What are the functions of subjective lens?

The function of the subjective lens is to express the viewpoint of the characters in the film. When a character scans a scene or walks in a scene, the camera represents the eyes of the character and shows what the character sees.

as far as the impression of the lens on the audience is concerned, there are two kinds of objective lens and subjective lens. A shot described from the director's (and audience's) perspective is called an objective shot. A shot described from the viewpoint of the characters in the play is called a subjective shot.

The objective of subjective shooting is to make the audience have a sense of identity and see events from the perspective of movie characters. But generating identity is not a simple matter. The director can also gradually cultivate identity without using subjective lens, and obviously separate the camera from the characters.

Although subjective shots soon went out of fashion, the camera-character analogy still exists. Many Hollywood directors even insist that cameras should always move like people-not just subjective shots, but all kinds of shots. According to this view, the camera represents the eyes of an invisible witness, observing the movements in the movie world.

lens:

in film and television, a lens has two fingers, one refers to the optical components used by movie cameras and projectors to generate images, and the other refers to a continuous picture taken from power-on to power-off, or a fragment between two cutting points, which is also called a lens. One finger and two fingers are two completely different concepts. In order to distinguish them, one refers to the optical lens and the other refers to the lens picture.

according to the origin of lenses, they are mainly Japanese lenses and German lenses. Japanese lenses are mainly good in color reduction, while German lenses have a strong sense of hierarchy. China's lens in the market has gradually occupied a certain market, mainly because the price is relatively low.
