This sale is for a near mint condition Mamiya M645 Right Angle Finder for the M645, M645J and M645 10000S cameras only – it will not fit other Mamiya models.
This quite rare right angle finder is in near perfect condition with really minimal signs of use, very close to mint. It includes +4 to -4 dioptre adjustment so you can avoid the use of glasses. Fits any M645 prism (standard, CdS, PD or AE) – but not the later Super / Pro / Pro TL models. Very easy to fit and perfect for normal and macro work while using a metered prism.
Try finding another one – these are really hard to find.
