This sale is for one Mamiya RB/RZ67 WLF -1.5 Dioptre for the standard RB ProS/ProSD and RZ waist level finders. It will not fit the original RB67 Pro finder – the one without the sliding locking bar.
This dioptre simply clips into the WLF. This dioptre is very clean with minimal signs of use. This is the standard dioptre supplied with all WLF when new – it acts as a magnifier rather than correcting fault eyesight..
