(Unit: m)

*The appropriate shooting distance (distance at which the appropriate exposure is available) is determined based on the combination of the ISO sensitivity setting and the aperture value on the camera when the mode dial is set to (FULL). (The values in "Wide Panel" line indicate the distance when the wide-angle panel is used.) Note that the minimum range that will give correct exposure is 0.7 meters.
