pears on the display. The setting becomes instantly effective. The LC display
returns to its normal state after approx. 5 sec.
Or:
• Briefly turn off the mecablitz by its main switch. When the flash unit is
turned on again the mecablitz display will indicate "Auto Zoom".

5.7.4 Extended zoom mode

The extended zoom mode (Ex) reduces the focal length setting of the meca-
blitz by one step as compared to the focal length of the camera lens! The
resulting wider light coverage inside rooms provides additional stray light
(reflections) to achieve a softer flash illumination.
Example of extended zoom mode:
The focal length set on the camera lens is 35 mm. The extended zoom mode
sets a 28 mm reflector position on the mecablitz but 35 mm continues to be
indicated on the LC display!
The extended zoom mode is only possible in the "Auto Zoom" mode with Group
A cameras as listed in Table 1 and CPU lenses with focal lengths as of 35 mm
(28 mm for 44 AF-4N).
Since the initital position of the zoom reflector is 28 mm (24 mm for 44 AF-4N),
a focal length of less than 35 mm (28 mm for 44 AF-4N) will cause "28" mm
("24" mm for 44 AF-4N) to flash on the LC display thereby warning the user that
the required reflector position for the extended zoom mode cannot be set.
Shots taken with a 28 mm (24 mm for 44 AF -4N) to 35 mm focal
length setting will be correctly illuminated right out to the image cor-
ners by the mecablitz also in extended zoom mode!
Turning on the extended zoom mode
• Continue depressing the "Select" key combination (= "Mode" key +
"Zoom" key) until "Ex" appears on the LC display.
• Continue depressing the "Zoom" key until "On" flashes on the LC display.
• The setting becomes instantly effective. The LC display returns to its normal
state after approx. 5 sec.
After the setting procedure, the "Ex" symbol for the extended zoom mode will
continue to be indicated on the mecablitz LC display!
Please note that the wider illumination coverage in extended zoom
mode results in a diminished maximum flash range!
Turning off the extended zoom mode
• Continue depressing the "Select" key combination (= "Mode" key +
"Zoom" key) until "Ex" appears on the LC display.
• 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

The AF measuring beam is activated by the camera electronics when the
ambient lighting conditions 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.
6 m to 9 m (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. 0.7 m - 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!
