 In 1927, the camera 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).Early versions (The Filmo 70A and 70C) were designed for two speeds, either 8 and 16 frame/s, or 16 and 32 frame/s, with one option for a 12-16-24 frame/s 3-speed camera.
