What lens was used on the earliest film camera in China?

China's earliest early film cameras used wooden-shell lenses. Early film cameras were made of wood and had only one lens, which was called cyclops camera. The photographer manually drives the camera to rotate the film. The invention of the camera was originally used for the production of movies and TV programs, but now it has become popular. Just like cameras, early cameras needed to use negatives (that is, video tapes) for recording, but now the invention of digital cameras enables images to be stored directly in flash memory. Newer cameras directly store image data in the hard disk of the fuselage, which can not only record dynamically and shoot statically, but also save the trouble of taking a digital camera at the same time. Family portable camera is light and easy to operate, and it is a necessary household appliance.
