PhaseOne 645DF+ - Page 44

Phase One 645DF+ features TTL (Through The Lens), OTF (Off The
Film) and electronic ash exposure metering. A ash sensor located
inside the camera body reads the ash light reected off 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.
