Applications

Elmo projection lenses like this 50mm f/1.2 unit were made for Elmo's line of 8mm, Super 8, and 16mm film projectors, which were widely used from the 1960s through the 1980s in homes, schools, and small institutions. The fast f/1.2 aperture allows for brighter projection in ambient light conditions or at longer throw distances. Today these lenses are sought by collectors and enthusiasts who maintain and restore vintage Elmo projectors, as original replacement optics can be difficult to find. A 50mm focal length is a standard projection lens for normal throw distances in the Elmo lineup.
