In 1972, Kodak introduced the '''Pocket Instamatic''' series for its new 110 format.<ref name=PM-Berger-72>{{cite magazine |url=https://books.google.com/books?id=MdQDAAAAMBAJ&pg=PA74 |title=New from Kodak: World's smallest pocket camera for under $30! |author=Berger, Ivan |date=June 1972 |magazine=Popular Mechanics |pages=74–75 |volume=137 |number=6 |publisher=The Hearst Corporation |access-date=2 March 2023}}</ref> The 110 cartridge had the same easy-load cartridge design with an integral take-up spool as the 126 format, but was much smaller, allowing the cameras to be very compact (hence the "Pocket" designation). Many cameras carry a four-character date code inside the film compartment or on the door.<ref>{{cite web |url=https://kodak.3106.net/index.php?p=211 |title=Kodak 110 Instamatic Cameras |website=Kodak Classics |access-date=4 April 2023}}</ref>

At launch in the United States, there were five models: in ascending order of sophistication, the Pocket Instamatic 20, 30, 40, 50, and 60. The top-of-the-line model was the Pocket Instamatic 60, which featured a [[stainless steel]] body, rangefinder, and automatic exposure with a four-element 26&nbsp;mm {{f/|2.7|17}} ''Ektar'' lens. Programmed autoexposure selected an appropriate combination of aperture, with shutter speeds ranging from {{frac|250}} to 10&nbsp;seconds. The 50 shared the same lens and autoexposure system, but dropped the rangefinder for scale focusing. The 40 had a much slower 25&nbsp;mm {{f/|8}} three-element lens and two-position focusing, and the 30 had an even slower 25&nbsp;mm {{f/|9.5}} fixed-focus lens; both carried a similar programmed autoexposure system. The 20 shared the same 25&nbsp;mm {{f/|9.5}} fixed-focus lens as the 30 and offered a single shutter speed of {{frac|100}} second, which automatically changed to {{frac|40}} when a flashcube was inserted.<ref>{{cite web |url=https://www.pacificrimcamera.com/rl/02319/02319.pdf |title=Kodak Picture-Taking Equipment and Supplies Price Catalog |date=1972 |publisher=Eastman Kodak Corporation |website=Pacific Rim Camera, Reference Library |access-date=4 April 2023}}</ref> An entry-level Pocket Instamatic 10 was launched by 1973, with a fixed-focus 25&nbsp;mm {{f/|11}} lens and operation similar to the 20.<ref>{{cite web |url=https://www.pacificrimcamera.com/rl/02433/02433.pdf |title=Kodak Picture-Taking Equipment and Supplies Price Catalog |date=1973 |publisher=Eastman Kodak Corporation |website=Pacific Rim Camera, Reference Library |access-date=4 April 2023}}</ref>

By 1977, the initial lineup had been replaced by the ''Trimlite Instamatic'' and ''Tele-Instamatic'' lines for the United States. The Trimlite Instamatic 48 was a rebadged Pocket Instamatic 60, carrying the same features as the previous top-line model, and other Trimlites included the 38 (similar to the Pocket 40), 28 (Pocket 30), and 18 (Pocket 10). The Tele-Instamatics featured a sliding [[teleconverter]] switch. That line included the 708, which offered a new "multi-element" (three-element 25&nbsp;mm {{f/|5.6}} or four-element 43&nbsp;mm) lens with scale focusing and programmed autoexposure, similar to the prior Pocket 50, and the 608, which switched the single-element lens from 25&nbsp;mm to 43&nbsp;mm, both {{f/|11}}, with a fixed shutter speed similar to the prior Pocket 20; engaging the teleconverter also would switch the viewfinder.<ref>{{cite web |url=https://www.pacificrimcamera.com/rl/02433/02433.pdf |title=Kodak Picture-Taking Equipment and Supplies Price Catalog |date=June 24, 1977 |publisher=Eastman Kodak Corporation |website=Pacific Rim Camera, Reference Library |access-date=4 April 2023}}</ref>

Kodak introduced a mass-produced [[aspheric lens]] for still photography in October 1978 with the ''Ektramax'' 110 camera.<ref>{{cite journal |doi=10.1364/AO.24.001682 |author=Ruben, Paul L. |title=Design and use of mass-produced aspheres at Kodak |journal=Applied Optics |volume=24 |issue=11 |pages=1682–1688 |date=1985|pmid=18223774 |bibcode=1985ApOpt..24.1682R }}</ref> The lens is a four-element, 25&nbsp;mm {{f/|1.9}} design with scale focusing.<ref>{{cite magazine |url=https://books.google.com/books?id=i88DAAAAMBAJ&pg=PA32 |title=11 new snapshot cameras |author=Sahagian, Tom |date=January 1979 |magazine=Popular Mechanics |pages=30;32 |volume=151 |number=1 |publisher=The Hearst Corporation |access-date=4 April 2023}}</ref><ref>{{cite news |url=https://www.washingtonpost.com/archive/lifestyle/1978/10/27/new-cameras-faster-films-handy-books/dfa757e8-73c4-4336-ae89-b2e0cea29253/ |title=New Cameras, Faster Films, Handy Books |date=October 27, 1978 |newspaper=The Washington Post |access-date=4 April 2023 |quote=The Ektramax takes 110-size, 400 ASA film and has a fast shutter speed for action and a slower shutter speed and wide f/1.9 lens aperture for available-light photography.

Over 25 million Pocket Instamatics were produced in under three years, and the 110 format remained popular into the 1990s. However, the small negative size (13×17&nbsp;mm) limited quality when using the film emulsion of the period; in practice, most prints were small, so the poor quality was not apparent unless the prints were enlarged beyond postcard size.
