This is a Mamiya Eye Piece Magnifier for Mamiya RB/RZ67 Prism Finders. Will work on all current finders such as Prism Finder 2, AE, and AE II Prisms. Will not work with the older Prisms for the RB.
This magnifier will go over your eyepiece and allow you to magnify the center for critical focusing and then pop back up out of the way for full viewing. Even has a built-in diopter adjustment. This eyepiece is in Excellent Condition and shows normal wear. If you want critical focusing, this is what you need.
