Controlling the Iris

Press the MODE button in the main menu to enter the first submenu. The limit values for the minimum and maximum aperture can be defined.

The first display line shows the start value of the aperture, and the second line the value at the end of the ramp.

Press the SEL button for longer than 2 seconds. The T-stop value in the first display line flashes. The required value can now be set using the handwheel. Press the SEL button again to switch to the next digit. The first digits are confirmed, and the decimal is set to ‘0’ by pressing the SET button.

The values in the second display line can be set accordingly.

If the compensation range available with the shutter angle is exceeded, the warning ‘ANGLE RANGE’ flashes on the display after returning to the main menu. The settings for the iris or the shutter angle must be corrected accordingly! The camera can still be started for test purposes in spite of the flashing warning. However, the exposure may be incorrect!

Press the MODE button to go to the next submenu. The limit values for the shutter angle can be defined. The shutter angle is automatically adjusted by the WRC-1 to compensate the exposure, while the iris is being adjusted. One of the two limit values (minimum or maximum shutter angle, depending on the adjustment direction of the iris) can be defined; the other limit value is automatically calculated by the WRC-1.

Press the SEL button for longer than 2 seconds. Depending on the definable limit value, the first digits flash in the first or second display line. These can now be set using the handwheel. The automatically calculated other limit value is shown in the other display line. Press the SEL button again to switch to the next digit. The first digits are confirmed, and the decimal is automatically set to ‘0’, by pressing the SET button. The minimum shutter angle corresponds to the selected full aperture (smallest T-stop number).
