Diameter of annular defocusing zone of Xinle Xue

The diameter of the annular defocus zone of Xinle Xue is determined by the focal length, aperture size and other factors.

In terms of focal length, generally speaking, the longer the focal length, the smaller the diameter of the annular defocus zone; The shorter the focal length, the larger the diameter of the annular defocus zone.

In terms of aperture size, a smaller aperture (that is, a larger aperture value) will produce a smaller annular defocus band, while a larger aperture will produce a larger annular defocus band.

The diameter of the annular defocus area of Xinle Xue refers to the size of the annular defocus area produced by the lens during photography. This annular defocus zone will affect the clarity and focal length of the photo. It is very important for photographers to understand this concept.

The diameter of the annular defocus zone of Xinle Snow will be affected by ambient light. In the case of sufficient light, the diameter of the annular defocus zone will be relatively small; However, in the case of insufficient light, the diameter of the annular defocus zone will increase. The influence of ambient light on the annular defocus zone of the new music theory should be considered when taking pictures.

The quality of the lens will also affect the diameter of the annular defocus zone of the new music theory. A high-quality lens will produce a relatively small annular defocus zone in the imaging process; Inferior lenses may produce a larger annular defocus zone.

It is very important to know and master the diameter of the annular defocus zone of New Music School for taking high-quality photos. The size of the annular defocus zone directly affects the clarity and focal length of the photo. Photographers need to control the diameter of the annular defocus zone of Neo-Music by adjusting camera parameters or selecting appropriate lenses to obtain more satisfactory shooting results.

Characteristics of annular defocus zone in new music theory

1. Myopia defocus design: The lens consists of 396 microlenses, ranging from the single optical center area (normal vision area) in the inner hexagonal area to the myopic defocus area in the middle ring. It can ensure that the number of microlenses in the pupil is basically unchanged when the eyes rotate to the maximum extent, and it has good visual stability in daily use.

2. The defocus signal of myopia around the retina can control the axis, thus delaying the deepening of myopia. However, this design also has disadvantages. Because the degree of each microlens on the lens is constant, the defocus formed by the fundus is also fixed, resulting in less defocus in the area closer to the retina. If the child's training is slightly poor, it is not recommended to use new music.
