5.7.12Ramp speed / compensation max. iris
The camera speed is continuously adjusted within the predefined limit values over a pre-defined period of time after the RAMP button is pressed in the camera run (master value: Camera speed).
The aperture of the lens is automatically adjusted by the WRC-1 within the pre-defined limit values, to compensate the exposure. If the adjustment range of the aperture is not sufficient for the given end values, the rest will be compensated for by the mirror shutter. In this case, the shutter angle proportion is evenly distributed over the entire compensation range.
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 first line of the main menu shows the symbol ’ ) ’ to indicate the shutter angle control, and the current T-stop, which is automatically calculated. The second line shows the current camera speed.
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.
