Tips on Using the Image Stabilizer 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 infinity position at normal temperature is the point at which the vertical line of the distance scale L mark is aligned with the distance index.
