This sale is for a used but still really good condition Mamiya RB67/RZ67 Prism Magnifier FD701 – suitable for any RB67 or RZ67 standard, PD or AE prisms.
There is slight paint loss on sharp edges, as can be seen in the photos. Apart from this, the dioptre locking screw is missing but it all works perfectly and is not really a problem. It has minimal effect on using the magnifier.
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.
