Mamiya 645DF+ features Through the Lens (TTL), Off the Film/Sensor
(OTF) and electronic flash exposure metering. A flash sensor located
inside the camera body reads the flash light reflected off the surface of
the CCD at the moment of exposure. The sensor is connected via the
Mamiya 645DF+’s dedicated hot shoe to a shoe or handle-mount style
Metz flash unit via the Metz SCA 3952 TTL Adapter. Maximum flash
speed is 1/125 second when the focal plane shutter is used, making
daytime synchronization possible.
The ISO of the flash is automatically set through the TTL connection from
the digital back; any adjustment to this is instantly recognized after the
setting is locked and the shutter release is half-pressed.
To utilize the TTL flash feature with all TTL-operable Metz flash units, a
Metz SCA 3952 module is required. See the chart for capability and/or
additional adapters that may be necessary.
The resulting flash exposure automation determines correct flash
exposure and automatically adjusts the output of the flash. It also
automatically corrects for exposure compensation normally required
when using filters, close-up bellows or extension tubes.
1. Mount the SCA 3952 adapter onto the Metz flash, insert fully into the
camera’s hot shoe, and then tighten with the locking knob
A
.
2. Set the exposure mode, and then check the shutter speed and
aperture.
