Image Stabilizer

4 step Image Stabilizer (IS) extends low light options to previously unimaginable levels. Photographers normally shooting handheld at 1/250 sec can switch on IS to obtain a similarly steady and blur-free result with a shutter speed of just 1/15 second.

IS reduces dramatically the image blur caused by camera shake. Gyro sensors detect unwanted vibrations, triggering the corresponding movement of a correcting lens group perpendicular to the optical axis. This alters the light path, returning the image to its correct position on the sensor or film plane.

For shooting immobile subjects, Mode 1 corrects for movement in the image along both the horizontal and vertical axes. For shooting while panning horizontally to follow a moving subject, Mode 2 turns off vertical correction and prevents the effect of dragging the subject back through the frame.

IS switches off automatically when the camera is mounted on a tripod, thus preventing feedback loops between the IS sensor and internal motor vibrations.
