Turning off the extended zoom mode (Fig. 35)
3
Continue depressing the “Select” key combina-
tion (= “Mode” key + “Zoom” key) until “Ex”
appears on the LC display.
4
Continue depressing the “Zoom” key until
“OFF” flashes on the LC display.
• The setting becomes instantly effective. The LC
display returns to its normal state after approx.
5 sec.
The “Ex” symbol for the extended zoom mode will
no longer be indicated on the mecablitz LC display!
5.8 AF measuring beam (Fig. 36)
The AF measuring beam is activated by the came-
ra electronics when the ambient lighting condi-
tions are insufficient for automatic focusing. The
AF beam emitter 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. 6m to 9m (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. 0.7m - 1 m.
The AF mode “Single-AF (S)” must be set on
the camera so that the AF measuring beam
can be activated by the camera (see the
camera’s operating instructions). Zoom
lenses with a small initial lens aperture may
significantly reduce the range of the AF
measuring beam!
The striped pattern of the AF measuring
beam only supports the camera’s central AF
sensor. When using cameras with several AF
sensors (e.g. F5, F100, F80) we recommend
to only activate the camera’s central AF
metering area (see the camera’s operating
instructions). If a decentral AF sensor is
manually selected by the photographer, or
automatically by the camera, then the emit-
ter of the AF measuring beam of the meca-
blitz will not be activated. In such instances
some cameras will use the AF illuminator
integrated in the camera (see operating
instructions of the camera).
