In film and television, there are two types of lenses: one refers to the optical components used by movie cameras and projectors to generate images, and the other refers to a continuous image taken from startup to shutdown, or a segment between two editing points, also known as a lens. One finger and two fingers are two completely different concepts. In order to distinguish between the two, one is often referred to as an optical lens and the other as the lens image.

In film and television, there are two types of lenses: one refers to the optical components used by movie cameras and projectors to generate images, and the other refers to a continuous image taken from startup to shutdown, or a segment between two editing points, also known as a lens. One finger and two fingers are two completely different concepts. In order to distinguish between the two, one is often referred to as an optical lens and the other as the lens image.
According to the origin classification of lenses, they are mainly Japanese and German lenses. Japanese lenses mainly have good color reproduction, while German lenses have a strong sense of hierarchy. Chinese lenses are gradually occupying a certain market share, mainly due to their relatively low prices.
The camera lens is the most important component in a camera, as its quality directly affects the quality of the captured image. At the same time, the lens is also the most important criterion for dividing camera types and grades. Generally speaking, according to the lens, cameras can be divided into three levels: professional cameras, quasi professional cameras, and regular cameras. Both traditional film cameras and digital cameras can be suitable for this classification. Lens can be divided into two categories: zoom and fixed focus.
In addition, there are different types of lenses such as wide-angle lenses, fisheye lenses, and telephoto lenses, each with different characteristics and applicable scenarios.
