Mamiya RZ67 AE Prism Viewfinder (Model 2) projector it works great tooThe Mamiya AE Prism Viewfinder (Model 2) fits the RZ67 medium format camera and provides a slightly angled eye level view of your focusing screen plus metering and autoexposure control. Yes, it's kind of awkward to hold an RB RZ at eye level, but sometimes it's nice to have the option. In good cosmetic condition, with some finish wear; there is some dust and spots of mildew in the optics. Function is good, though!
