    Thank you very much for purchasing a Sigma APO Tele Converter EX
    DG. The Sigma APO Tele Converter 1.4x EX DG provides a 1.4x
    increase in the master lens’ effective focal length, whereas the Sigma
    APO Tele Converter 2x EX DG doubles the master lens’ effective focal
    length. These tele converters have been designed to take full
    advantage of the optical performance of the master lenses for which
    they can be used. Please read these instructions before using the
    Sigma APO Tele Converter EX DG. Your camera’s instruction booklet
    also contains pertinent information about using lenses. Please refer to
    it along with these instructions.
    NOTICE: USABLE LENSES AND FUNCTIONS
    Sigma APO Tele Converter 1.4x EX DG and Sigma APO Tele
    Converter 2x EX DG are dedicated Tele Converter lenses,
    which should be used only with lenses listed in [Table 1]. If you
    mount a Sigma APO Tele Converter 1.4x EX or APO Tele
    Converter 2x EX to a lens that is not listed in [Table 1], it may
    damage the Tele Converter as well as the master lens.
    The dedicated lenses are listed in [Table 1] (as of February
    2009). Please also visit our web site for latest up-to-date
    information.

    Usable range of focal length or AF working distance varies
    depending on the camera in use. Please refer your lens’
    instruction manual for details.
    PENTAX AF mount Tele Converter does not support PENTAX SF
    series cameras.
    Do not use more than one teleconverter at a time.
    ATTACHING THE APO TELE CONVERTER TO THE LENS
    First, attach the APO Tele Converter EX DG to the master lens. Then,
    attach the lens and the tele converter to the camera body.
    When removing the APO Tele Converter EX DG or the master lens,
    please rotate the lens in the direction opposite to the direction used to
    attach the APO Tele Converter EX DG or lens.
    When the APO Tele Converter EX DG is attached to the camera
    body it will automatically function in the same way as the master
    lens. Please refer to the instruction booklet for your camera body for
    details.
    If using a lens with a SONY and attaching the APO Tele Converter
    EX DG to the camera body first, it may cause the AF mechanism to
    run idle.
    FOCUSING
    The lenses marked “AF” in [Table 1] will retain auto focus operation
    when used with a tele converter. Those lenses marked “MF” can only
    be used for manual focus. Please focus the lens automatically or
    manually according to the instructions provided for the camera or
    lens.
    If using lenses marked “MF” with a SONY, NIKON AF and PENTAX
    AF cameras, be aware that these lenses cannot focus precisely by
    auto focusing. Please be sure to use the manual focusing method
    when using these lenses with the APO Tele Converters.
    The speed of auto focusing, when using the tele converter, may be
    slightly slower than without the converter.
    EXPOSURE
    Using the APO Tele Converter EX DG decreases the effective
    aperture by one F-stop (with the APO Tele Converter 1.4x EX DG) or
    by two F-stops (with the APO Tele Converter 2x EX DG). However,
    exposure can be determined in the same manner as when using the
    master lens without a tele converter.
    If using a lens marked “ ” in [Table 1], the camera’s display will you
    the converted exposure information.
    When using a tele converter with a lens not marked “ ” in [Table 1]
    while using a hand-held exposure meter, you should increase the
    exposure reading by 1-stop for the APO Tele Converter 1.4x EX DG
    or by 2-stops for the APO Tele Converter 2x EX DG.
    If using lenses equipped aperture ring with NIKON AF mount of this
    Tele Converter, you need to set minimum aperture depending on the
    camera in use. Please refer your camera’s instruction booklet.
    If using lenses equipped aperture ring with PENTAX AF mount of
    this Tele Converter, you need to set A position depending on the
    camera in use. Please refer your camera’s instruction booklet.
    BASIC CARE AND STORAGE
    Avoid any shocks or exposure to extreme high or low temperatures
    or to humidity.
    For extended storage, choose a cool and dry place, preferably with
    good ventilation. To avoid damage to the lens coating, keep away
    from mothballs or naphthalene gas.
    Do not use thinner, benzine or other organic cleaning agents to
    remove dirt or finger prints from the lens elements. Clean by using a
    soft, moistened lens cloth or lens tissue.
    This lens is not waterproof. When you use the lens in the rain or
    near water, keep it from getting wet. It is often impractical to repair
    the internal mechanism, lens elements and electric components
    damaged by water.
    Sudden temperature changes may cause condensation or fog to
    appear on the surface of the lens. When entering a warm room from
    the cold outdoors, it is advisable to keep the lens in the case until
    the temperature of the lens approaches room temperature.
