5.5.6Ramp iris /

compensation shutter angle

The iris of the lens is continuously adjusted within the pre-set limit values (master value: Iris) over a pre-defined period of time after pressing the RAMP button (ramp, definition see Glossary).

The mirror shutter angle is automatically adjusted by the WRC-1 within the pre-defined limit values, to compensate the exposure.

The visible depth of field can be altered with this function.

In the main menu the automatically calculated shutter angle is shown in the first display line, and the current T-stop is shown in the second line.

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.

The ‘PROG’ symbol indicates that a time-controlled ramp function has been selected.
