Turn on the camera and select the photo mode. Open the AI photographer. Aim the camera at the object you want to shoot. When the mobile phone recognizes that you are shooting buildings such as tall buildings, it will automatically recommend the super wide-angle mode. You can click to switch to super wide angle to get a wider lens range. You can also slide and adjust the zoom lever in the viewfinder, or open and hold your finger on the screen to adjust the focal length.

Depth of field lens:

Depth of field lens is a kind of long lens with deep focal length. It is a means to realize the picture scheduling of the distant scene. This kind of lens is often used to keep the integrity of the picture and the unity of time and space. Its function is to express complete actions and events with one shot, and its meaning can exist independently, independent of its connection with the front and back shots.

It emphasizes the continuity of long lens in time and the function of complete space brought by deep focal length, forming a complex picture space structure with several planes contrasting with each other.

Because of this multi-level and multi-dimensional picture, fuzziness is derived, so that everyone has considerable freedom to choose and make their own judgment and understanding of part or all of the meaning of the picture image when enjoying the film.
