Correct Exposure Indication; Underexposure Warning In Ttl Flash Mode; Displays In The Camera Viewfinder; Flash Range Indication - Metz MECABLITZ 58 AF-1 digital Mode D'emploi

If a camera with a between-the-lens shutter (see the camera's operating
instructions) or FP high-speed synchronisation (see 18.4) is used, flash
sync speed is not controlled automatically. As a result, the flash can be
used at all shutter speeds. If you need the full light output of the flash
unit, you should not select a shutter speed that is any faster than 1/125
sec.

13. Correct exposure indication

The correct exposure indication „OK"
exposed in TTL flash mode (3D-TTL, D–TTL, i-TTL, etc.) or automatic flash mode.
If no „OK" exposure indication
underexposed. You will need to repeat the shot with the next smaller f-number
(for example, f/8 instead of f/11), or the distance to the subject or reflecting
surface (for example with bounce flash) will have to be reduced. Note the maxi-
mum flash range indicated on the display of the flash unit (see 16). For informa-
tion on the correct exposure indicator in the camera viewfinder, see also 15.

14. Underexposure warning in TTL flash mode

In certain modes („P" and „A", for example), some Group C, D and E Nikon
cameras (see Table 1) respond to an underexposed flash shot with a warning on
the display of the flash unit, indicating the amount of underexposure in
f-stops (see the camera's operating instructions).
If the correct exposure indication „OK"
after a flash shot is taken, or if the flash symbol blinks in the camera viewfinder,
then the display of the flash unit will briefly indicate the underexposure in f-stops
ranging from -0.3 EV to -3.0 EV in one-third increments.
In borderline instances the flash unit will not display an „OK", or the flash sym-
bol will blink in the camera viewfinder, even though the exposure is correct. In
this instance, no indication will appear on the LC display of the flash unit.
To enable underexposure warnings, the TTL mode (or 3D-TTL, D-TTL,
i-TTL, etc.) must be set on the flash unit.

15. Displays in the camera viewfinder

Examples of displays in the camera viewfinder:
A green arrow symbol lights up:
Command to switch on or use the flash unit.
A red arrow symbol lights up:
The flash unit is ready for firing.
A red arrow symbol remains lit up after the shot or goes out briefly:
The exposure was correct.
A red arrow symbol blinks after shooting:
The shot was underexposed.
For information applicable to the displays in the viewfinder of your
camera model, refer to the camera's operating instructions.

16. Flash range indication

The maximum flash range is indicated on the display panel of the flash unit. The
value indicated relates to subjects with a reflection factor of 25%, which applies
to most photographic situations. Strong deviations from this reflection factor, as
in the case of highly reflective or poorly reflective subjects, may affect the flash
range.
In TTL and automatic flash mode, the subject should be in the middle third of the
indicated range. This will give the automatic exposure control sufficient scope
for compensation.
To avoid overexposure, the minimum distance from the subject should be no less
than 10% of the indicated value. An adjustment can be made to a particular
photographic situation by changing the aperture setting, for example.
In manual flash mode M, the distance that must be maintained from the subject
for correct flash exposure is indicated. An adjustment to the photographic situa-
tion at hand can be achieved by, for example, changing the aperture setting on
the lens and by selecting either full light output or „P" for a partial light output
level.
