Operation
Assigning F-Stops
for a lens with non-linear iris ring markings:
• Use the OPEN and CLOSE keys ➪ photo to precisely
position the iris ring either at the largest or at the
smallest full F-Stop.
• Push the F-STOP key ➪ photo and keep it pushed down.
• Use the OPEN and CLOSE keys to set the iris ring to
each F-Stop. At each F-Stop push the CAL key ➪ photo
briefly.
Do not go to the end positions unless they represent a
full F-Stop change from the last F-Stop marking. The
NON LINEAR LED ➪ photo flashes while you read
the F-Stops. You can assign a minimum of two and a
maximum of twelve F-Stops.
• Release the F-STOP key. The NON-LINEAR LED ➪ photo
illuminates and thus indicates that the settings are valid.
If the NON-LINEAR LED stops blinking or does not
illuminate, the settings have not been memorized
properly. Then you must repeat the procedure.
Note: When assigning F-Stops on both linear and
non linear scales, use only full F-Stops!
The widest open F-Stop on many lenses, for
example, is not a full F-Stop.
The most common full F-Stops are:
1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, 45.
Verify Operation
• Run the camera without a magazine attached.
• Use your speed controller to change the speed from
24 to 48 fps. Watch the lens iris ring: it should open
up one stop.
