A roll film adaptor is a specially designed attachment that allows cameras built for sheet or cut film to use roll film instead. This adaptor accommodates the width and spool mechanism of roll film formats, such as 120 or 220, enabling photographers to take multiple exposures without changing sheets.
Roll film adaptors are particularly useful for medium- and large-format photographers who want the convenience of roll film while maintaining the flexibility and control of their cameras. By using an adaptor, photographers can enjoy extended shooting sessions, reduce handling time, and still achieve high-quality negatives or transparencies.
