5. Image Stabilizer This function provides image stabilization appropriate for shooting conditions (such as shooting still subjects and panning shots). Set the image stabilizer switch to ON when you want to use the Image Stabilizer. zzSet the image stabilizer switch to OFF when you are not going to use the Image Stabilizer. zzThe Image Stabilizer cannot compensate for a blurred shot caused by a subject that moved. zzThe Image Stabilizer may not be fully effective if you shoot from a violently shaking vehicle or other transportation. zzThe Image Stabilizer operates for about two seconds after turning off the camera. Do not detach the lens during that time. This may cause the lens to malfunction. zzWhen using a tripod, it is recommended that you set the image stabilizer switch to OFF. zzEven with a monopod, the Image Stabilizer will be as effective as during hand-held shooting. However, depending on the shooting conditions, there are cases in which the Image Stabilizer effect may be less effective. zzWhen shooting a still subject, it compensates for camera shake in all directions. zzIt compensates for vertical camera shake during panning shots in a horizontal direction, and compensates for horizontal camera shake during panning shots in a vertical direction.
