On the lens mount surface, there are electrical contacts. Please be careful with their handling as scratches or dirt on them could cause malfunctions or damage.

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 (fig.3). You can adjust the focus by turning the focus ring.

• Please refer to the 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 the correct focus be confirmed visually in the viewfinder rather than relying on the distance scale.
• For the Sony E-mount lens, only MF is available during video shooting, depending on the camera.

This lens also permits manual focusing even in the autofocus mode. While half-pressing the shutter button, rotate the focus ring to adjust the point of focus. (For the Sony E-mount lens, please set the focus mode of the camera to [DMF.)

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 (except for the Sony E-mount lens).

The default setting of the Full-time MF function varies for each mount.

• When using USB DOCK (sold separately) and its dedicated software, “SIGMA Optimization Pro”, it is possible to select the Full-time MF function ON/OFF, You can also adjust the amount of ring rotation to operate the Full-time MF function. For further information, please refer to the SIGMA Optimization Pro “Help” menu.
• SIGMA Optimization Pro can be downloaded free of charge from the following website: http://www.sigma-global.com/download/

DEPTH OF FIELD SCALE

The depth of field scale helps you to check the depth of field (the zone of sharpness) of your composition. For example in Figure (4), the depth of the field zone is shown when the aperture F16 is used.

TRIPOD SOCKET AND COLLAR

This lens is equipped with a tripod socket. When you loosen the locking knob on the collar, the lens and camera can rotate freely to easily position the camera horizontally or vertically (fig.5).

It is possible to remove the lens’ tripod socket, for more convenient hand-held photography, if desired.

1. To do so, first, loosen the tripod collar locking knob, and, align the index mark of the collar, with the REMOVE position (fig.6).
2. Then, pull the tripod collar straight back, as shown in Fig. 7, removing the collar.

• When you wish to re-attach the tripod collar to the lens, please reverse the procedure above.
• Please, do not set the tripod collar to the REMOVE position, except when you are removing, or attaching, the tripod collar, as the lens may inadvertently detach from the collar and fall. Also, please remember to tighten the locking knob to prevent the lens from rotating unintentionally.
• When the lens is mounted on the camera, the tripod collar cannot be removed from the lens.
• This product is compatible with the Arca Swiss screw knob clamp. Please ensure that it is screwed and fixed tightly. This product is not designed for lever-type clamps. There are some lever clamps available that do not fix firmly and safely. (fig.8)
• Please ensure that 2 Safety Stopper Screws (supplied) are always fixed so that the Arca Swiss clamp will not fall off. As shown in (fig.9), please attach them to the safety stopper screw holes using the small hex key.

SHOULDER STRAP

Please attach the shoulder strap to the sling as described in Fig. 10.

PROTECTIVE COVER

As an accessory, [Protective Cover] comes with this lens to protect the attaching portion for the tripod socket, and improve the touch when the lens is held by hand.

To attach [Protective Cover] to the lens, first, the tripod socket must be removed. Then, as shown in Fig. 11, position the mark on [Protective Cover] to the same mark on the lens. After that, push the cover straight to the lens until it is attached.

To remove the cover from the lens, pull it straight in the opposite direction.

Please do not carry the lens holding the Protective Cover part while the cover is attached. It might cause a drop in the lens.

LENS HOOD

A bayonet-type detachable hood is provided with the lens. This lens hood helps to prevent flare and ghost images caused by extraneous light. Attach the hood and turn it clockwise until it stops rotating. (fig. 12)

• To place the lens and hood into the storage case, you must first remove the hood, and then replace it on the lens in the reverse position.

FILTER

• When using a polarizing filter with an AF camera, use the “circular” type.

BASIC CARE AND STORAGE

• Avoid any shocks or exposure to extreme high or low temperatures or 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 fingerprints from the lens elements. Clean by using a soft, moistened lens cloth or lens tissue.
• This lens is not waterproof. When using the lens in the rain or near water, prevent it from getting wet. It is often impractical to repair the internal mechanism, lens elements, and electric components damaged by water.
