13.0 Open Platform – Freedom of Choice
Phase One’s Open Platform policy delivers maximum choice and compatibility
with a wide range of dierent 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/AF, Mamiya 645DF/AFDIII or 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 dierent to the image
sensor size of the three IQ models. Go to page 92 to nd out more about
the IQ sensors and go to page 155 for the full list of focusing Screens and
viewnder masks.
