14.0 Open Platform – Freedom of Choice
Phase One’s Open Platform policy delivers maximum choice and
compatibility with a wide range of different camera platforms.
This section covers the IQ back’s compatibility with the Hasselblad V
and H series, Mamiya RZ67, Phase One 645, Mamiya 645, Contax 645
and View Camera solutions.
Double Exposure Protection
It is not possible to accidentally double expose an image by capturing
one shot quickly after another when an IQ back is used on cameras
such as the Phase One 645DF/DF+ and Hasselblad 555 ELD (DIG
mode). The electronic communication with the body ensures that the
IQ back is ready before allowing release of the next shot. However,
users of other camera bodies that do not use the electronic interface
from the IQ will have to wait for the ready beep signal before releasing
the next shot.
Viewnder Masks
Cameras including the Mamiya RZ67 and Hasselblad V-series need a
viewnder mask as the image area of these models is different to the
image sensor size of the three IQ models. Go to page 99 to nd out
more about the IQ sensors and go to page 168 for the full list of
focusing Screens and viewnder masks.
