Paris, brass bound lens engraved with exposure and distance tables, in the original leather case. A rare and early example of this type of lens which at the time were advertised as telephoto lenses but are more accurately described as vari-focal lenses which have to be re-focused each time the focal length is changed. Ex Spira Collection.
