This led the company to specialize in lenses and shutters for the burgeoning movie camera market. Wollensak cinematic lenses were considered the best for decades. They were bought out by the Revere Camera Co. in the early 1950s. It is then that Revere began producing 8mm cameras with the Wollensak name. These were high-end cameras with the best lens available. They sold for twice the cost of the Revere brand cameras. The Briskens never fully combined the companies and the Wollensak operations remained in Rochester, NY.
Wollensak also made audio recording gear including reel-to-reel tape and 8-track recording equipment. The 3M company bought Revere Camera Co. including Wollensak in 1960. They continued to manufacturer and sell equipment until 1972.
