Example:
In this example the maximum flash range extends from
0.6 m to 6.2 m. Ideally, the subject should be located
within a distance range of approx. 2.5 m and 4.3 m.
7.4.2 Maximum flash range indication in
the manual flash modes M and MLo
(Fig. 18a)
The mecablitz LC display indicates the distance to
be maintained for correct exposure of the subject.
Adaptation to the given photographic situation is
achieved by changing the aperture setting on the
lens and selecting either „M“ for full light output
or „MLo“ for partial light output (see 4.2).
Example:
This example shows that the principal subject should
be at a distance of 6.2 m from the mecablitz.
7.4.3 Exceeding the display range (Fig. 19)
The mecablitz can indicate a maximum range of
199 m or 199 ft. This display range can be
exceeded in the event of high ISO values (e.g.
ISO 6400) and large aperture openings. An
arrow or triangle after the distance value in-
dicates that the display range has been exceeded.
7.4.4 Blanking out the maximum flash
range display (Fig. 20)
The mecablitz LC display does not indicate any
distances when the reflector head is swivelled up
or down out of its normal position!
7.4.5 Guide number indication with a
manual-focus lens
Some manual-focus lenses do not transmit to the
camera any information concerning focal length
and aperture setting. In the event that such a lens
is used, then the mecablitz will only receive infor-
mation regarding the ISO film speed from the
camera. The position of the zoom reflector must
then be set manually (see 7.6.2). In this case the
LC display of the mecablitz will indicate the guide
number for the given setting instead of a distance
range (in our example: guide number 34). The
maximum flash range is now the result of the fol-
lowing formula:
guide number
Maximum flash range =
aperture
