fields, this means that the exposure can no longer regulated automatically. You can then
try to bring the pointer back into the black scale area by adjusting the diaphragm ring.
If this does not succeed, the automatic mechanism must be switched off and the
camera used in the usual (not automatic) way. When the exposure time drops to ,

timed exposures with a tripod are indicated.
When using filters, the automatic mechanism can still be used. To compensate for the
exposure meter, set the ASA scale on the top cover of the camera.
If you use for instance a filter that requires a value one full f-stop higher (filter factor 2),
the ASA scale on the top of the device should be reduced by a factor two. E.g. film
material initial setting 100 ASA, with filter: set to 50 ASA. Do not forget to reset the ASA
scale to the initial value when the filter is no longer used.
Basics:
Shutter speed and aperture stop can be individually controlled with the help of the
diaphragm control, despite being automatically regulated.
If the time for moving objects appears too long, a shorter time can be achieved by
opening the diaphragm.
If you value greater depth of field, the exposure time is continuously increased when the
diaphragm is closed. The individual f-stops have click stops; therefore only these numbers
should be set! Intermediate positions are to be avoided.
