Tips on Using Image Stabilization OO The Image Stabilizer cannot compensate for a blurred shot caused by a subject that moved. OO The Image Stabilizer might not be fully effective in the following conditions: • Large shake or fast vibration • Panning in MODE 1 OO Setting the STABILIZER switch to ON consumes more power than when OFF. OO Vibration such as during transport may unlock the Image Stabilizer and cause rattling, but this is not breakage and will have no effect on usage. This will be rectified once the lens has been mounted on the camera. OO Although image stabilization will operate when using a tripod, depending on the kind of tripod and shooting conditions, sometimes it may be better to turn off the Image Stabilizer. OO Although image stabilization will operate when using a monopod, depending on the shooting conditions, sometimes the Image Stabilizer might not be fully effective. OO Setting the STABILIZER switch to OFF is recommended when you are taking pictures using the Bulb setting (long exposures). If the STABILIZER switch is set to ON, the Image Stabilizer may introduce errors. OO 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. OO Depending on the camera there may be image shake, such as after releasing the shutter. However, this does not affect shooting. OO If you set the camera's Custom Function to change the AF button assignment, the Image Stabilizer will operate when you press the newly assigned AF button. ENG-18
