The Juwel-Klapp-Camera is an example for Emil Wünsches standard amateur folding cameras. It was a folding bed camera for 9x12cm film plates. It has a Newton type viewfinder and a kind of pneumatically triggerable moment shutter. It was offered with lenses from renowned makers: Voigtländer's Collinear, Steinheil's Orthostigmat or Goerz's double anastigmat. The cheapest variant had just one of Wünsche's periscopic Rapid-Aplanats, the medium quality variant a Wünsche Mars-Anastigmat.
