Using a dedicated SCA-3562 adapter
In conjunction with dedicated flash units and an
SCA-3562 (or SCA-356) adapter, the TTL flash-
metering feature of the camera can be used.
Switch your flash unit off, attach the adapter,
connect it to the camera and set it to TTL.
During exposure, the sensor incorporated in the
camera will meter the light reflected from the
film or sensor surface and control flash duration
according to film speed and ambient light level.
The result is optimum exposure accuracy within
a range of ISO 25 to ISO 1600.
Camera and flash unit interchange the follow-
ing data via the flash adapter:
»
Focal length of AF lenses to control the flash
reflector
(Note: For technical reasons, focal lengths are
converted to 35mm equivalents).
»
Lens-aperture and film-speed settings to con-
trol the autoflash unit.
»
Reading of flash compensation in suitable
flash units.
»
Control of AF preflash
FLASH PHOTOGRAPHY
Manual flash without SCA adapter
Switch your flash unit off and connect it to the
camera´s hot shoe or PC terminal. In this case,
the camera will not detect your flash unit and
behave as if no flash were connected. On AF
lenses or the camera (with AFD lenses), set the
aperture as required by your flash unit.
Autoflash units control the light output required
for an aperture set on flash and camera via their
integral sensor. With simpler flash units, the
flash aperture will have to be determined as a
function of subject distance (table on flash).
For details, please see the instructions of your
flash unit.
