SAFETY PRECAUTIONS

• Do not look directly at the sun, through the lens. Doing so can cause damage to the eye or loss of eyesight.
• Do not leave the lens in direct sunlight without the lens cap attached, whether the lens is attached to the camera or not. This will prevent the lens from concentrating the sun's rays, which may cause a fire.
• The shape of the mount is very complex. Please be careful when handling it so as not to cause injury.

DC 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 sd Quattro / SD1 Merrill / SD1 digital camera, corresponding angle of view will be 45mm.
• If you use SD15 / SD14 / SD10 / SD9 digital camera, corresponding angle of view will be 51mm.

ATTACHING TO THE CAMERA BODY

Please refer to the camera's instruction manual for details on how to attach it to or detach it from the 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.

FOCUSING

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 "MF" 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 A 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.

LENS HOOD

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.3)

• 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.4)
  

FILTER

• 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.

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.

TECHNICAL SPECIFICATIONS

• Dimensions and weight include the SIGMA mount.
• The glass materials used in the lens do not contain environmentally hazardous lead and arsenic.
