Chronology of cameras Kodak 

From the early 1960s to the mid-1980s, Kodak manufactured thousands of cameras in the 126 and 110 formats under the generic name "Instamatic" (trademark registered in 1962). Dozens of versions, including those not bearing this name, were released year after year.
Kodak's idea was not only to sell these cameras but primarily to sell the films that could be used with them. Many other brands followed Kodak's lead and manufactured cameras and films, paying royalties to Kodak.
To achieve its goal, Kodak introduced film cartridges that were very easy to load and cameras that were extremely user-friendly.

Kodak
The patent 3,138,081 was published on June 23, 1964. It was filed by Kodak, and its inventor was Hubert Nerwin.
This patent pertains to a 35mm film contained in a closed cassette. The cassette is asymmetrical and serves both as a supply spool and a take-up spool. There is no possibility of inserting it incorrectly into the camera due to its design. The film is perforated on one side only. The back of the film is backed by paper bearing a frame number, following the principle of inactinically readable numbers on the back of cameras, eliminating the need for a mechanical frame counter. The camera only requires one drive shaft since there is no need to rewind the film. The cassette is returned to the Kodak laboratory after the last exposure without further handling.

With this innovative system, photographers no longer risk mispositioning the film's starting tab or tearing the perforations. Also known as Kodapak, the 126 format was available in 20 and later 24 exposures (with a brief period of 12 exposures) in both color negative and slide film.

Film and 110 camera

Kodak 110On June 1, 1971, patent 3,581,641 for a cartridge camera was published. It was filed by Kodak, with Hubert Nerwin as the inventor. This patent incorporates the principles outlined in patent 3,138,081, referencing it, but the cartridge is smaller in size.

Brevt codage kodakIn 1966, Kodak (with Hubert Nerwin as the inventor) filed a patent (3,444,795) to equip film cartridges (which resembled but were not limited to 126, 110, film, 135 formats) with a coding system that allowed cameras or other devices to recognize the cartridge and its contents. The system was based on notches or notches in the cartridges.

Kodak camera using the 126 film

The evolution of Instamatic 126 cameras primarily followed advancements in flash technology. The early models had a deflector for an AG1 bulb, and then the cameras were modified to accommodate a battery because flashcubes required an electrical pulse. Finally, the Magicube, which still contained four bulbs but no longer required a battery, led to another modification of the cameras. Cameras using the Magicube have an "X" in their name. This "X" is sometimes separated from the number by a hyphen, and other times it's not. Inconsistencies in naming can even be found between the camera itself and its packaging. Cameras using the Flipflash have an "F" at the end of their name.

Appareils Kodak utilisant le film 110

Lancés plus tardivement que les Instamatic 126, les 110 ne connurent pas les Flashcube.

Les premiers modèles sont destinés to être utilisés avec un Magicube. Ils s'appellent Instamatic, and pour éviter la confusion avec les 126, on précise que ce sont des Pocket Instamatic. Etrangement quelques modèles bien que manifestement membres de la même famille ne portent pas le "Pocket".
Les modèles avec Magicube cèdent la place aux modèles utilisables avec un Flipflash. Les premiers avec Flipflash continuent to utiliser le mot Instamatic, mais leur aspect and leur nom changent ; le capot de protection sert aussi de poignée and le nom devient Ektra.
Les modèles to flash électronique intégré qui apparaissent to la fin des années 70 intègre le mot Lite dans leur nom ; Lite pour Light (lumière). A chacun de ces grands changements, il semble y avoir eu chez Kodak une période de flou où les régles de nommage ne sont pas bien suivies.

Certains modèles échappement complètement to ces régles, ce sont généralement des modèles se démarquant franchement du reste de la production ou réservés to certains marchés.

__________

The Ektra 250 was manufactured in Germany from 1980 (announced in France in 11/80) to 1983. Its lens is a Kodar 25mm f/9.5, without focusing, from 1.20m to infinity. It is equipped with a slider that allows you to select one of three symbols (also visible in the viewfinder): sun, clouds or flash. With 400 asa sensitivity film, the sun corresponds to a speed of 1/250 sec, this speed dropping to 1/25 with 64 or 100 asa film. The cloud position corresponds to a speed of 1/50 whatever the film. When a flash is used, the speed is 1/50 sec.
Its viewfinder is collimated (bright lines).

FlipflashFlipFlashFlipflash

The Flipflash is a vertical bar with 8 flashbulbs. At each end, there is a notch to attach it to the camera. The eight bulbs are divided into two sets, each corresponding to one of the notches. After the first four bulbs are used, the bar needs to be rotated 180°.

The Flipflash has the advantage of distancing the flashbulb from the lens axis, which reduces the red-eye effect.

The patent 3,937,946 published on February 10, 1976, filed by General Electric (with inventor Kurt H. Weber), presents the Flipflash. It builds upon several earlier patents for multi-lamp flashes, but those were arranged horizontally.
