5 Information in Display
The Nikon cameras of the Groups B, C, D und E (see Table 1) transmit the set-
tings for ISO, lens focal length (mm) and aperture to the flash unit. It calculates
the maximum flash range from the settings and their guide number. Flash mode,
range, aperture and zoom position of the main reflector are displayed in the
display of the flash unit.
If the flash unit is operated without having received data from the camera (for
example, if the camera is switched off or with a camera from Group A), only
the flash mode selected, the zoom position of the main reflector and „Zoom“ is
displayed. The displays for aperture and range only occur once the flash unit
has received the data required from the camera.
Displays for aperture and range only occur with cameras from Groups B,
C, D & E (see Table 1) if these are operated with an AF lens or a lens with
CPU !
Display illumination
Every time a button on the flash unit is pressed, the flash display illumination is
activated for 10 seconds. When a flash is fired via the camera or the hand
release
ቤ on the flash unit, the display illumination is switched off.
5.1 Display of the flash mode
The flash mode set appears in the display.
Depending on the camera model or camera
group (see Table 1), different displays are
possible in this connection for the various
TTL flash modes supported (for example,
, BL, , BL) and the
manual flash mode M, see 7).

5.2 Range display
When using cameras from Groups B, C, D and E and a lens with CPU, the ran-
ge is indicated in the display. 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.
There is no range display with cameras from Group A, or
- when using lenses without CPU (e.g. manual focus lens).
- 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 (
, BL, ,
BL; see 7.1) the value for the maximum
range of the flash unit is displayed. The value indica-
ted 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 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.
