The Voigtländer objectives were revolutionary because they were the first mathematically calculated precision objectives in the history of photography, developed by the German-Hungarian mathematics professor Josef Maximilian Petzval, with technical advice provided by Peter Voigtländer. Voigtländer went on to produce the first Petzval portrait photographic lens (the fastest lens at that time: f/3.6) in 1840, and the world's first all-metal daguerreotype camera (Ganzmetallkamera) in 1840, also bringing out photographic plate cameras shortly afterwards.


A camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or both. The images may be individual still photographs or sequences of images constituting videos or movies.
