Elmo C300 multi back cine camera, c. 1965. ASA 10, 20, 40, 50, 100, 160, 250, 320. Elmo Zoom lens f 1.8, F:9-36mm. Plus four packs of Double Run Super 8mm film, 60m (200 feet) each side. Produced 1965 to 1968 by Elmo, Japan.

This unsual camera was manufactured at the time that 8mm film was being superseded by the rival Super 8 (Kodak) and Single 8 (Fuji) film formats. Elmo, unsure of which format might survive, produced this unusual camera which had interchangeable magazines for all of the formats. It was electrically-driven (running at 18 or 24 fps) and had a reflex viewfinder with a rangefinder and through-the-lens exposure metering which could be manually overridden. It could also rewind 8mm and Single 8 film but not Super 8 film. The camera was imported into Britain by Ilford Ltd and cost £129-10-00 (£129.50) in 1968. In the USA it was known as the Honeywell Elmo Tri Filmatic.
