Applications
Photo-Sonic was a U.S. manufacturer specializing in high-speed 16mm and 35mm motion picture cameras used in scientific, industrial, and military cinematography — particularly for ballistics testing, crash analysis, aerodynamics research, and other applications requiring frame rates far beyond standard cinema cameras. The motorized take-up unit is a key accessory for these cameras, driving the film through the magazine at the high speeds these cameras demand and ensuring consistent, reliable film transport during a run. The 4B and 4C designations refer to specific Photo-Sonic camera and magazine configurations widely used in government, aerospace, and research laboratory settings from the 1960s through the 1980s. These units remain relevant today wherever Photo-Sonic 4-series cameras are still maintained and operated, as well as among collectors and archivists working with this equipment.
This Photo-Sonic Motorized Film Take-Up Unit for 35mm x 1000ft magazines (compatible with 4B and 4C models) has been inspected and is in good used condition. The housing shows typical wear for its age — paint chips and surface marks are visible on the flat body and mounting brackets, and there is some surface wear on the motor canister. The drive spindle, 4-pin connector, and cable all appear intact. Please review our photos for a full look at the cosmetic condition, and contact us if you have any questions before purchasing.
