Three factors in judging fixed lens and moving lens

The difference between a fixed lens and a moving lens is: different viewpoints, different fluency and different composition changes.

But in the process of shooting a lens, the camera position, lens optical axis and focal length are fixed, and the shooting object can be static or dynamic. ?

Fixed lens is a static modeling method, the core of which is that the frame attached to the screen is not moving, but it is not completely equivalent to art works and photographic photos. The characters in the picture can move freely, draw a picture, and the light and shadow of the same picture can also change.

Specific differences between fixed lens and moving lens

Different viewpoints, fixed lens: the fixed lens has a single viewpoint, and the viewing area is limited by the frame of the picture. Action shot: the action shot has a comprehensive viewpoint, and the viewing area is not limited by the frame of the picture.

Different sense of fluency, fixed lens: fixed lens is easy to cause a sense of fragmentation, and it is difficult to fully and truly record and reproduce the original appearance of life. Action shooting: Action shooting is smooth, and the picture can completely and truly record and reproduce the original appearance of life.

Different composition changes, fixed lens: the modeling elements in the picture frame of fixed lens are relatively concentrated and stable, and it is difficult for a lens to achieve composition changes. Motion shot: The modeling elements in a motion shot are completely tiled and change with the change of shooting angle, so a shot can realize the change of composition.
