FLASH CONTROL
The settings and functions described in the following sections only
apply to settings and functions available in this camera and in
system-compatible flash units.
SYNC POINT
Flash exposures are lit by two light sources:
– ambient light
– flash
Any subject elements lit primarily by the flash will almost always be
rendered in perfect focus by the short burst of light, provided the
focus is set correctly. All other subject elements in the same frame
lit by ambient light or lit from within will be rendered with varying
degrees of sharpness. Whether or not these subject elements will
be rendered in sharp focus or blurred, as well as the degree of
"blurriness" depends on two interdependent factors:
– the shutter speeds
– the speed of movement of the subject elements or camera
during recording
The longer the shutter speed and the faster the motion, the greater
the difference between the two superimposed partial images.
A flash is usually fired at the start of exposure (
Start of Exp. Start of Exp.
), right
after the first shutter curtain has completely opened the image
window. This may result in apparent contradictions, e.g. the picture
of a vehicle being overtaken by its own light trail. Alternatively, this
camera allows a synchronization of the flash firing at the end of
exposure (
End of Exposure End of Exposure
), right before the second shutter curtain
closes the image window. The sharp image will in this case be a
rendering of the end of the captured motion. This flash technique
creates a more natural impression of movement and dynamics in
the image.
This function is available with all camera and flash unit settings.

Notes
• Do not use synch cables that are longer than 3 m/10 feet.
• When using the flash with faster shutter speeds, a difference
between the two flash firing points will be barely discernible or
only noticeable for very fast movements.
