14.2 Viewnder Masking
The image area of Mamiya RZ67 at 56x69.5 mm is larger than the size of the four
IQ1 model’s sensors so it is necessary to insert a viewnder mask.
There are two dierent masks available for the Mamiya RZ67 according to
which IQ1 is being used. (The size IQ180 and IQ160 models CCD is 53.9x40.4
mm while the IQ150's CMOS and IQ140’s CCD measures 44x33mm and
43.9x32.9mm, respectively). Please check page 159 for the relevant
viewnder mask.
