  • Be sure to turn off the OS switch to the OFF position, before attaching or detaching the lens to the camera.
  • The Optical Stabilizer 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, you could damage the lens.
  • Although the viewfinder image may appear to shake immediately after
    shooting and at the start of the flash charge cycle of the built-in flash of the camera etc., it will not cause any effect on pictures.
  • If the camera power is turned off or the lens is detached while the Optical Stabilizer function is in operation, the lens may emit a chattering noise, but this is not a malfunction.
  • For Canon mount, the Optical Stabilizer (OS) function will not work with film SLR cameras except the Canon EOS-1V.

For further information, please refer to the SIGMA Optimization Pro “Help” menu.

  • When SIGMA TELE CONVERTER TC-1401 is attached to cameras that are compatible with AF at F8, it is possible to shoot with AF. (Focus accuracy is not ensured when the focal length scale is more than 200mm.)


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.9)Sigma-100-400mm-DG-OS-HSM-Lens-for-Canon-Instruction-Manual-9

  • In order 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.


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


  • 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.
