12 Automatic AF measuring beam

The automatic AF measuring beam
camera when the ambient lighting conditions become inadequate for automatic
focusing. It projects onto the subject a striped pattern that the camera can use to
focus. Depending on the camera's activated AF sensor, the AF beam has a ran-
ge of approximately 6 m to 9 m (with a standard 1.7/50 mm lens). The maxi-
mum flash range is reached with the camera's central AF sensor. Parallax error
between lens and AF measuring beam limits the close-up range with the
AF measuring beam to approximately 0.7 m to 1 m.
If the automatic AF measuring beam
the „single AF (S)" autofocus mode must be set on the camera and the
flash unit must indicate flash readiness. Some camera models support
only the camera's internal AF measuring beam. In this case, the automa-
tic AF measuring beam of the flash unit is not activated (as in the case of
compact cameras; see the camera's operating instructions).
Low-speed zoom lenses can significantly curtail the range of the AF measuring
beam!
Some cameras support the AF measuring beam in the flash unit only with the
camera's central AF sensor. If a peripheral AF sensor is selected, then the AF
measuring beam will not be activated in the flash unit!

13 Triggering control (auto-flash)

On some cameras the flash will not be fired when the prevailing light is suffi-
cient for an exposure. When the camera shutter release is depressed, no flash
exposure is triggered.
In various cameras the triggering control only works in the full program mode
or „P" program or must be activated on the camera (see camera operating
instructions).
