
    difficult to attach/detach the hood. When
    attaching/detaching the lens hood, do so
    by holding the base of the hood (the part
    attached to the lens).
