5.5.3Iris /

compensation shutter angle

The iris can be manually adjusted within the pre-defined end-stops of the handwheel (master value: Iris).

The exposure is automatically compensated for with the mirror shutter angle. The visible depth of field can be altered with this function.

The first line of the main menu shows the shutter angle, which is automatically calculated within the pre-defined limits. The second line shows the currently adjusted T-stop of the lens using the handwheel.

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.

Note

The following warnings may be displayed:

 

‘IRIS TBL’ – a valid iris table has not yet been

 

activated;

 

readings with ‘NO’ in the first display line

 

indicate that the selected function is currently

 

not available (examples: ‘NO IRIS’ although the

 

iris control is activated on the WRC-1, the iris

 

motor has not yet been connected. The connected

 

camera does not have an electronically adjustable

 

mirror shutter);

 

readings with ‘RANGE’ in the second display line

 

indicate that the adjustment range of a parameter

 

has been exceeded (example: the selected speed

 

cannot be attained with this camera);

 

readings with ‘OFF’ in the first display line

 

indicate that this function is deactivated on the

 

camera (example: shutter angle of the 435 is

 

set manually = ‘OFF ANGLE’).

 

Correct parameters must be set before the

 

camera is started!

Note:

To check the image in the viewfinder, the iris

 

can be opened completely by pressing the

 

OPEN button.

 

The iris remains open until the OPEN button is

 

released again.

 

This does not alter the programmed settings.

 

The OPEN button is without function while the

 

camera is running.

By pressing the SET button the currently set camera speed can be shown in the second display line.
