6.1 General description
In this mode the slave flash unit is triggered by the
light emitted from the camera’s built-in flash unit.
Olympus digital cameras emit, when in flash
mode, one or two preflashes a fraction of a se-
cond before the picture is shot or the main flash is
fired. These preflashes do not contribute to the ex-
posure of the picture. The SCA 3202 adapter con-
trols the slave such that it is triggered at the same
time as the main flash.
The flash unit can be operated both in the auto
flash mode A or in the manual flash mode M.
For system reasons cordless slave operation
in TTL mode is not possible. If the flash unit is
set in the flash mode TTL or EM (EM = Easy-
Mode-TTL; only with 40 MZ-..., 50 MZ-5),
then the display
of the SCA adapter will
start to flash as a warning! We recommend to
use the auto flash mode A of the flash unit!
Ensure that the light sensor at the front of the SCA
adapter can receive the camera’s flash light re-
flected off the subject in order to be able to trigger
the slave unit. Do not cover the light sensor in the
SCA adapter!
The maximum distance to the subject depends on
the ambient light and the light-reflecting proper-
ties of the subject or the ambient area of the sub-
ject. Consequently, concrete distance values for
the maximum working range of the slave flash
unit cannot be given. The subject should not be
further away from the camera or the slave flash
unit so that the light sensor inside the SCA adap-
ter can still receive sufficient reflected light from
the camera’s flash unit to reliably trigger the slave.
