The Sony EDC-55, released in 1988, was a professional-grade Betamax video camera designed for Extended Definition Betamax (ED Beta) recording. This model was part of Sony’s high-end ED Beta lineup, which aimed to compete with the growing dominance of S-VHS and early digital recording formats by offering superior video resolution and color fidelity.
Unlike Sony’s consumer-grade Betamovie camcorders, the EDC-55 was designed for professionals and broadcasters, featuring advanced imaging technology and enhanced connectivity options for studio and field recording.

Performance and Usage
The Sony EDC-55 was aimed at semi-professionals, independent filmmakers, and broadcasters looking for a high-quality analog recording solution before digital formats became mainstream. The ED Beta format provided significantly improved image quality over standard Betamax, making it a viable alternative to S-VHS and early Hi8 camcorders.
One of its standout features was the interchangeable lens system, which allowed videographers to adapt the camera for various shooting environments. Additionally, the inclusion of XLR microphone inputs meant users could capture broadcast-quality audio, making the EDC-55 a strong choice for documentary and field reporting work.
Legacy and Availability
Despite its technological advancements, the EDC-55 and the ED Beta format struggled against VHS-based competition, which had already established market dominance. By the early 1990s, professional users had transitioned to digital formats, making ED Beta a short-lived format.
Today, the Sony EDC-55 is considered a rare collector’s item, with few working models available due to the limited production and reliance on Betamax technology.
