11 – OPERATING THE COMPACT MK2
After connecting the Iris Control Unit to the Mk2, switch
the Main switch on.
The LED
[E]
shortly lights up. Now the following proce-
dure should be pursued:
1. Swing away the Iris Control Unit from the lens
(decoupling of gear wheel).
2. Put lens aperture to “8”.
3. Calibrate the Iris Control Unit by pressing the
Inching knob
[G]
.
4. Fence the gear wheel into the aperture gear rim.
5. Turn the gear wheel electrically with the help of the
small Flip switch
[D]
until aperture “8” has been
reached exactly!
6. Operate Set switch
[F]
– for safety reasons only
accessible through a 2 mm hole – with the help of a
sharp object (e.g. screwdriver, toothpick, pen).
7. The red LED
[E]
lights up.
8. Turn the gear wheel electrically with the help of the
small Flip switch
[D]
until an aperture value 3 steps
higher or lower (2.8 or 22, depending on the lens)
has been reached exactly!
9. Press Set switch
[F]
again.
10. Red LED
[E]
fades.
11. Adjust camera to either of the two desired frame
rates (FPS 1 or 2).
12. Turn the gear wheel electrically with the help of the
small lever
[D]
to the desired (measured) aperture
value.
Example:
fps 1 = 24 fps
Aperture 5.6
or fps 2 = 48 fps
Aperture 4.0
▲
Check
When setting a different frame rate with the FPS
Input Unit on the Mk2, the aperture is automatically
adjusted. This check is done when the camera is
STAND-BY. Now the Iris Control Unit is calibrated
with the lens in use. This setting remains stored until
the next calibration, even when the devices are
removed and mounted again or are separated from
the power supply.
Caution!
The Iris Control Unit only works with modern
lenses where the aperture scale is linear!
