indicates a 10 foot maximum range in the Purple Mode, which corresponds to
f11. You decide to use this mode. While this selection will give you proper
exposure with significant depth of field, it will use most of the energy in the
flash capacitor. As a result, the batteries must work harder and longer to
re-energize, which causes longer recycling time between flashes and fewer
flashes per set of batteries.
The best auto mode for fastest recycling time and most flashes (but limited
depth of field) is the yellow mode. (The next best is RED, then BLUE, etc.) It
provides an enormous auto exposure range to 60 feet (up to 70 feet with the
Flash Head in the TELE position). And because you must use a wider lens
opening, it takes less light for exposure. The auto sensor shuts the light off
sooner, so a limited amount of energy from the capacitor is used and the
thyristor circuit holds the excess energy inside it. The batteries aren’t depleted
as quickly, so you get faster recycling time and more flashes.
Please note that while the f/number changes with the speed of the film / ISO,
the auto range remains constant.
On-Camera Direct Flash
This method of operation with your Cactus KF-36 allows you to photograph
subjects at maximum distances from the flash while still maintaining automatic
flash exposure control.
Set your camera to the correct shutter speed for electronic flash. (Refer to
your camera instructions.)
If you have not already done so, set the Zoom / Bounce Head to the
NORM position, and set the ISO you are using on the Calculator Dial
(page 8). The four colored wedges on the Calculator Dial now line up
below the four automatic f-stops you are using.
Select any one of the four automatic mode color wedges and
corresponding f-stops on the Calculator Dial that provides the automatic
operating range or depth of field you desire. Generally speaking, the
yellow mode will provide the fastest recycling time and the most number
of flashes. If your lens doesn’t have an f-stop that corresponds to the
yellow mode, use the red mode instead.
Turn the Mode Selector Dial on the Vari Sensor Module until the color
that corresponds to the f-stop you selected in step 3 above appears in the
Mode Selector Window (25) on the side of the Module.
Set your camera lens to the auto f-stop you selected in step 3.
Set the Flash Head to the 0
ﾟ
tilt (straight ahead) position.
