Hasselblad 503CX Instruction Manual

Automatic Flash Control
The camera's built-in flash sensor and electron-
ics measure the light reflected from the central
portion of the film surface, a circle with a diameter
of 40mm. The metering system is connected to a
selector for setting film speed, and with
an SCA
390 or 590 adapter
it provides a control signal
which
is transmitted to a flash unit conforming to
the corresponding System SCA 300 or 500. The
S03cx only
signal regulates the flash unit, cutting off the flash
when the exposure is correct. Under the left edge
of the focusing screen an indicator light shows
when the flash is ready to be operated and then
confirms if the amount of light emitted was suffi-
cient to provide a correct exposure. The flash unit
powers both the camera's electronics and the
adapter.
