  • Thank you very much for purchasing a Sigma Lens. In order to get the maximum
    performance and enjoyment out of your Sigma lens, please read this instruction
    booklet thoroughly before you start to use the lens.
    These are special lenses that are designated for digital cameras because the lens image
    circle is designated to correspond to the size of the image sensors of most digital SLR
    cameras. The specialized design gives these lenses the ideal properties for digital cameras.
    An image sensor element larger than those corresponding to APS-C cannot be used in
    digital cameras or 35mm SLR cameras. If such an element is used vignetting will occur
    on the picture surface.
    If you use SD14 or SD10 or SD9 digital camera, corresponding angle of view will be
    When this lens is attached to the camera body it will automatically function in the same way
    as your normal lens. Please refer to the instruction booklet for your camera body.
    On the lens mount surface, there are a number of couplers and electrical contacts.
    Please keep them clean to ensure proper connection. To avoid damaging the lens, be
    especially sure to place the lens with its front end down while changing the lens.
    The sigma lens functions automatically after mounting to your camera. Please, refer to the
    camera instruction book.
    For autofocus operation, set the focus mode switch on the lens to “AF” position.
    If you wish to focus manually, set the focus mode switch on the lens to the “MF” position.
    You can adjust the focus by turning the focus ring.
    To avoid damaging AF mechanism, please do not turn the focus ring manually while in
    the autofocus mode.
    The viewfinder of some Nikon AF cameras have indicators to display the focus status.
    The “ symbol indicates that correct focus has been set, “
    indicates that focus is
    set in front of the subject, and “
    indicates that focus is set behind the subject. When
    this AF lens is used with Nikon AF cameras in MF mode, please adjust the lens’ focus
    until the “ symbol is visible.
    When operating this lens in manual focus mode, it is recommended that correct focus be
    confirmed visually in the viewfinder rather than relying on the distance scale. This is
    due to possible focus shift resulting from extreme changes in temperature which cause
    various components in the lens to expand and contact. Special allowance is made for
    this at the infinity setting.
    Rotate the Rubber grip on the zoom ring to the desired position.
    Zoom Lock Switch
    This lens is also equipped with Zoom Lock Switch to eliminate the zoom creep when the
    lens is tilted down. Please set zooming ring to 18mm and set the zoom lock switch to the
    LOCK” position. (fig.2)
    The indication of the lens as “1:xx” on a focusing distance scale represent the magnification
    (commonly called the reproduction ratio). For example when you are in focus at the
    “1:3.9” position on the scale, a subject with an actual size of 3.9cm will have an image size
    of 1cm on the firm. (fig.3)
    This OS lens effectively compensates for image blurring caused by camera shake. Using
    the Optical Stabilizer function it is possible to get sharp results at shutter speeds
    approximately 3-4 stops slower than you could without using the OS function.
    Set the OS switch to ON (fig.4). Press the shutter button halfway down, confirm the image
    in the viewfinder is stable then take the picture. (It takes approximately 1 second to produce
    a stable image from the time of depressing the shutter button halfway).
    Do not use the Optical Stabilizer in the following situations:
    When the lens is mounted on a tripod. When using the camera in Bulb mode.
    The Optical Stabilizer function is powered from the camera. If the OS lens is attached to
    your camera and activated, shooting capacity of your camera will be lower than with
    conventional lenses used with the same camera. If you are not using OS, please turn
    OFF the OS switch, in order to prevent unnecessary battery consumption.
    Be sure to turn the OS switch to the OFF position before attaching or detaching the lens
    to the camera.
    The OS continues to operate after you release your finger from the shutter button, as long
    as the exposure meter displays the exposure value. Never remove the lens or remove the
    camera’s battery while the image stabilizer is operating as this could damage the lens.
    Although the viewfinder image may appear to shake immediately after shooting and/or at the start
    of the flash charge cycle of the camera’s built-in flash, it will not cause any effect to the pictures.
    If the lens is detached from camera or the camera power is turned off while the OS
    function is in operation, the lens may emit a chattering noise, but this is not a malfunction.
    A bayonet type detachable hood is provided with the lens. This lens hood helps to prevent
    flare and ghosted images caused by bright illumination from outside the picture area.
    Attach the hood and turn clockwise until it stops rotation. (fig.5)
    When taking photographs using the built-in flash, it is advisable to remove the lens hood so
    as to avoid cutting off any of the flash output, which could cause a shadow in the picture.
    In order to place the lens and hood into the storage case, you must first remove the
    hood, then replace it on the lens in the reverse position. (fig.6)
    Only one filter should be used at the time. Two or more filters and/or special thicker
    filters, like a polarizing filter, may cause vignetting.
    When using a polarizing filter with AF camera, use the “circular” type.
    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.
