Example:
In our example on the left the main subject should be at a distance of 6.2 m
from the mecablitz.
10.1.5 Exceeding the capacity of maximum flash range indication
The mecablitz can indicate a maximum range of 199 m or 199 ft. In the
event of high ISO values (e.g. ISO 6400) and large aperture openings the
display range may be exceeded. This will be signalled by an arrow or trian-
gle after the indicated flash range.
10.1.6 Blanking out the maximum flash range indication
The mecablitz LC display does not indicate any distances when the flash
head is swivelled up or down out of its normal position.
10.1.7 Changing from meter to feet (m - ft)
The maximum flash range indicated by the mecablitz LC display can be ei-
ther in meter (m) or feet (ft). To change between the two, proceed in the fol-
lowing manner:
• Switch off the mecablitz by its main switch.
• Keep the Select key depressed.
• Switch on the mecablitz by its main switch.
• Release the Select key.
• The display changes and indicates only ft (or m).
• Press the “+” or”-” key.
• The maximum flash range is now given in ft (or m).
10.2 LC display illumination
Pressing the Mode, Select “+”, “-” or preselect key will activate the illumina-
tion of the mecablitz LC display panel. The illumination will be extinguished
when a flash is fired. If the shot was correctly exposed in TTL or automatic
flash mode, then the LC display illumination will automatically be activated
for the time the “o.k.” signal is displayed.
The settings on the mecablitz are not changed when the above keys
are pressed for the first time.

11. AF measuring beam
The AF measuring beam of the mecablitz can only be activated by
autofocus cameras that support the flash unit’s AF measuring beam.
The mecablitz must be fitted with an SCA 3002 adapter!
The AF measuring beam is activated by the camera electronics when the
ambient lighting conditions are insufficient for automatic focusing. The AF
beam projects a striped pattern on to the subject, and the camera uses this
pattern to focus automatically. The AF beam has a range of approx. 6 m to
9 m (with a 50 mm/f/1.7 standard lens). Parallax error between lens and
AF red light emitter limits the close-up range of the AF measuring beam to
approx. 0.7 m - 1 m. Low-speed zoom lenses can significantly curtail the
range of the AF measuring beam.
Various autofocus cameras only support their own built-in AF illumi-
nator (please also refer to the operating instructions for the given ca-
mera). In such an instance the AF measuring beam of the mecablitz
will not be activated.
Please note when selecting the camera’s autofocus mode that most
cameras only support the AF measuring beam in the operating mode
“Single AF” or “AF mode without continuous focusing”. The AF mea-
suring beam will not be activated in the “Servo AF” or “continuous
auto focusing” modes (see operating instructions for the given
camera).
Various cameras dispose of several AF sensors in their viewfinder.
However, the AF measuring beam of the mecablitz will only support the
camera’s central AF sensor. If your camera features several AF sensors
we recommend to activate only the camera’s central AF metering area
(please refer to the operating instructions for your camera).
If a decentral AF sensor is manually selected by the photographer, or auto-
matically by the camera, the emitter of the AF measuring beam of the meca-
blitz will not be activated. In such a situation, some cameras will use their
own built-in AF illuminator instead of the AF measuring beam (see operating
instructions for the given camera).
