This sale is for a very rare and really excellent condition RZ67 Pro 6x6cm viewfinder mask. It is suitable for use with the RZ67 120/220 6×6 back on any RZ67 camera – Pro, Pro II or Pro IID.
This is really hard to find mask is slightly distorted but sits flat in the viewfinder; otherwise only very minor signs of use.
Try finding another one – really really hard to find.
