Voigtländer Vito
The Vito and Vitomatic, Vitoret, and Vito Automatic were several related lines of 135 film, 35 mm compact viewfinder and rangefinder cameras made by Voigtländer from the 1940s through the early 1970s, equipped with leaf shutters, similar in concept to and marketed against the competing Kodak Retina cameras manufactured by Kodak. All of these cameras were fixed-lens models; the models in the ''Vito'' line identified with Roman numerals were Folding camera, equipped with folding mechanisms and collapsible lenses for portability, while the others were rigid, non-folding cameras. Within the Voigtländer lineup of 35 mm film cameras, the ''Vito'' were a simplified camera line aimed at amateur photographers; the high-end Voigtländer Prominent, ''Prominent'' (135) were rangefinders meant for professionals, and the mid-range Voigtländer Vitessa, ''Vitessa'' were available with an expanded selection of mostly fixed lenses for advanced amateurs. Voigtländer also offered a line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeiss Tessar
The Tessar is a photographic lens design conceived by the German physicist Paul Rudolph in 1902 while he worked at the Zeiss optical company and patented by Zeiss in Germany; the lens type is usually known as the Zeiss Tessar. A Tessar comprises four elements in three groups, one positive crown glass element at the front, one negative flint glass element at the center and a negative plano-concave flint glass element cemented with a positive convex crown glass element at the rear. History Beginnings Despite common belief, the Tessar was not developed from the 1893 Cooke triplet design by replacing the rear element with a cemented achromatic doublet. Paul Rudolph designed the Anastigmat with two lenses cemented in 1890. Later, Rudolph thought that a narrow airgap in the form of a positive lens would correct the spherical aberration (as did HL Aldis in 1895) and that this device was much better than the lenses cemented. In addition, this allowed the photographers to have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
