Filmo is a series of 16-mm and 8-mm movie equipment made by the Bell & Howell Company. The line included cameras, projectors and accessories.
The Filmo camera series started with the 1923 Filmo 70, beginning a series of models built on the same basic body that was to continued for more than half a century. It was based on Bell & Howell's brilliantly designed 1917 prototype for a 17.5mm camera intended for amateur use. When invited (along with Victor) into Kodak's 16mm plans in 1920, the company was quick to see the advantages and immediately set about redesigning the 17.5mm camera for 16mm film.
The Filmo 70 was the first spring motor-driven 16mm camera. In 1925 the Eyemo, a hand-held 35mm camera based on the design of the Filmo 70 was offered. It was also spring driven, but could be hand-cranked as well. Bell & Howell introduced the first 16mm turret camera with its Model C in 1927. A beautifully ornate and much more compact 16mm camera, the Filmo 75, marketed primarily as a "watch-thin" ladies' camera, was offered in 1928, followed in 1931 by a nearly identical counterpart designated as the Filmo Field Camera, offered initially in a plain covering, but also available with the ornate decorations of the Model 75, and in that form indistinguishable from the earlier version except for the nameplate.
When Kodak introduced 8mm film in 1932, Bell & Howell was slow to take up the new format, and when it did so, it was not in the form of the Kodak standard. The first 8mm Filmo was offered in 1935 as a single run 8mm film camera, the Filmo 127-A called STRAIGHT EIGHT. However, STRAIGHT EIGHT did not appeal to the market as well as double-8, so the design was modified for double-8 as the 134-A in 1936. Production of Filmos around this body type continued into the 1950s.
The 16mm Filmo cameras all take 16-mm film on a 100 ft (30 m) Daylight spool although some versions can also take 400 ft (120 m) external magazines.
Spring wind is standard, although some Filmos have provisions for attachment of a 12V DC or AC motor. A crystal-sync motor was developed for the Eyemo and later adapted to the Filmo.
The Camera is configured for C mount lenses and starting in 1927, was equipped with a three lens turret (Model C). Early turret models used a variable drum finder (Models D and DA) or sets of separate finder lenses matched to each focal length on later cameras (Models DL and DR).
