Kodak introduced it to fit smaller cameras and to make its own cameras take only its own film, and photographers still respool 120 film onto 620 spools today.
- Technology & computing
Kodak's 620 format, introduced in 1932, used the same film stock and frame size as 120 on a narrower, thinner spool. Production ceased in 1995, and users of surviving cameras respool 120 stock.
- Media & popular culture
K. 620 was written for a suburban commercial theatre rather than the court, which is why it is in German and mixes spectacle with formal composition.
