Viewfinder for correction of anamorphotic reproduction - entails cylindrical lens, focussing screen, primary and secondary lens, esp. for mirror reflex cine camera.

摘要

The primary lens (6) consists of at least two cylindrical lenses (11), the axes of which are in alignment with that of the focussing screen (4). In the primary lens (6) in the direction of the radiation path (3) are successively arranged a cylindrical lens (11), two or more spherical lenses (12), and a further cylindrical lens (11). The primary lens (6) is firmly connected to the camera body (1). The primary lens connection to the camera body is via an exchange fitment which guarantees a clear orientation of the axes of the cylindrical lenses (11). USE/ADVANTAGE - For mirror reflex cine cameras, a view-finder for correction of anamorphotic reproduction.
