This sale is for a Bronica ETRS Eye Correction Lens -0.5 D for the standard prism E / AE-II Prism E, complete with original box and storage case. Please see my other listings; I have other dioptres available.
This dioptre simply replaces the standard -1.5 dioptre supplied with every Bronica ETR prism, Just unscrew your existing dioptre and fit this in its place. This dioptre is very clean with minimal signs of use.
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.
