The Phase One P back can be used on most large for-
mat cameras via the optional Phase One FlexAdaptor
and the enclosed lens sync cable (value added pack-
age only). The P back supports most mechanical
shutters and the Horseman ISS electronic shutter. To
ensure optimal image quality, Phase One strongly rec-
ommends shutters that can be fired twice within four
seconds. The first release of the shutter activates the
CCD, the second release takes the picture. If the time
limit of four seconds is exceeded, the camera gives
a warning “beep” followed by a “ready” signal. If for
some reason it is not possible to fire the shutter twice
within the time limit, the camera will send a time-out
error message to the screen.
