Contax was a Japanese camera manufacturer that started production in the early 1930s. They made several different types of cameras and were known for their technology of swapping out different style lenses. This camera technology was in its infant stages, which helped launch the brand's overall popularity. Kyocera purchased the company and has since stopped production of Contax cameras in 2008.
