Way before the Voigtlander, Cosina actually made a Cosina Body same like the Bessa L and also a 15mm lens too, but the brand indicated on the Body and lens is Cosina
The design, shape and weight are the same as the Voigtlander ones.
But I need to find out the Voigtlander an improved lens over the old Cosina ones
