In the auto flash mode, the flash unit’s sensor
measures the light reflected from the subject. The
flash is cut off as soon as sufficient light has been
emitted for correct exposure.
This eliminates the need to recalculate and readjust the
aperture each time the shooting distance is changed, pro-
vided that the subject remains within the indicated auto
flash range.
Setting procedure for automatic mode (fig. 4):
Example:
Flash-to-subject distance 5 m
Film speed ISO 100/21°
Taking into account the maximum effective range
,
a
flash-to-subject distance of 5m (see table at the back of
the unit) permits the use of the auto-working apertures f/4
or f/2
.
The maximum range with an auto-working aper-
ture of f/4 is 7 m, and with f/2 up to 14 m. The minimum
lighting distance is approx. 10% of the maximum effective
range.
The subject should be in the middle third of the
distance range. This gives the electronics suffi-
cient leeway for compensation should this prove
to be necessary.
