selector setting. The amount of compensation
has to be determined by experiment.
Please refer to your flash unit’s operating in-
structions for more information about other
functions when using the D-Flash 40, automat-
ic flash light metering that conforms to System
SCA flash photography with flash sensors, or
with non-automatic flash units.
Viewfinder indicator - (503CW only) 52
Flash operation and flash battery-check are
indicated by a red light, located under the left
edge of the focusing screen. It is operative only
when a dedicated flash is connected to the TTL
socket. It indicates three separate states as de-
scribed below.
Ready signal
A steady red light indicates that the flash unit
is charged and ready to be fired. Absence of any
signal indicates the need for fresh batteries.
Confirmation signal
A flashing red light occurring for just over a
second immediately after exposure confirms
that the light output was sufficient for a proper
exposure. It then remains dark until the flash
unit has recharged. The steady red light will
then reappear indicating operative status again.
The time of reappearance however may vary ac-
cording to the condition of the batteries.
No result signal
Absence of the flashing confirmation signal
after exposure indicates that the flash emitted
was not sufficient for correct exposure. The ap-
erture must then be opened more or the flash
distance to the subject reduced. Changing to a
faster film is also a possibility.
The Rear cover MultiControl (51070) − sup-
plied − has a flash exposure control facility in
the form of a grey panel on the inside. It simply
replaces the magazine temporarily to provide
an inexhaustible standard reference for flash
exposure testing at no cost in terms of film. It
is particularly useful when exposing films with
a narrow exposure latitude, such as transpar-
ency film.
The camera’s flash control system reads light
reflected directly off the film plane, and is gov-
erned by the reflective characteristics of the
film emulsion that the grey panel simulates.
When using a dedicated flash unit proceed as
follows:
1. Set up the flash unit with the camera normal-
ly, using the TTL/OTF function setting.
2. Replace the magazine with the Rear cover
MultiControl .
3. Make a test exposure.
4. Note the exposure indications in the view-
finder. If warned by the camera for under-
exposure then make the appropriate changes
by altering the aperture or flash-to-subject
distance. Make further tests until the camera
indicates correct exposure.
5. Replace the Rear cover MultiControl with a
magazine and proceed as normal, using the
adjusted exposure settings.
