The handwheel is without function in the main menu.
Press the RAMP button when the camera is running to
start the ramp. The camera can be started, by pressing
the RUN button on the WMU-1.
The ramp can be reversed, by pressing the RAMP button
again: the ramp then reverses its direction until it reaches
the start value again. For best results wait until the end of
the ramp.
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 pro-
grammed settings. The OPEN button is without
function while the camera is running.
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.
