Af Auxiliary Light (Af Beam) - Metz mecablitz 64 AF-1 digital Mode D'emploi

11.6 AF auxiliary light (AF BEAM)

If the AF metering system of a digital AF reflex
camera is unable to focus due to insufficient
ambient lighting, the camera activates the
AF auxiliary light built into the flash unit.
This projects a stripe pattern onto the subject
which the camera uses to focus.
With the "AF-BEAM" function, the AF auxiliary
light can be switched on or off.
The range is approx. 6 m... 9 m (with a
standard 1.7/50 mm lens). Parallax error
between the lens and AF auxiliary light
limits the close-up range with the AF auxiliary
light to approximately 0.7m to 1m.
If the automatic AF auxiliary light
activated by the camera, the "Single-AF (S-AF)"
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 auxiliary light. In this
case, the automatic AF auxiliary light of the
flash unit is not activated (as in the case of
compact cameras; see the camera's opera-
ting instructions)!
Low-speed zoom lenses can significantly
curtail the range of the AF auxiliary light!
Some cameras support the AF auxiliary light
in the flash unit only with the camera's
central AF sensor. If a peripheral AF sensor is
selected, then the AF auxiliary light
not be activated in the flash unit!
