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 SD9, SD10, SD14 or SD15 digital cameras, corresponding angle of view will be 13.6-27.2mm.

ATTACHING TO CAMERA BODY

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 not just the lens cap, to avoid vignetting (fig.2).
  
• Filters cannot be mounted on the front of the lens.

SETTING THE EXPOSURE MODE

The sigma lens functions automatically after mounting to your camera. Please, refer to the camera instruction book.

FOCUSING AND ZOOMING

This lens features Sigma's built-in Hyper Sonic Motor (HSM). The HSM enables quick and quiet autofocusing.

SIGMA AF and CANON AF

For autofocus operation, set the focus mode switch on the lens to the "AF" position (fig.3). 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.

NIKON AF, PENTAX AF and SONY

For autofocus operation, set the camera to AF mode and set the focus mode switch on the lens to the "AF" position (fig.3). 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.

Zooming

Rotate the Rubber grip on the zoom ring to the desired position.

PREVENTION OF FLARE AND GHOST

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.

FLASH PHOTOGRAPHY

Built-in flash of your camera may not cover angle of view of this lens, and this may cause light fall-off at the corners. When external flash is used, flip wide panel of your flashgun down to cover flash's head, before taking picture. (This may not work with some flashguns, please test your equipment shootings beforehand)

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.
