Disc film was a cartridge-based film format for still photography, introduced by Kodak in 1982.
The film was in the form of a disc with 15 exposures arranged around the edge, contained in a slim cartridge. Each negative was just 8mm x 10.5mm, less than 40% of the size of the already small 110 film negatives.
Disc cameras were aimed at consumers and were generally completely automated and very simple to load and unload.
The size of the negative led to generally unacceptable grain and poor definition in the final prints. The film was intended to be printed with special 6-element lenses from Kodak, but many labs simply printed discs with standard 3-element lenses used for larger negative formats.
The film was officially discontinued by the last manufacturer, Kodak, in 1997, though Disc cameras had disappeared from the market long before then, with Kodak ending production in 1988. In its lifetime though, over 25 million Disc cameras were sold.
