The principle was based on the zooming lens. The wide-angle end could expand the shooting range, and the telephoto end could enlarge the subject.

It refers to the ratio of the image size of an object on the focal plane through the lens to the actual size of the object. The camera lens would be labeled as "maximum magnification", which referred to the lens 'maximum focal length (the focal length of the fixed-focus head was constant) and the closest shooting distance for clear imaging. For example, if the length of the object was 10mm, and the image on the film was 10mm, the lens magnification would be 1:1, the image would be 5mm, it would be 1:2, and the image would be 2mm, it would be 1:5. The macro lens was specially used to shoot small objects. Its magnification could usually reach 1:1, which could completely fill the image of the object being shot and clearly show the details and shape. At the same time, in the field of optical science, the magnifying power was one of the important indicators to evaluate the imaging ability and imaging effect of the lens. It was determined by the focal length of the lens and the closest focusing distance. In macro photography, the closest focusing distance usually determined the maximum magnifying power that the lens could achieve. In addition, the magnifying power was also an indicator of the camera viewfinder. If the magnifying power was large, the visual angle would be small, and the scenery seen during framing would be close to the original, giving a strong sense of realism. If the magnifying power was small, the visual angle would be large, and it would be easy to see the panoramic view during framing. Read more exciting novels for free
