Film format between 16mm and 35mm — historically rare, mainly industrial and educational use. Collector's item today; technically a compromise without universal standards.
The 22mm format occupies a peculiar niche between established standards. While 16mm and 35mm became industrial and artistic norms worldwide, 22mm attempted a compromise—wider than 16mm for better image quality, cheaper to produce than 35mm. In practice, this middle ground never truly worked. The film cameras were expensive, raw stock costs were uneconomical, and there was a lack of a binding standard for perforation pitch and track spacing. Those who shot on 22mm quickly faced projection and duplication problems.
Historical Usage—22mm primarily appeared from the 1950s to the 1970s for training films, industrial documentaries, and occasionally for feature films in smaller markets. Some European and Soviet productions utilized the format because it seemed like a middle ground between cost-efficiency and image quality. However, without an international network of duplication facilities and projector manufacturers, 22mm remained regionally limited. A cinematographer working with 22mm had to plan their entire post-production within the same geographical radius—rough cut in the studio, duplication at the local lab, projection in equipped theaters. This made distribution a Sisyphean task.
Technical Reality—The larger image format than 16mm theoretically offered better grain structure and detail resolution, but this advantage was marginal—not significant enough to replace 35mm, not small enough to achieve the cost-efficiency of 16mm. The cameras themselves were one-offs or small series, often modifications of 16mm machines. Lenses were not standardized, and aperture calibrations varied between manufacturers. Those digitizing 22mm material today often find no more synchronization machines—they have to resort to external service providers or improvised solutions.
Collector's Item Today—22mm cameras and projectors are rare art objects in archives and collections. A technician who is knowledgeable about them is almost priceless. The few surviving films are digitized for cultural preservation reasons, but a restoration in the classical sense is economically pointless. For the modern cinematographer, 22mm serves as a cautionary example: formats that fall between global standards die out—no matter how technically elegant they may sound.
