Using the Image Stabilizer on the EF 400mm f/4 DO IS USM lens


Image Stabilizer

You can use the image stabilizer in AF or MF mode.
Set the STABILIZER switch to ON.
  • If you are not going to use the image stabilizer function, set the switch to OFF.
Select an Image Stabilizer mode.
  • MODE 1: Corrects vibrations in all directions. It is mainly effective for shooting still subjects.
  • MODE 2: Corrects vertical camera shake during following shots in a horizontal direction, and corrects horizontal camera shake during following shots in a vertical direction.
When you press the shutter button halfway, the Image Stabilizer will start operating.
  • Make sure the image in the viewfinder is stable, then press the shutter button the rest of the way down to take the picture.

Tips on Using the Image Stabilizer

The image stabilizer for this lens is effective for hand-held shots in the following conditions.

  • In semi-darkened areas such as indoors or outdoors at night.
  • In locations where flash photography is prohibited, such as art museums and theater stages.
  • In situations where your footing is uncertain.
  • In situations where fast shutter settings cannot be used.

  • When panning subjects in motion.
  • The image Stabilizer cannot compensate for a blurred shot caused by a subject that moved.
  • Set the STABILIZER switch to OFF when you are taking pictures using the Bulb setting (long exposures). If the STABILIZER switch is set to ON, the image stabilizer function may introduce errors.
  • The Image Stabilizer might not be effective in the following cases:
    • You shoot while riding on a bumpy road.
    • You move the camera dramatically for a panning shot in MODE 1.
    • You shoot using techniques other than following shots in Mode 2.
  • The Image Stabilizer consumes more power than normal shooting, resulting in fewer shots and a shorter movie shooting time.
  • The image stabilizer operates for about two seconds even when your finger is off the shutter button.
    Do not remove the lens while the stabilizer is in operation. This will cause a malfunction.
  • With Extender EF2x II attached to the lens, the Image Stabilizer will work with the following cameras: EOS-1Ds Mark III, EOS-1Ds Mark II, EOS-1Ds, EOS-1D Mark IV, EOS-1D Mark III, EOS-1D Mark II N, EOS-1D Mark II, EOS-1D, 40D, 30D, 20D, 20Da, 10D, 5D, DIGITAL REBEL XSi/450D, DIGITAL REBEL XTi/400D DIGITAL, DIGITAL REBEL XT/350D DIGITAL, DIGITAL REBEL/300D DIGITAL, D60, D30, EOS DCS1, DCS3, D2000, D6000, EOS-1V/HS, EOS-1N/DP/HS/RS, 3, ELAN 7E/ELAN 7/30/33, ELAN 7NE/ELAN 7N/30V/33V, ELAN II/ELAN IIE/50/50E, REBEL X/REBEL XS/500, REBEL G/500N, REBEL 2000/300, REBEL Ti/300V, REBEL T2/300X, REBEL K2/3000V, IX, IX Lite/IX7, 3000/88, 5000/888
  • With the EOS-1V/HS, 3, ELAN 7E/ELAN 7/30/33, ELAN 7NE/ELAN 7N/30V/33V, ELAN II/ELAN II E/50/50E, REBEL 2000/300, IX, IX Lite/IX7, and D30, the Image Stabilizer will not work during self-timer operation.
  • When you use a tripod, the Image Stabilizer should be turned off to save battery power.
  • The stabilizer is equally effective for hand-held photography and photography with a monopod. The Image Stabilizer effect may be reduced, however, depending on the shooting environment.
  • The Image Stabilizer also operates when the lens is used with extension tube EF12 II or EF25 II or the extender EF1.4x II or EF2x II.
  • Pictures may look distorted after being taken depending on the camera, but this doesn't affect shooting.
  • If you set the camera's Custom Function to change the assigned button to operate the AF, the Image Stabilizer will operate when you press the newly assigned AF button.
