FOR NIKON MOUNT

This lens includes an electromagnetic diaphragm mechanism, the same specifications as the E-type mechanism in Nikon AF lenses. The lens is compatible with the cameras listed in Table (A). (The models with the Ŭ mark require the latest version of the camera firmware to ensure compatibility.)

• It is not compatible with film single-lens reflex cameras.
• It is not possible to use the lens with the cameras in Table (B).
• For models not listed in Table (A) or Table (B), please refer to the camera's instruction manual to check for compatibility of E-type lenses.

FOR CANON MOUNT

It is not possible to register more than one lens of same description, although this lens is designed to accommodate the [AF Microadjustment] function built into digital SLRs.

ATTACHING TO THE 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.

SETTING THE EXPOSURE MODE

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

FOCUSING AND ZOOMING

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 ring.

• Please refer to camera's instruction manual for details on changing the camera's focusing mode.
• 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 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.

Also, this lens can offer [Full-time MF function] (Manual Override) by rotating the focus ring of the lens while auto focusing is in operation. For Full- time MF, set the focus mode switch on the lens to the "MO" position (fig.3).

• When using USB DOCK (sold separately) and its dedicated software, "SIGMA Optimization Pro", it is possible to select Full-time MF function ON / OFF, You can also adjust the amount of ring rotation to operate Full-time MF function. For further information, please refer to the SIGMA Optimization Pro "Help" menu.

<ZOOMING>

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

ABOUT OS (OPTICAL STABILIZER) FEATURES

This OS lens effectively compensates for image blurring caused by camera shake. 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 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 cameraÞs built-in flash, it will not cause any effect to the pictures.
• For Canon mount, the Optical Stabilizer (OS) function will not work with film SLR cameras except the Canon EOS-1V.

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.5)

• 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.

FILTER

• 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.
