5.6.2 Shutter angle /
compensation iris
The mirror shutter angle can be manually adjusted within
the pre-defined end-stops of the handwheel
(master value: Shutter angle).
The exposure is automatically compensated for with the
iris of the lens. The visible depth of field can be altered
with this function.
If the iris control is not available, the flashing warning
‘NO IRIS’ is displayed in the main menu. Connect the iris
control as described in chapter 4.1.2, calibrate the lens
and assign the T-stops as described in chapter 5.5.1!
The main menu shows in the first display line the currently
adjusted mirror shutter angle. The second display line
shows the currently adjusted T-stop of the lens, which is
automatically calculated within the pre-defined limit values.
The display shows full T-stops followed by the tenth of a
T-stop. Example: T-stop 2.8 plus half a T-stop is shown as
2.8_5. The tenths of a T-stop are linearly divided between
the two full T-stop positions.
