Company profile of Leitz-Werke. After a view of the city of Wetzlar and Leitz-Werke from Kalsmunt, the film introduces various departments of the company: the milling shop, the engraving shop, the lens grinding shop, and the adjustment department. The film also shows the assembly of a microscope and a Leica camera.
