126 film

The term "126" was intended to show that 26 mm square images were recorded, using Kodak's common 1xx film numbering system.

[3] Like the 120 format, there is a continuous backing paper, and the frame number is visible through a small window at the rear of the cartridge.

Some of the higher-end cameras used this notch to determine the correct exposure, or to set the light meter, if so equipped.

[4] The film was originally available in 12 and 20 image lengths; at the time regular production stopped it was only available in 24 exposure cartridges.

The exposed film is stored on the take-up spool and does not need to be rewound, making the cameras very simple to load and unload.

Kodak published instructions for assembling a simple pinhole camera using a 126 cartridge with typical household materials.

With a few exceptions, the format was mainly used for fairly simple amateur cameras; some of the few high-end models were manufactured by companies included Kodak, Minolta, Rollei, Yashica and Zeiss Ikon.
