This vintage shoe mount multiple focal length Zeiss Ikon 440 viewfinder can be used with 25mm, 35mm, 50mm, 85mm, and 135mm lenses. It was intended for use on Contax II cameras. It has light discoloration on its topside and a couple of scuffs and scratches on its exterior. There is a very light haze inside of it, but its glass is free of any fungus or separation.
