What is a cine lens?

The film lens has two meanings in film and television production: one refers to the optical components (physical lens) of the film camera or projector, and the other refers to the continuous picture segments (film lens) captured by the film camera from startup to shutdown, the latter being the basic unit of film composition. ‌‌
The core definition of movie shots
Physical lens: an optical component composed of glass or transparent material, responsible for imaging and light control, directly affecting image quality. ‌‌
Film shot: As the basic unit of a film, it includes elements such as continuous images, scenes, angles, motion patterns, sound, etc., and forms a complete narrative through montage. ‌‌
The constituent elements of film shots
Screen and scenery: including distant view, panoramic view, mid-range view, close-up view, close-up, etc., different scenery serves the narrative focus. ‌‌
Shooting angles: flat, upward, downward, upright, lateral and other angles affect the expressive power of the picture, such as upward shooting to enhance the sense of majesty. ‌‌
Camera movement: dynamic shooting techniques such as pushing, pulling, shaking, moving, and following to enhance visual rhythm. ‌‌
Sound and Length: The combination of sound and image forms a sound picture relationship; The length of the camera varies from a few seconds to several minutes, which affects the narrative rhythm. ‌‌
The particularity of movie shots (compared to ordinary shots)
The movie camera is designed specifically for dynamic images, emphasizing:
Durability: The all metal structure is suitable for high-intensity shooting environments. ‌‌
Accuracy of operation:
The focus ring has a long stroke (over 270 °) and supports precise focusing with a follower. ‌‌
Infinite aperture design (T-value calibration) ensures consistent exposure. ‌‌
Standardized design: The length, aperture, and weight of the same group of lenses are consistent, making it easy to replace quickly. ‌‌
