This sale is for a Bronica ETRS / ETRSi Eye Correction Lens +0.5 D for the Waist Level Finder E, complete with original storage case and box. Please see my other listings; I have many other dioptres available (most not listed) and if you cannot see what you want please just ask.
This dioptre simply replaces the standard -1.5 dioptre supplied with every Bronica ETR WLF, Just unscrew your existing dioptre and fit this in its place. This dioptre is very clean with really minimal signs of use; I doubt whether it has been used.
A large (but definitely nowhere near complete) selection of Mamiya, Bronica and Fuji GX680 dioptres available and I do not have time to list them all; if you cannot see the one you want then just ask.
Note that this dioptre is not suitable for any Bronica finders except the ETR series waist level finders.
