Mitchell/Technovision, c. 1970

Mitchell, USA, Technovision, USA, agency Rome. Low-noise sound-film camera for motion picture production. This Technovision blimp body comprised a 35mm Mitchell reflex camera for 300 m film in Mitchell cassettes. Synchronous motor, without lenses. - Accessories: 2 cassettes for 300 m film, focusing via rack and pinion (on camera), camera-mounted rail for lamp, cables. - The by then high-quality subtractive color films freed American producers from the need to employ the complex Technicolor processes. The sound-proof blimp made tried and tested Mitchell cameras a popular choice for film studios. Technovision traces its origins to the period following the collapse of large American film studios that owned and operated their equipment. With branches in America, England and Italy, the firm hired out cameras, lenses and tripods under the name "Technovision". No matter whether the films were made in Hollywood, London or the Cinecittá Studios in Rome, the firm's cameras and lenses were always credited by name in the closing titles.
