5.2 Range display
The flash range is displayed when using cameras that transmit ISO, lens focal
length and aperture data. For this a data exchange must have occurred bet-
ween the camera and flash unit, for example by tapping the shutter release.
The range can be displayed either in metres (m) or feet (ft) - see 9.7.
The flash range is not displayed when no data is transmitted from the
camera.
- when the reflector head is tilted out of its normal position (upwards,
downwards or sideways).
- the flash unit is working in remote flash operation (slave SL).
Range display in TTL flash modes
In the TTL flash modes ( , HSS ; see
7.1) the value for the maximum range of the
flash unit is displayed. The value indicated
relates to subjects with a reflection factor of
25%, which applies to most photographic
situations. Strong deviations from this reflec-
tion factor, as in the case of highly reflective
or poorly reflective subjects, may affect the flash range of the flash unit.
The subject ought to be in the area of approximately 40% to 70% of the value
displayed. This will give the automatic exposure control sufficient scope for com-
pensation. To avoid overexposure, the minimum distance should be no less than
10% of the indicated value! Adjustment to the photographic situation at hand
can be achieved by, for example, changing the aperture of the setting on the
lens.

Range display in manual flash mode M
In manual flash mode M, the distance that
must be maintained from the subject for cor-
rect flash exposure is indicated. Adjustment to
the photographic situation at hand can be achieved
by, for example, changing the aperture setting on the
lens or selecting a manual partial light output level (see
7.2).
Exceeding the display range
The flash unit can indicate flash ranges of up
to 199 m or 199 ft. This display range can be
exceeded in the case of high ISO values
(e.g., ISO 6400) and large aperture openings.
An arrow or triangle after the distance value indicates
that the display range has been exceeded.
6 Displays in the camera viewfinder
Examples for the camera viewfinder display:

Prompt indicating that the flash unit is to be switched on or used (by some
cameras).
Flash symbol is illuminated:
