Why are movie cameras so popular with s35 frame instead of full frame (cameras)?

Because 35mm is a full-frame sensor, that is, the diagonal length of cmos is 35 mm. This size comes from the film size in the film era, and the size of each 135 camera film is this large.

The dimensions and principles mentioned above come from still photography, that is, the photo industry. Now the question is about cameras, that is, the video industry.

Similar to the historical development of the photo industry, the cameras used in the video industry have also evolved from using film to digital imaging. The camera industry has entered the film era before digital imaging and is developing to the point where the most popular film size is super 35mm. , that is super 35 size.

The original movie cameras used 35mm film, which is the 135 format film used in our current film cameras. But the difference is that the frame of our 135 camera is 24mmX36mm, while the frame of the S35 camera, which also uses this type of film, is less than half of the full frame, which is close to or slightly larger than the APS-C frame.

The frame of the camera is horizontal, and the frame of the video camera is vertical. They use the same specifications of film. A brief summary is that these specifications and parameters are actually technical specifications that have been formed step by step under the development of technology and changes in the times.
