Macro shots
flash you use (number of flashes
between two recharges, strength of
flash, etc.). Do not forget that a scene
lasting only 5 seconds on projection
requires 90 frames at the rate of
18 frames/second.
Take the following precautions:
mount the camera on a steady sup-
port (tripod);
determine the correct aperture based
on the electronic flash unit and its
distance from the subject by means
. of the following formula:
diaphragm
=
guide number
distance in feet
Example: guide number 80
distance 10ft.
~ =
f/8
10
Lock the diaphragm at the aperture
determined by the formula.
N.B.: since the optical system in Su-
per 8 cameras has a greater light loss
than in still cameras, it is recom-
mended to use a film sensitivity half
the rated speed (ASA 20 instead of 40)
when determining the guide number.

To mount the electronic flash on the
camera, use the flash-shoe provided
for this purpose, which slides into the
slot located on top of the camera and
intended above all for holding the
key for retracting the conversion filter.
We recommend you to make a few
test runs before filming an important
sequence with electronic flash for the
first time.
Synchro-sound filming
The contact used for the synchroni-
zation of an electronic flash gives off
one impulse per frame and can also
be used for connecting a tape-re-
corder for synchro-sound recording.
Your photographic dealer will gladly
give you information concerning the
different possibilities.

After pressing the macro button, the
zoom knob can be turned either by
hand or with the power zoom motor
into the macro range, thereby extend-
ing the focusing range from infinity
down to where the lens touches the
subject, covering an area approxi-
mately an inch in size.
When the zoom knob is in the Macro
zone, the lens is set to wide-angle
position, which ensures greater depth
of field and good picture steadiness
even if you film holding the camera
in your hand.
