Settings for camera-controlled automatic flash mode
When the flash unit used has been switched on and set to the
appropriate mode for TTL flash exposure control (see flash man-
ual), exposure metering must be carried out on the camera:
1. before taking each flash picture by gently pressing the shutter
release, so that the display in the viewfinder shows the shutter
speed or switches to the light balance. If this stage is missed
out by fully depressing the shutter release in one quick move-
ment, the flash unit will not fire even if required.
2. The shutter speed dial must be set to
A, to the flash sync
speed (
1
⁄180s), or to a slower shutter speed (including B). In
aperture priority mode, the camera determines the shutter
speed in line with the ambient light, but limits slow shutter
speeds in line with the 1/focal length rule to reduce blurring.
3. The desired aperture, or the aperture required for the relevant
distance to the subject, must be set.
Note:
If the utomatically controlled or manually set shutter speed is faster
than
1
⁄180s, the flash is not fired unless the flash unit is HSS-compat-
ible (see p. 89).
Flash exposure displays in the viewfinder with system-com-
patible flash units
A flash-shaped LED appears in the viewfinder as confirmation and to
display the various operating conditions. This LED appears together
with the displays for exposure metering for the ambient light level,
described in the relevant sections.
In automatic flash mode
(flash unit set to GNC or TTL)
•
does not appear despite the flash unit being switched on and
ready for use:
A faster shutter speed than
1
/
180
s is set manually on the camera
and the connected flash unit is not HSS-compatible. In such
cases the camera will not fire the flash unit even though it is
switched on and ready for use.
•
flashes slowly (at 2Hz) before the picture is taken:
The flash unit is not yet ready to use
•
is lit up before the picture is taken:
The flash unit is ready for use
•
remains continuously lit after taking the picture, and the other
displays go out:
The flash is still ready to use.
•
flashes rapidly after taking the picture (at 4Hz), and the other
displays go out:
It is not yet ready to use again.
•
goes out after taking the picture, together with the other
displays:
Underexposure, perhaps due to the choice of too small an
aperture stop for the subject.
