Af Auxiliary Light (Af-Beam) - Metz Mecablitz 64 AF-1 digital -Sony Bedienungsanleitung

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
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 stan-
dard 1.7/50 mm lens). Parallax error bet-
ween the lens and AF auxiliary light
the close-up range with the AF auxiliary light
to approximately 0.7 m to 1 m.
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 came-
k
ra'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 com-
pact cameras; see the camera's operating
instructions).
Low-speed zoom lenses can significantly cur-
tail the range of the AF auxiliary light!
