In 1841 Peter Voigtlander designed and manufactured an all-metal daguerreotype camera with a new fast achromatic lens. It was the first use of metal for a camera in the world and it introduced a breakthrough lens which allowed for faster exposure times, thus enabling portrait photography. The lens was based on the 1840 calculations of Joseph M. Petzval, which consisted of two doublet lenses and an aperture stop located in between the two lens. This is a very rare and historic camera.
