Exposure adjustment

The exposure varies according to the lens iris.

The lens iris can be adjusted using the automatic iris or manual iris settings.

Lens iris selector switch

Iris ring

OAutomatic iris

Set the lens iris selector switch (IRIS) to “A.”

The iris is automatically adjusted to obtain the brightness which is commensurate with the subject.

$This unit’s automatic iris operation serves to measure the average brightness of the entire screen to control the iris. This means that the subject will tend to become all white or dark when a spotlight is directed on the subject or when the subject is shot under backlight conditions. Use the lens iris at the manual setting for lighting conditions such as these.

OManual iris

Set the lens iris selector switch (IRIS) to “M.”

Turn the iris ring and adjust the brightness.
