Focussing
If you have a "Fix-Focus" lens, the shortest distance at which pictures will be
sharp is shown on the scale opposite each diagram setting (f-stop). If you have a
lens fitted with the “Visifocus" or "Compass" depth-of-focus scale, you will had
it most convenient to begin by setting the diaphragm, and then to place the “∞"
sign opposite the last orange dot on the " Visifocus " scale, or the end of the
white line on the “Compass" scale. The other end of the dotted scale or line then
shows the shortest distance at which subjects will still be sharply focussed (for
instance 0,60 m in the case of a 12.5 mm lens with the diaphragm set to f : 8).
When shooting very near close-ups, the lens must be focussed to the exact
distance between the subject and the him itself.
This distance must be reckoned from the film plane (see Fig. 2).

To alter the filming speed
Adjust the speed control according to the effect which it is desired to obtain. The
normal filming rate is 16 frames per second. This corresponds to the rate at
which silent projectors are normally run.
normal filming rate is 16 frames per second. This corresponds to the rate at
which silent projectors are normally run.
Note: Do not forget that altering the filming speed also alters the rate of
exposure of the film. Thus this rate, which amounts to 1/35th second at 16
frames per second, will be doubled at 8 frames per second, whereas at 64 frames
per second it will be reduced to a quarter of its normal value, i.e.
to l/l40th second. In such cases the diaphragm setting should be readjusted to
compensate for this variation.

E.g.: filming rate 16 frames per second, set diaphragm to 5,6
filming rate 3 frames per second, set diaphragm to 8
filming rate 32 frames per second, set diaphragm to 4
filming rate 3 frames per second, set diaphragm to 8
filming rate 32 frames per second, set diaphragm to 4
