This sale is for a mint Mamiya RB67 / RZ67 Eye Correction Lens +2.0 Dioptre for the later Mamiya RB67 and RZ prism finders, including the RB67/RZ67 non-meter prism type L2, RB67 and RZ67 PD prisms, and the RZ67 Pro and Pro II AE prisms. It will not fit the original model RB67 prisms. This is an eyesight correction lens for those with long sight.
This dioptre simply clips into the prism finder eyepiece. This dioptre is in mint condition with absolutely minimal signs of use – it is almost certainly unused. The original box is included but it is not in perfect condition. Mamiya part numbers 514582 and 4957672202323.
