3. Automatic flash mode
In the auto flash mode, the flash unit’s sensor ቯ
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°
ᕢ
Focal length, e.g. 50mm (35mm format)
The mecablitz is used without a W or T attach-
ment
ቩ in place.
Taking into account the maximum effective range
ᕡ, 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
ᕣ. 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 pro-
ve to be necessary.
• Set the operating mode selector
ቧ
to the required auto-
working aperture.
For the shortest-possible depth-of-field (as is required in
portraiture) the use of an auto-working aperture of f/2 is
recommended. For group shots with a number of people
standing behind each other, set an auto-working aperture
of f/4 to extend the depth-of-field.
• Turn on the flash unit with the main switch
ቤ
.
• Switch the SLAVE function selector ቮ to position 0!.
• Set the camera to flash synch speed or a slower speed.
• Await flash readiness which is indicated by the green
flash-ready light
ቢ
.
Caution with zoom lenses!
Due to their design they can cause a loss of
light in the order of up to one f-stop. Further-
more, the effective aperture can also vary,
depending upon the adjusted focal length. This
can be compensated by correcting the apertu-
re on the flashgun manually!
