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 adjusted shutter
angle (if controlled by the WRC-1) can be shown in the
first display line.
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 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 left and right end-stop for the hand-
wheel (minimum and maximum aperture) 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 T-stop value in the first display line flashes.
The required value can now be adjusted using the
handwheel. Press the SEL button again to switch to the
next digit. The first digits are confirmed, and the
decimal is 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.
To define the values for the minimum and maximum
shutter angle (if controlled by the WRC-1), use the SEL
and SET buttons and the handwheel, as described above.
The first display line shows the value for the left end-stop,
the second line shows the value for the right end-stop.
