Controlling the Camera Speed

With most lenses, the T-stops before the end-stops are not exact due to the tolerances involved. In order to avoid incorrect exposure, the adjusted iris range should not contain these values.

With the iris wide open a lens-related reduction in brightness towards the edge of the image may occur, looking like an incorrect exposure. The exact values are dependent on the lens type and must be determined with test shots.

•Press the MODE button in the main menu to enter the first submenu. The limit values for the left and right end-stop of the handwheel (minimum and maximum camera speed) can be defined.

The first display line shows the value for the left end-stop, the second line shows the value for the right end-stop.

•Press the SEL button for longer than 2 seconds.

The first digits in the first display line flash. 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 positions are set to ‘0’ by pressing the SET button.

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

•Press the MODE button to go to the next submenu. The limit values for the mirror shutter angle can be defined.

Both the mirror shutter angle and the aperture are automatically adjusted as an exposure compensation while the camera speed adjusted with the handwheel. One of the two limit values (minimum or maximum shutter angle, depending on the adjustment direction of the camera speed) 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 shutter angle display flashes in the first or second display line. This can now be set using the handwheel. The auto- matically calculated other limit value is shown in the other display line.

Press the SEL button again to switch to the next digit. The selected shutter angle is confirmed and the decimal is set to ‘0’ by pressing the SET button.

The minimum shutter angle corresponds to the selected minimum camera speed.
