I :
Footage counter
This indicates the footage still
available,
both in
meters (lower
scale) and in feet (upper
scale).
Zero is automatically re-set when
the camera is unloaded
(11).
I'
:
Film wind locking
button
This
button
is to be
depressedwhen
achieving
superimposition
or
lap-
dissolves (refer to
p.
48)
CAUTION
:
Be
careful not
to depress this
button when

J :
Focussing-screen
retracting knob
This makes it possible to interpose or to retract a ground glass
screen between the eye and the lens. The advantage of the screen
is that it gives the operator an accurate appreciation of focus and the
depth or
lOCUS
available with the aperture used. It allows special
soft-focus effects.
The screen can be retracted by the actuating knob The image is
then only virtual and focussing is less
precise.
This method is to be
preferred when the operator attaches greater importance to luminous
viewing than to pinpoint focus (filming
at
infinity with high-sensitivity
film and a very small aperture, poorly-lit subjects, endoscopic pic-
tures, microcinematography, etc.
(12).
K:
Automatic
diaphragm
control system
(Reglomatlc)
The Reglomatic device ensures automatic diaphragm control
accord-
ing to the
amount
of light transmitted to the
photocell
by the
reflex
viewfinder;
it
acts
directly on the iris diaphragm of the lens (whence
its strength and
reliability,
and better definition of the resulting pic-
ture).
The automatic lens can be removed from the camera, and
replaced by non-automatic
lenses.
