    The 10mm f/2.8 EX DC HSM Diagonal Fisheye lens is designed for use
    with digital SLRs with APS-C size image sensors and produces a
    rectilinear image which fills the frame. The Nikon, Sony and Pentax
    versions produce a diagonal angle of view of 180 degrees, the Canon
    version produces a diagonal angle of view of 167 degrees and the Sigma
    version produces a diagonal angle of view of 154 degrees.
    The specialized design gives these lenses the ideal properties for digital
    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.
    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.
    When you take a picture, please remove the lens cap and the adapter
    ring (fig.1-) not just the lens cap, to avoid vignetting.
    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.
    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.
    This lens has a short focal length and gives a wide depth of field and
    wide focusing area in front of and behind the subject. For this reason,
    the focusing position with AF may not match the position of the Distance
    Scale on the camera body.
    If the subject is too small, it may not be possible for the camera’s AF
    sensor to focus on it. Please ensure the subject is in the AF frame
    before shooting.
    Because of the extremely wide angle of view of this lens, flare and
    ghosting may occur much more easily than with other lenses. When you
    take a picture with this lens, please pay special attention to flare and
    ghosting which can occur when shooting near or directly into the sun or
    other very bright lights.
    Filters cannot be mounted on the front of the lens. If you wish to use
    filters, please use gelatin type. Please cut the gelatin filter, using the
    guide plate accessory as a pattern, and insert the filter into the filter holder
    at the rear of the lens. (fig.3)
    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.
