What does a wide-angle lens mean?

Wide-angle lens is a photographic lens with shorter focal length, larger viewing angle, longer focal length and smaller viewing angle than standard lens.

Wide-angle lens has a large viewing angle and a wide field of vision. The range of scenery observed from a certain viewpoint is much larger than that seen by human eyes at the same viewpoint; The depth of field is long, which can show a fairly clear range; It can emphasize the perspective effect of the picture, be good at exaggerating the foreground and express the sense of distance of the scene, which is conducive to enhancing the appeal of the picture.

It's difficult to get a shot with a wide-angle lens. There are too many scenes in the lens. To highlight the subject, it is necessary to guide the viewer's line of sight through the lines and composition of the picture, so that the viewer can pay more attention to the subject that the photographer wants to express.

Wide-angle lens is widely used to shoot large-scale landscape photography. Can increase the sense of spatial depth of the photo picture; The depth of field is long, which can ensure that the scene before and after the subject can be clearly reproduced on the screen. Therefore, the vast majority of modern pocket automatic cameras use ordinary wide-angle lenses of 38-35 mm

Wide-angle lens can shoot more scenery. If you don't want every photo to have a rich and complicated picture, you can try to leave a blank in the picture and make more changes.

The lens covers a large area and shoots a wide range of scenery; The scene shot at the same shooting distance is smaller than the scene image shot with standard lens in the picture; The defects of perspective distortion and image distortion are easy to appear in the picture. The shorter the focal length of the lens and the closer the shooting distance, the more obvious this defect is.
