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 stan-

dard 1.7/50 mm lens). Parallax error bet-

ween the lens and AF auxiliary light  limits

the close-up range with the AF auxiliary light

to approximately 0.7 m to 1 m.

If the automatic AF auxiliary light



is to be

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-

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!
