The Leica 1.25x viewfinder magnifier is a tiny accessory that provides a touch of extra viewfinder magnification for your Leica M camera, ideal for precision focusing with longer lenses. This accessory screws into the viewfinder threads of any Leica M camera up the the M9 (the M10 and M11 require a thread adapter, which is not included.) Quite handy, though its only usable with lenses 50mm and up. In excellent condition, with leather case and tiny connecting lanyard, as pictured.
