Shooting Manually
Direct Flash
If you wish to use your flash in Manual Mode (for taking pictures beyond the automatic
flash range or when using multiple flash lighting), proceed as follows:
Set the Mode Selector Dial (24) to the manual “M” position.
Estimate the distance from the flash to the subject. The easiest way to do
this is to focus your camera and refer to the distance indicated on the
camera lens barrel after focusing.
Find the flash-to-subject distance on the Calculator Dial Distance Scale
and set your lens to the f-stop indicated above that distance. (Disregard
the colored wedges on the Dial when shooting in the manual mode.)
Example: If you are 40 feet from your subject and are using the NORM
flash head position and ISO 100, set your lens f-stop to f2.8. (photo A.)
Slide the On – Off Switch to the RED “ON” position. Check camera focus.
Take the picture when the green Ready Light glows.
Caution: For rapid sequence flash pictures in the manual mode, you may
fire your Cactus KF-36 as soon as the green Ready Light glows.
However, to prevent possible damage, avoid a continuous series of more
than 25 flashes and allow the unit to “rest” for 4 minutes between series.
If you want to extend or retract your Zoom / Bounce Head to the TELE or
WIDE setting, it will affect your f-stop and / or operating range, and you should
recheck your Calculator Dial for new information.
Note: If you wish to mathematically calculate your f-stops, divide Guide
Number by flash-to-subject distance. Remember that Guide Number will
change with extension or retraction of the Zoom / Bounce Head. See
Manual Operation Guide Numbers (page 20) for a complete listing of
Guide Numbers for various films speeds (ASA /ISO and DIN) for each of
the three zoom head positions and Super Wide Angle Flash Lens.
