I have never seen much about this viewfinder and I recently found one of these used. These are *large* viewfinders and the magnification is larger than the Fuji VF-X21, Voigtlander 21/25 or Ricoh GV-1. Its larger size also means it isn't blocked as much by a lens or hood. It also has considerably more eye relief and 'sees' further beyond the framelines, to the point that I can read the focus scale on an adapted Super-Angulon-R 21mm lens when mounted on a M240.

That's some seriously large field of view.
