SIGMA 24-70 mm F2.8 DG DN Lenses
Thank you very much for purchasing a Sigma Lens. In order to get the maximum performance and enjoyment out of your Sigma lens, please read this instruction booklet thoroughly before you start to use the lens.
WARNING! 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.

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
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.
AFL BUTTON
It is possible to cancel autofocus by pressing the AFL button while the AF is
operating (AF lock / AF stop function) (fig.4).
- With some cameras, the AFL button does not work.
- some camera bodies can customize the function of the AFL button, so please check the details of the camera’s instruction manual.
ZOOMING
Rotate the Rubber grip on the zoom ring to the desired position.
ZOOM LOCK SWITCH
This lens is also equipped with a Zoom Lock Switch to eliminate the zoom creep
when the lens is tilted down. Please set the zooming ring to 24mm and set the
zoom lock switch to the “LOCK” position. (fig.5)
LENS HOOD
The lens hood helps to prevent flare and ghost images caused by bright
illumination from outside the picture area. Attach the hood and turn it
clockwise until it stops rotating (fig.6). To detach the hood, turn counter-
clockwise while pushing the button ♄ until it stops rotating (fig.7). When not
in use, the lens hood can be attached upside-down (fig.8).
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 an AF camera, use the “circular” type.
FLASH PHOTOGRAPHY
The camera’s built-in flash will cause barrel shadow if used with this lens.
For best results, please only use an external flash unit.
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 fingerprints from the lens elements. Clean by using a soft, moistened lens cloth or lens tissue.
- This lens benefits from a dust and splash-proof construction. Although this construction enables the lens to be used under light rain, it is not the same as being waterproof.
- Please pay attention to prevent a large amount of water from splashing on the lens, especially when using it by a waterside.
- It is often impractical to repair the internal mechanism, lens elements, and electric components if 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.
