Sorry, Willie, no personal experience with Instamatics. AI search revealed:
Kodak Instamatic cameras primarily use two distinct film formats: 126 film and 110 film.
126 Film: Introduced in 1963, this 35mm-wide cartridge produces 28x28mm square images (typically masked to 26.5x26.5mm). It features a single registration hole per frame and a captive take-up spool, allowing for easy drop-in loading without rewinding.
110 Film: Introduced in 1972 for the Pocket Instamatic line, this format uses a smaller 16mm wide film with a 13x17mm image area. It also uses a drop-in cartridge design but results in significantly smaller negatives.
While the term "Instamatic" is often used generically, 126 was the original format for the main Instamatic series, whereas 110 was reserved for the later, more compact Pocket Instamatic models.
