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 lar-
ge 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:
Flash symbol flashes:
Prompt indicating that the flash unit is to be switched on or used (by some
cameras).
Flash symbol is illuminated:
The flash unit is ready for use (by some cameras)
For information applicable to the displays in the viewfinder of your
camera model, refer to the camera’s operating instructions.
7 Flash modes („Mode“)
Depending on the type of camera different TTL flash modes, manual flash mode
and high-speed synchronisation FP or HSS are available. Therefore, data trans-
fer between flash unit and camera is necessary before setting the flash mode,
e.g. by actuating the shutter release. The flash mode is set by using the „Mode“
ባ button.
7.1 TTL-flash modes
The TTL flash modes offer a very simple method of achieving very good flash
shots. In these modes, exposure readings are taken by a sensor built into the
camera, which measures the amount of light through the camera lens (TTL =
„Through The Lens“). Here the camera automatically determines the flash perfor-
mance required for a correct exposure of the shot. The advantage of the TTL
☞
flash modes is that all factors influencing exposure (filters, change of aperture
and focal length with zoom objectives, extensions for close-ups, etc.) are auto-
matically taken into account in adjusting the flash light.
If the shot was correctly lit, the correct exposure indication
ብ will flash „OK“ for
about 5 seconds (see 4.2).
Please note whether there are limitations for your camera in terms of film
sensitivity for TTL flash mode (for example, ISO 64 to ISO 1000; see
camera’s operating instructions)!
The TTL flash mode with measuring preflash is a further development of the stan-
dard TTL flash mode of analogue cameras. During the shot and before the actual
exposure, one or more almost indiscernible preflashes are executed by the flash.
The light reflected by the preflash is evaluated by the camera. According to the
evaluation, the subsequent flash exposure will be adjusted by the camera to suit
the situation (see the camera's operating manual).
Depending on the camera model, the preflashes precede the main flash
by such a short interval that they practically cannot be distinguished from
the main flash! The preflashes do not contribute to the lighting of the shot.
Setting procedure
• Press „Mode“ until „
“ flashes in the display.
The setting takes effect immediately. After about 5 seconds the display stops
flashing and the setting is saved automatically. „
“ appears in the display.
Automatic TTL Fill-in flash mode
The automatic TTL flash mode is activated by most cameras when the automatic
programme P is selected and by Vari or subject programmes during daylight
(see camera operating manual).
Fill-in flash mode overcomes troublesome shadows and produces a more balan-
ced exposure between subject and background with contre-jour shots. The
camera’s computer-controlled metering system sets the most suitable combination
of shutter speed, aperture and flash output.
