Applications

Elmo is a Japanese manufacturer that built a widely used line of 16mm film projectors from the 1960s through the 1980s, popular in schools, churches, libraries, and government agencies across the United States and internationally. The ST series — including the ST-600, ST-800, and ST-1200 — were among the most common 16mm projectors in institutional settings. A 12.5mm focal length at f/1.8 is a standard short-throw, fast-aperture combination suited for smaller rooms where a bright image is needed at relatively close projection distances. Today these lenses are sought by collectors and restorers maintaining working Elmo 16mm projectors, as well as by filmmakers and archivists who use vintage 16mm projection equipment for screenings of archival or experimental film.
