13.3 Slow synchronisation

When the flash unit is operated with an SCA adapter it is possible with many

cameras to select slow synchronisation (SLOW). Here the camera sets shutter

intervals that are adapted to the surrounding light. During darkness this helps

to emphasise the picture background. The setting is made on the camera. For

more details, see the operating instructions of the camera and SCA adapter.

14. Maximum range display

The range display can as required be made in metres (m) or feet (ft) –

see 8.7.

If the reflector is swivelled, and in Metz remote mode, no maximum range

display is shown!

14.1 Automatic adjustment of the working range display

Various cameras transmit the flash parameters for light sensitivity ISO, focal

length of the lens (mm), aperture and exposure correction to the flash unit.

The flash unit then adapts its settings automatically. The maximum flash ran-

ge is calculated and shown in the display on the basis of the flash parame-

ters and the guide numbers.

For an automatic adjustment of the maximum flash range indication the flash

unit must be equipped with an SCA adapter of the SCA 3002 system. In

addition, the camera must transmit the flash parameters required to the flash

unit (on this see the operating instructions of the SCA adapter and camera)!

An exchange of data must take place between the camera and flash unit

(e.g. by lightly tapping the camera release button)!

14.2 Manual adjustment of the maximum range display

If the flash unit is used with an SCA adapter from the SCA 300 system or the

standard foot 301 or a camera that does not transmit the flash parameters,

the flash parameter(s) for zoom position, light sensitivity ISO and aperture

value must be set manually for a reliable maximum flash range indication.

14.3 Maximum range displays in TTL and automatic flash mode

The value for the maximum range of the flash is shown in the display of the

flash unit. The value shown refers to a subject reflection factor of 25% of the

subject, which applies to most shooting situations. Wide deviations of the

subject reflection factor, e.g. in the case of highly or poorly reflective objects,

can influence the maximum flash range.

While shooting, it is important to pay attention to the maximum flash range

indication in the display of the flash unit. The subject should be in the centre

third of the value shown. This provides the automatic exposure system with

enough room for manoeuvre for equalisation. The minimum distance to the

subject should not be less than 10% of the value shown in order to avoid

over-exposure! The adjustment to the particular shooting situation can be

achieved by changing the aperture on the lens.

14.4 Maximum range display in manual flash mode M

The distance value is shown in the display of the flash unit, which must be

maintained for a correct flash exposure. The adjustment to the specific shoo-

ting situation can be achieved by changing the aperture on the lens and by

choosing between full light output and a partial light output “P”.

14.5 Cancelling the maximum range display

If the reflector head is swivelled from its normal position or the flash unit is

working in Metz remote mode, no distance indication appears in the display!

15. Pre-flash function against “red-eye effect”

The “red-eye effect” occurs when the people to be photographed look more

or less directly into the camera, the ambient light is dark and the flash unit is

located close to the camera. The flash unit then lights up the background of

the eye through the pupil.

One or several pre-flashes lead to the pupils of the subject closing further

and hence reducing the red-eye effect. The function is set on the camera (see

operating instructions of camera and SCA adapter).
