Why is the wide angle deformed?

1. Due to the related perspective characteristics, there will be a certain distortion when shooting with a wide-angle lens. When the subject is closer to the lens, the distortion of the subject image will be greater. In addition, the deformation is small near the center of the lens and serious at the corners.

2. A wide-angle lens is a photographic lens with a focal length shorter than a standard lens, a wider angle of view than a standard lens, a longer focal length than a fisheye lens, and a smaller angle of view than a fisheye lens. The lens of a wide-angle digital camera has a short focal length, a wide viewing angle, and a deep depth of field. It is more suitable for taking photos of larger scenes, such as architecture, landscapes and other subjects.

3. The basic characteristics of a wide-angle lens are that it has a large angle of view and a wide field of view. The scope of the scenery observed from a certain viewpoint is much larger than what the human eye can see at the same viewpoint; the depth of field is long and can show a considerable range of clarity; it can emphasize the perspective effect of the picture, and is good at exaggerating the foreground and expressing the scenery. A sense of distance, which helps enhance the appeal of the picture.
