This sale is for a mint condition Mamiya RB67/RZ67 Prism Magnifier FD701 – suitable for any RB67 or RZ67 standard, PD or AE prisms.
There are absolutely minimal signs of use, as can be seen in the photos. Everything works perfectly.
This is an extremely rare item – these come up very seldom on eBay. I use one regularly – really a most useful accessory. Essential for achieving accurate focus when using a prism. Please note that this magnifier cannot be used with the original RB67 Pro/ProS angled prism finders, but it is suitable for all later models.
