From Olympus:
In-Body Image Stabilization
The Olympus E-3 provides an in-body image stabilizer to greatly reduce the amount of camera shake, regardless of
the lens being used. This stabilizer can compensate for up to 5 EV steps, allowing the camera to be handheld in
some situations where a tripod would normally be required.
Choose from two accurate, high-speed image stabilization modes:
I.S. 1:
For general image stabilization, using both horizontal and vertical movements. (This can be ON for most
situations.)
I.S. 2:
Should be used when panning the camera in a horizontal direction to get a blurred background; in this
mode, image stabilization is applied only to vertical movements.
To enable the Image Stabilizer function, press the IS button while rotating the control dial to select the desired Image
Stabilizer mode.
Tips:
•
To view the effect of the Image Stabilizer while using Live View, hold down the IS button.
•
When using a lens with a built-in image stabilizer, turn OFF the image stabilizer either in the lens or in the
camera.
•
When shooting on a tripod or with high shutter speeds, the image stabilizer mode should be set to the OFF
position.
