16.2 Second curtain synchronisation (REAR, 2nd curtain, SLOW2)

Some cameras offer the option of second-curtain synchronisation (2nd curtain

mode), in which the flash unit is not triggered until the end of the exposure

time. This is particularly advantageous when used with slow shutter speeds (slo-

wer than 1/30 sec.) and moving subjects that have their own source of light.

With second-curtain synchronisation, a moving light

source will trail a light streak instead of building one

up ahead of itself, as it does when the flash is syn-

chronised with the first shutter curtain. Second-curtain

synchronisation thus produces a more „natural“ image

of the photographic situation when there are moving

light sources. Depending on its operating mode, the

camera sets shutter speeds slower than its sync speed.
On some cameras, the REAR function is not possible in certain operating modes

(e.g., certain vari- or subject programmes). In that case, the REAR mode cannot

be selected, or the REAR function is automatically cancelled or ignored (see the

camera's operating instructions).
Adjusting the setting

• Press the

button repeatedly until "Select"

appears on the display.

• Use the

and

buttons to select "REAR" (2nd

curtain synchronisation) from the menu. The selected

menu option is indicated by a dark bar.

• Press the

button and confirm the setting of the

special function.

Set

Sel

• Use the

and

buttons to make the desired

settings. The setting is effective immediately.

– In the "REAR ON" setting, synchronization is

on the 2nd shutter curtain.

– In the "REAR OFF" setting synchronisation is

set to normal.

• Press

repeatedly to return the display to normal.

If the

button is not pressed, the display will switch back to normal auto-

matically after approximately 5 seconds.

If the 2nd shutter curtain synchronisation is

activated "REAR" appears on the display!

The REAR mode is automatically cancelled as soon as the flash unit is
switched to contrast or the High-Speed flash mode P-TTL-HSS.
Use a tripod to avoid camera shake with slow shutter speeds!

16.3 Slow synchronisation / SLOW

Various cameras feature slow flash synchronisation in certain modes. This set-

ting will give added prominence to the background at lower ambient light

levels. This is achieved by matching the shutter speed to the ambient light.

Accordingly, shutter speeds that are slower than the flash sync speed are auto-

matically adjusted by the camera. Some cameras automatically activate SLOW

synchronisation in connection with certain camera programs (e.g. „Av“ apertu-

re priority, night shots program, etc.). No settings are made on the flash unit nor

is there any display for this mode.

Use a tripod to avoid camera shake with slow shutter speeds!
