The Voigtländer Heliar Aspherical 40mm f2.8 is a lovely little classic-style lens for the Leica thread mount. It provides a slightly wider-than-normal field of view than a typical 50mm lens, but not so wide that you can't use it for everyday shooting. In a lovely glossy black paint finish, with clean glass, only very minor wear. Includes front and rear caps and original box.
