Phase One 645DF features TTL (Through The Lens), OTF (O The Film) and
electronic ash exposure metering. A ash sensor located inside the camera
body reads the ash light reected o the surface of the CCD at the moment
of exposure. The sensor is connected via the Phase One 645DF’s dedicated
hot-shoe to a shoe or handle-mount style Metz ash unit via the Metz SCA
3952 TTL Adapter. Maximum ash speed is 1/125 sec. when the focal plane
shutter is used, making daytime synchronization possible.
The ISO of the ash is automatically set through the TTL connection from the
camera’s lm magazine; any adjustment to this is instantly recognized after
the setting is locked and the shutter release is half-pressed.
To utilize the TTL ash feature with all TTL-operable Metz ash units, a Metz
SCA 3952 module is required. Please see the chart for capability and/or
additional adapters that may be necessary.
The resulting ash exposure automation determines correct ash exposure
and automatically adjusts the output of the ash. It also automatically
corrects for exposure compensation normally required when using lters,
close-up bellows or extension tubes.
1. Mount the SCA3952 adapter onto the Metz ash, 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.
