ATTACHING THE FLASH UNIT
Before attaching a flash unit to the flash shoe (20) on the camera,
the cover that protects the flash shoe and the socket (28) when
not in use, must be detached to the rear, and
the camera and flash unit must be turned off.
When attaching a flash unit, you should ensure that the foot of the
flash unit is fully inserted into the flash shoe and the clamping nut
is tightened to prevent it accidentally falling out. This is particularly
important for flash units with additional control and signal
contacts, because if the position in the flash shoe changes the
necessary contacts can be broken, leading to malfunctions.
Notes:
This also applies when using a flash unit with SCA adapter set
(see p. 228).
Make sure the flash shoe cover is always fitted when no
accessories are in use (such as a flash unit, an external
viewfinder or microphone). It will protect the socket 28 for a
time against water incursion.
FLASH MODE
Fully automatic flash mode, i.e. controlled by the camera, is
available on the camera with the system-compatible flash units
listed in the previous section, and in aperture priority
A and manual
exposure modes.
In addition, automatic illumination control is operational in all three
exposure modes. This means that in order to ensure a balanced
relationship between flash and other lighting at all times, the flash
power is reduced by up to 1
2
/
3
EV as ambient brightness increases.
However, if the ambient brightness plus even the shortest possible
flash sync time of
1
/
180
s would cause overexposure, a non-HSS
compatible flash unit will not be fired in aperture priority mode. In
such cases the shutter speed is governed by the ambient
brightness and is shown in the viewfinder.
In aperture priority mode
A and with manual setting, the camera
also allows the use of creative flash techniques such as
synchronization of flash firing with the 2nd shutter curtain rather
than the 1st, as is usual, and flash with slower shutter speeds than
the sync speed of
1
/
180
s. These functions are set on the camera
using the menu (for more details, refer to the relevant sections
below).
In addition, the camera transfers the set sensitivity to the flash
unit. This allows the flash unit, provided it has received such
information and the aperture manually set on the lens is also input
to the flash unit, automatically to adjust its range values
accordingly. With system compatible flash units, the sensitivity
setting cannot be influenced from the flash unit as it is transferred
from the camera.
