    This lens functions in the same way as a G Type auto-focus Nikon lens
    (without an aperture ring). Functions may be restricted depending on the
    lens/camera combination. For more details, please refer to the camera’s
    instruction manual.
    This Lens functions same as a FAJ Type (type without Aperture)
    auto-focus Pentax lens. Depending on the combination with camera some
    restrictions with its functions may result. For more details, please refer to
    instruction manual of the camera in use etc.
    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.
    Many accessories such as rear mounted teleconverters, extension
    tubes, etc., are specially made for designated lenses. Before you
    purchase such accessories, please check your Sigma lens to determine
    that it is compatible and that the accessories will function properly with
    The sigma lens functions automatically after mounting to your camera.
    Please, refer to the camera instruction book.
    This lens features Sigma’s built-in Hyper Sonic Motor (HSM). The HSM
    enables quick and quiet autofocusing.
    For autofocus operation, set the focus mode switch on the lens to the “AF
    position (fig.2). If you wish to focus manually, set the focus mode switch on
    the lens to the “M” position. You can adjust the focus by turning the focus
    For autofocus operation, set the camera to AF mode and set the focus
    mode switch on the lens to the “AF” position (fig.2). If you wish to focus
    manually, set the focus mode switch on the lens to the “M” position. You
    can adjust the focus by turning the focus ring. (In the case of Four-Thirds
    cameras it is necessary to switch the camera to MF mode as well)
    Please refer to camera’s instruction manual for details on changing the
    camera’s focusing mode.
    For Nikon, Pentax and Sony mounts, it is only possible to use AF with
    camera bodies which support motors driven by ultrasonic waves such
    as HSM. AF will not function if the camera body does not support this
    type of motor.
    This lens also permits manual focusing even in the autofocus mode.
    With the camera set to the One-Shot AF (AF-S) mode, it is possible to
    manually override the autofocus while the shutter release button is
    pressed halfway.
    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 contract. Special allowance is made for this at
    the infinity setting.
    The depth of field scale helps you to check the depth of field (the zone of
    sharpness) of your composition. For example in figure (3), the depth of
    field zone is shown when the aperture F16 is used.
    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.4)
    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.
    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
    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.
