August Nagel (June 1882 - October 1943) was a German camera manufacturer and designer. He was among the founders of Zeiss-Ikon and later left to form Nagel Werke, which he subsequently sold to Eastman Kodak. His most notable legacy is the Kodak 135 film cartridge which remains the world standard for 35mm still-cameras.
In 1908, at 26, he and his friend Carl Drexler founded Drexler & Nagel in Stuttgart, to produce photographic equipment. In 1908 they produced the Contessa No. 1 in the 4 ½ x 7 cm format. In 1909, the company was renamed Contessa Camera Works Stuttgart. The ever-growing plant developed 23 different models by 1910, to be exported around the world. As a passionate sportsman and balloon enthusiast, Nagel pioneered the development of cameras for cartographic, geographical and military areas. He developed a special balloon camera. In recognition of the work on the balloon and aviator cameras, in 1918, the University of Freiburg awarded the 36 year old inventor the honorary title of Doctor.
During the First World War, the factory with 500 employees, produced military equipment. After the war the company grew through innovation and acquisition and became known as Contessa-Nettel. In 1926 Nagel merged Contessa-Nettel with three other firms: Ernemann, Goerz and Ica, and with financial backing from Zeiss, formed Zeiss Ikon. August Nagel was director of manufacturing. However, only two years later he left to form Dr.-August Nagel-Factory, and produced the Librette, Recomar, Vollenda, and Pupille cameras among others.
In 1932 he sold his company to Eastman Kodak, forming the Kodak AG division. With additional funding Nagel began to develop a high quality yet affordable 35mm camera to compete with Leica and Contax. With the release of the Retina 35mm camera, he also introduced a new pre-packaged 35mm cartridge known as Kodak 135 film. This was the first pre-rolled 35mm film cartridge and it would fit into both the Leica and the Contax cameras. This became the 35mm film standard that is still used today.
The Retinas and the economy Retinette cameras became the main 35mm Kodak offering in Europe and America. As WWII approached these were the most important Kodak AG products. August Nagel died in 1943 at the age of 61 years, but production continued through and after the war. Retina cameras continued to evolve and diversify through the late 1950s when Japanese competition crushed the German camera industry. Though in decline, Kodak AG offered single lens reflex cameras with interchangeable lenses into the 1960s. Later products declined in quality and features, with the last of the Retinas being simple viewfinder cameras with modest fixed lenses. Though not branded as a Retina, the Kodak Instamatic Reflex of 1968 - 1972 was essentially a Retina Reflex with interchangeable lenses, but using the Instamatic film cassettes.

A rangefinder camera is a camera fitted with a rangefinder, typically a split-image rangefinder: a range-finding focusing mechanism allowing the photographer to measure the subject distance and take photographs that are in sharp focus.
135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film with a film gauge of 35 mm (1.4 in) loaded into a standardized type of magazine for use in 135 film cameras.
126 film is a cartridge-based film format used in still photography. It was introduced by Kodak in 1963, and is associated mainly with low-end point-and-shoot cameras, particularly Kodak's own Instamatic series of cameras.
The Instamatic is a series of inexpensive, easy-to-load 126 and 110 cameras made by Kodak beginning in 1963. The Instamatic was immensely successful, introducing a generation to low-cost photography and spawning numerous imitators.
Carl Zeiss AG, branded as ZEISS, is a German manufacturer of optical systems and optoelectronics, founded in Jena, Germany in 1846 by optician Carl Zeiss. Together with Ernst Abbe and Otto Schott he laid the foundation for today's multinational company. The current company emerged from a reunification of Carl Zeiss companies in East and West Germany with a consolidation phase in the 1990s. ZEISS is active in four business segments with approximately equal revenue in almost 50 countries, has 30 production sites and around 25 development sites worldwide.
The Tessar is a photographic lens design conceived by the German physicist Dr. 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 ZeissTessar. Since its introduction, millions of Tessar and Tessar-derived lenses have been manufactured by Zeiss and other manufacturers, and are still produced as excellent intermediate aperture lenses.
Praktica was a brand of camera manufactured by Pentacon in Dresden in eastern Germany, within the GDR between 1949 and the German reunification in 1990. The firm Pentacon was divided in mainly two parts and sold after German reunification. Schneider Kreuznach and Noble bought parts of it. Pentacon is a Dresden-based company in the optical and precision engineering industry, which was at times a major manufacturer of photo cameras. The name Pentacon is derived on the one hand from the Contax brand of the Dresden Zeiss Ikon Kamerawerke and Pentagon, because a pentaprism for SLR cameras developed for the first time in Dresden has this shape in cross section. Today's PENTACON GmbH Foto- und Feinwerktechnik is still based in Dresden. It is part of the Schneider Group, Bad Kreuznach. Pentacon is the modern-day successor to Dresden camera firms such as Zeiss Ikon; for many years Dresden was the world's largest producer of cameras. Previous brands of the predecessor firms included Praktica, Exa, Pentacon, Zeiss Ikon, Contax, Ica, Ernemann, Exakta, Praktiflex, and many more.
Contax began as a German camera model in the Zeiss Ikon line in 1932, and later became a brand name. The early cameras were among the finest in the world, typically featuring high quality Zeiss interchangeable lenses. The final products under the Contax name were a line of 35 mm, medium format, and digital cameras engineered and manufactured by Japanese multinational Kyocera, and featuring modern Zeiss optics. In 2005, Kyocera announced that it would no longer produce Contax cameras. The rights to the brand are currently part of Carl Zeiss AG, but no Contax cameras are currently in production, and the brand is considered dormant.
Retina was the brand-name of a long-running series of German-built Kodak 35mm cameras, produced from 1934 until 1969. Kodak Retina cameras were manufactured in Stuttgart-Wangen by the Kodak AG Dr. Nagel Werk which Kodak had acquired in December 1931.
The Zeiss Sonnar is a photographic lens originally designed by Dr. Ludwig Bertele in 1929 and patented by Zeiss Ikon. It was notable for its relatively light weight, simple design and fast aperture.
The Contaflex series is a family of 35mm Single-lens reflex cameras (SLR) equipped with a leaf shutter, produced by Zeiss Ikon in the 1950s and 1960s. The name was first used by Zeiss Ikon in 1935 for a 35mm Twin-lens reflex camera, the Contaflex TLR; for the earlier TLR, the -flex suffix referred to the integral reflex mirror for the viewfinder. The first SLR models, the Contaflex I and II have fixed lenses, while the later models have interchangeable lenses; eventually the Contaflexes became a camera system with a wide variety of accessories.
The Contax I, or Original Contax, is a 35 mm rangefinder camera made between 1932 and 1936 by Zeiss Ikon. The Contax I had six identifiable variants, but fundamentally identical; every aspect was designed to outperform the Leica. For instance, the removable back was for faster loading and reloading, the bayonet lens mount was designed for rapid lens interchangeability, the long-base rangefinder allowed more accurate focusing, and the vertical metal shutter not only gave a faster maximum speed but also banished the problem of shutter blinds burning.
The Kodak Retina Reflex is a discontinued series of four single-lens reflex cameras made by Kodak in Germany between 1957 and 1974, as part of the Kodak Retina line of 35mm film cameras.
The Contax II is a 35 mm rangefinder camera. It was released in 1936 and was the successor of the original Contax later called the Contax I. It was the first camera with a rangefinder and viewfinder combined in a single window. Its chief designer was Hubert Nerwin. The Nettax was meant to be a cheaper alternative, it was a derivative of the Super Nettel with a rigid body and interchangeable lenses with a specific bayonet and a very limited range of lenses.
During the 1930s, Zeiss Ikon (ZI) made a wide range of miniature cameras for the 35mm film format. Most cameras used the standard 24×36 mm frame size, like the Contax, Nettax and Super Nettel. However, the ability to take images in fast sequence was a popular marketing element at the time, and several fast-operating models were made. Among these were the Otto Berning's motor-driven Robot cameras as well as the ZI lever-operated Tenax I and Tenax II. These have the smaller square format of 24×24 mm, enhancing faster frame advance.
Contarex is a line of 35mm single lens reflex cameras (SLRs) made by Zeiss Ikon. It was first presented at Photokina in 1958 and initially scheduled for delivery in the spring of 1959, but it was not made generally available in the United States until March 1960. The first model is popularly known as the Contarex I, the Bullseye, or the Cyclops, after the prominent light meter window above the lens, in front of the pentaprism. The camera was aimed at the high-end and professional markets; in 1961, the retail price was $499.
Ludwig Jakob Bertele was a German optics constructor. His developments received universal recognition and serve as a basis for considerable part of the optical designs used today.
The Zeiss Hologon is an ultra wide-angle f=15mm f/8 triplet lens, providing a 110° angle of view for 35mm format cameras. The Hologon was originally fitted to a dedicated camera, the Zeiss Ikon Contarex Hologon in the late 1960s; as sales of that camera were poor and the Zeiss Ikon company itself was going bankrupt, an additional 225 lenses were made in Leica M mount and released for sale in 1972 as the only Zeiss-branded lenses for Leica rangefinders until the ZM line was released in 2005. The Hologon name was revived in 1994 for a recomputed f=16mm f/8 lens fitted to the Contax G series of rangefinder cameras.
Icarex is a line of 35mm single lens reflex cameras (SLRs) made by Zeiss Ikon, derived from an earlier Bessaflex project developed by Voigtländer. The Icarex line, which included the Icarex 35, Icarex 35CS, Icarex 35S, and SL 706, was aimed at a mid-range market above the Contaflex SLR, which was intended for advanced amateurs, but below the Contarex line for professionals.
The Vitessa was a line of 35mm compact rangefinder cameras made by Voigtländer in the 1950s, equipped with leaf shutters, similar in concept to and marketed against the competing Kodak Retina cameras manufactured by Kodak. Most of the Vitessa cameras were fixed-lens models equipped with collapsable lenses for portability. One of the later Vitessa models, the Vitessa T (1956), introduced the Deckel (DKL) bayonet mount for interchangeable photographic lenses.
